The Rural Livability Evaluation and Its Governance Path Based on the Left-Behind Perspective: Evidence from the Oasis Area of the Hexi Corridor in China

The evaluation of rural livability for different groups of left-behind people and proposing classified governance paths are of great practical significance to solve the problem of sustainable development of left-behind villages. Taking Jinchang, China as an example, this paper aims to construct a rural livability evaluation index system based on identifying the types of left-behind villages, which combines the “individuality + commonality” of different left-behind subjects, analyzes the livability level of left-behind villages and proposes a classified governance path to help solve the problem of sustainable development of left-behind villages. The results show the following: (1) The types of left-behind villages are mainly left-behind children and left-behind elderly types, accounting for 68.75% of the total number of left-behind villages. (2) There are large differences in the livability of individual characteristics of the villages. The average livability for children is the largest, reaching 0.6608. The average livability for women is the smallest, being only 0.1418. The livability values for the elderly and children are mainly in the medium-value areas, while the livability for women is mainly in the low-value areas. (3) The overall livability level of the villages is low, mainly falling in the low-value areas. The evaluation units with values higher than the average accounted for 40.625% of the total. The level of meeting the demands of the left-behind population in villages is low. The overall levels of economic development, public services, infrastructure, and configuration need to be optimized and improved, and the living and production conditions need to be further improved. (4) According to “left-behind + livable”, we classified the villages into five types: optimizing and upgrading villages, improving short-board villages, balanced developing villages, upgrading potential villages, and comprehensive upgrading villages. In the future, it is necessary to carry out classified governance from various aspects, such as improving governance, making up for shortcomings, coordinating and balancing, and comprehensively improving quality to achieve the ultimate goal of sustainable rural development

From Subjective and Objective Perspective to Reconstruct the High-Quality Tourism Spatial Structure―Taking Gannan Prefecture in China as an Example

Spatial relationship is the basic perspective of understanding regions. Tourism spatial structure is the spatial projection of tourism activities, reflecting the spatial attributes and interrelationships of tourism activities. In this paper, taking Gannan Tibetan Autonomous Prefecture as an example, we identified the objective and subjective tourism spatial structure of Gannan Prefecture based on the GIS spatial analysis function and using objective and subjective tourist attractions as the spatial object element. Then, the tourism spatial network was reconstructed. Results are as follows. (1) Both objective and subjective tourist attractions in Gannan Prefecture exhibit aggregated distribution. Among them, the spatial distribution of objective tourist attractions has a significant trend of contiguous aggregation, showing a relatively higher density in the northeastern and southeastern regions, and a lower density in the central and southwestern regions. This is opposite to that of the subjective tourist attractions. (2) The connectivity and accessibility between objective and subjective tourist attractions in Gannan Prefecture are poor, and only a few tourist attractions form a traffic connection with neighboring ones. (3) The objective tourism spatial network of Gannan Prefecture is layered with aggregation, and presents a significant cohesive development trend. This is opposite to the subjective one. (4) Based on the identification results of objective and subjective tourism spatial structures, the objective and subjective core tourism resources as well as tourist attractions should be integrated, and the road transportation system should be constructed and improved. Then, a high-quality tourism spatial network with ‘three poles, three axes and four groups’ was constructed. This study provides a scientific basis for the tourism spatial development, tourist route organization, the layout of tourism service facilities and product, and tourism spatial optimization in specific regions

The Equity of Basic Educational Facilities from the Perspective of Space

Basic education pursues “balance” and “quality” under the premise of “universalization”. High-quality and balanced education is the general strategy of international education. We used urban network tools to measure the spatial equity of three types of basic educational facilities (kindergarten, primary school, and middle school) in the main urban area of Lanzhou City, China, from the perspective of supply and demand. This can optimize the allocation of educational facilities, and make up for the shortage of basic educational facilities. It can also provide a scientific reference and new ideas for research on public service facilities. The conclusions are: (1) The distribution of basic educational facilities presented a typical pattern of belt-shaped clusters, river trends, and dense east and sparse west. The spatial dislocation between facilities and residential buildings was significant and occurred in numerous instances. (2) The supply of basic educational facilities was weak. There were significant differences in spatial accessibility among different types and regions. The spatial accessibility of kindergartens (34.83%) was the best with regard to walking conditions, followed by primary schools (27.43%) and middle schools (21.11%). (3) The distribution of basic educational facilities was affected by factors such as historical development, natural geography, social economies, and the travel behaviors of residents; