Fast micro-differential evolution for topological active net optimization

This paper studies the optimization problem of topological active net (TAN), which is often seen in image segmentation and shape modeling. A TAN is a topological structure containing many nodes, whose positions must be optimized while a predefined topology needs to be maintained. TAN optimization is often time-consuming and even constructing a single solution is hard to do. Such a problem is usually approached by a ``best improvement local search'' (BILS) algorithm based on deterministic search (DS), which is inefficient because it spends too much efforts in nonpromising probing. In this paper, we propose the use of micro-differential evolution (DE) to replace DS in BILS for improved directional guidance. The resultant algorithm is termed deBILS. Its micro-population efficiently utilizes historical information for potentially promising search directions and hence improves efficiency in probing. Results show that deBILS can probe promising neighborhoods for each node of a TAN. Experimental tests verify that deBILS offers substantially higher search speed and solution quality not only than ordinary BILS, but also the genetic algorithm and scatter search algorithm

Land Use Conflict Detection and Multi-Objective Optimization Based on the Productivity, Sustainability, and Livability Perspective

Land use affects many aspects of regional sustainable development, so insight into its influence is of great importance for the optimization of national space. The book mainly focuses on functional classification, spatial conflict detection, and spatial development pattern optimization based on productivity, sustainability, and livability perspectives, presenting a relevant opportunity for all scholars to share their knowledge from the multidisciplinary community across the world that includes landscape ecologists, social scientists, and geographers. The book is systematically organized into the optimization theory, methods, and practices for PLES (production–living–ecological space) around territorial spatial planning, with the overall planning of PLES as the goal and the promotion of ecological civilization construction as the starting point. Through this, the competition and synergistic interactions and positive feedback mechanisms between population, resources, ecology, environment, and economic and social development in the PLES system were revealed, and the nonlinear dynamic effects among subsystems and elements in the system identified. In addition, a series of optimization approaches for PLES is proposed

Spatial and temporal aspects of land use in the urban-rural fringe in china: a GIS approach

Since the reform in 1979, China's rural and urban economies have been extremely active. This has accelerated greatly the urbanisation process in the peripheral areas of metropolises. Urban regions extended into rural areas by way of urban sprawl and population concentration in the rural-urban fringe, in which the types and structures of land use changed rapidly. The rural-urban fringe has been an extremely active area in contemporary Chinese socio-economy. It is also a belt of concentration of development and construction of rural and urban kinds. In seeking to apply geographical information systems to such an important area of land use change, this research studies the general principles of the formation, evolution and development of rural-urban fringe with a case study in Tianhe District of Guangzhou Municipality, China. This research analyses the following three aspects of land use change. Firstly, the land use conditions and situations are discussed in the form of their fundamental characteristics in various years. Secondly, the spatial changes of land uses are characterised in terms of the distance from the city centre including the effects of the physical landscape. Finally, the main emphasis is put upon the impacts of policies on land use distribution. Three different time periods (1973, 1993 and predicted 2010) are applied to compare the changes of land use. According to the analysis of the trend of land use change in this study, the development of Tianhe District from a traditional rural area to a rural-urban fringe is a considered as result of the Guangzhou urban sprawl. Its specific location, economic development levels, population conditions and policy advantages have influenced this evolution process and brought about the spatial changes and spatial structure of land use.

Between Flexibility and Reliability:

The aim of this research is to provide an outline to address questions with regard to the transformation of planning in China that has occurred after the 1980s. The research is using “planning evolution” as the main research skeleton. The starting point is to investigate to what extent Chinese urban planning has developed after the opening up and other reforms under the state-led and market-driven modes of Chinese reformation, and to investigate how the different modes and various actors have influenced urban planning, based on the investigation of the respective political and economic changes within the initial reformation in general, and planning in particular. In recent years, China has undeniably undergone a dramatic process of urban growth and transformation. Apart from its speed and scope, it is less recognized that these processes are confronting the Chinese planning institutions with new and unexpected demands almost on a daily basis. In reference to the increasing importance of private investments and developments within the Chinese urbanization process, a new balance between public planning and private developments, and between top-down and bottom-up approaches is required to be able to generate both a reliable and responsible framework for long-term urban development and a flexible system of implementation that meets the needs of changing conditions and new demands. Flexibility and reliability become the new demands for planning practice. Based on the theory of planning culture, planning traditions, concepts, systems and decision-making processes are always related to the cultural context and cultural background of the people and societies involved. Investigating the contemporary urban transformation and urban development processes in China can allow us to outline the new planning culture of contemporary China in relation to its historical roots and traditional characteristics in a long term framework. I argue that the changing role of urban planning is strongly embedded in the political, economic, and social domains and is a part of cultural innovation. The research opens a general debate on the circumstances of the contemporary Chinese transformation after the 1980s. After introducing the idea of planning culture and elaborating to what extent the idea of planning culture is applied in this research, I argue that the “soft” characteristics of planning emphasized by the idea of planning culture are crucial to understand Chinese planning evolution. The idea of planning culture is applied to build up the theoretical framework needed in order to approach the research subject: the contemporary Chinese transformation, based on a systematic structure. Overall, this research states the following. 1). The reversal of Chinese policies in 1978 and the opening up of the country to foreign investments and technology were taking up the job that had been left unfinished in 1949. The momentum is regarded as a part of the long-term evolution of Chinese modernization, for which the term of “critical-modernity” is introduced, situating the changes within the broader context of the globalization. It cannot be disconnected from the roots of Chinese history and tradition and as such is an alternative to Western paradigms. 2). The dissection of the specific Chinese historical evolution results in a sequence of layered modes of hybrid development. 3) Situating the political-economic momentum of the 80s in a longer time span and exploring it beyond the political status of the time by making the contextual linkage to the cultural and traditional consensus of Chinese history, it is seen as a “cultural turn” of Chinese society. 4). This study applies the idea of “planning culture”—to compare different periods in one country and to analyze the changes that have taken place with regard to both the planning system and the cultural context; and to approach urban planning transitions from political, social, and economic aspects by investigating the conditions, approaches, and results of current spatial planning in China. According to the application of the idea of planning culture as a systematic framework, the research comprises three major research themes: the transformation of society, the transformation of the planning system and the implementation of planning in practice. The Transformation of the Society comprises two parts. The first reviews the philosophical roots of the Chinese norm and value system and the second part introduces the contextual background of the emerged evolution of Chinese modernization. The purpose is on the one hand to anchor the contemporary Chinese transformation within the Chinese context, and on the other hand to argue that the transformation of contemporary China in the 1980s is a new turn that is part of the evolution of modernization. The Transformation of the Planning System offers the specific information about the transformation that took place in the 1980s, in particular in relation to the reforms initiated by the central government. The focus is in on the re-modification of the urban planning system after 1978; special attention is given to the political structure, planning organization, and plan forms. It is the analysis of the top–down system. The Implementation of Planning System in Practice zooms further in on the micro-scale of planning evolution by analyzing the planning implementation in practice in one of the fastest growing cities of the country: Shenzhen, located in the Pearl River Delta, which can be regarded as an almost newly constructed city with approximately 300.000 inhabitants in 1980 and reaching 10.47 million in 2011. During a relatively short period of development the degree of acceleration and the scope of an entirely unexpected growth forced local planning authorities to constantly readapt to changing conditions and new demands. In this framework, different planning documents and the process of decision-making are analyzed, with special attention to the coordination and fine-tuning between planning intervention and planning implementation. These three clusters of research themes serve to answer a series of research questions respectively. The main research question is: How does urban planning in contemporary China face the challenges of the emergent urban evolution within the current world society? This research argues that planning strategies have to be developed, on the one hand under the circumstances of inevitably increasing uncertainties in China society generating the flexibility for new and unexpected developments, and on the other hand to confront the unpredictability and uncertainty of initiatives from diverse public and private actors by generating and building up a reliable framework for sustainable long-term developments. Planning embodiment (ideology, aim, system etc.) must be understood and used not only for political-economical interventions but, furthermore, as a spatial agent in order to mediate the changing confrontations of socio– spatial demands embedded in the cultural domain, instead of being used only as a top–down dominating intervention tool. China enters a critical era of modernity, a society in which to retrieve the socio-spatial meaning for people is a much more powerful force than only focusing on economic success and political stability. This reflection shall be based on the revival of Chinese traditions and values and the re-evaluation of those values in a systematical manner. However, in comparison with drawing a concrete conclusion, this study’s intention is to inspire reflection, to provoke further debate and to disclose and dissect the context of Chinese planning culture. It is by the same consideration that I found the idea of planning culture a useful and valuable framework to access urban development and planning evolution in non-Occidental countries. The “soft” core of planning culture has the same essential cultural value everywhere, and for countries like China who share the similar hybridity of evolutional history, the processes of industrialization, urbanization, decolonization, Westernization, post-industrialization and globalization are affecting the country not in a linear–subsequent manner, but on different layers simultaneously and sometimes with contradicting demands. Being embedded in this unique Chinese political–socio–economic environment, urban planning is used by the state as a powerful instrument providing a vision for the country’s future in the transitional process between the rules of both extreme modes of top-down and bottom-up approaches, balanced by involving the governmental and public sectors simultaneously. I am convinced that the idea of planning culture can trigger a new wave of discourse leading to a completely new insight in and understanding of cultural differences, not only in an abstract sense for Chinese culture but also in general for everybody whose live is strongly influenced by planning decisions and whose daily activities are interactively incorporated in the socio-spatial domain. &nbsp

Physical Planning Strategies of National High-Technology Industrial Development Zones in China

Over the last two decades, High-Technology Industrial Development Zone (HIDZ) has become an important strategy for urban development in China. Modeled on earlier examples in the US and Asia, they have developed in unique ways in China because of the rapid urbanization, large-scale sites, and trend toward high-technology-based new townships or technopoles. While the 84 current national HIDZs widely use planning strategies in their government-guided development and construction, the impact of these planning strategies remains is not well understood. This dissertation explores how and to what extent planning and management strategies impact the outcomes of HIDZs. It examines closely four case examples (Beijing Zhongguancun Science Park, Shanghai Zhangjiang High-Technology Park, Suzhou Industrial Park, and Shenzhen High-Technology Industrial Park). The study reveals the diverse and sometimes competing purposes of national HIDZs, ranging from stimulating innovation and improvement of products, to serving as an economic anchor and a tool for attracting international firms. The research demonstrates the importance of adopting a sustainable strategy for development of HIDZs that it guides place-making, regulates the land development process, improves the quality of the environment, facilitates cooperation among various sectors, and attracts investment. It explores the versatility of planning approaches, identifies a series of key factors that shape planning strategies, and provides suggestions for tailoring the approach to planning to local resources and conditions

New Industrial Urbanism

Since the Industrial Revolution, cities and industry have grown together; towns and metropolitan regions have evolved around factories and expanding industries. New Industrial Urbanism explores the evolving and future relationships between cities and places of production, focusing on the spatial implications and physical design of integrating contemporary manufacturing into the city. The book examines recent developments that have led to dramatic shifts in the manufacturing sector – from large-scale mass production methods to small-scale distributed systems; from polluting and consumptive production methods to a cleaner and more sustainable process; from broad demand for unskilled labor to a growing need for a more educated and specialized workforce – to show how cities see new investment and increased employment opportunities. Looking ahead to the quest to make cities more competitive and resilient, New Industrial Urbanism provides lessons from cases around the world and suggests adopting New Industrial Urbanism as an action framework that reconnects what has been separated: people, places, and production. Moving the conversation beyond the reflexively-negative characterizations of industry, more than two centuries after the start of the Industrial Revolution, this book calls to re-consider the ways in which industry creates places, sustains jobs, and supports environmental sustainability in our cities.
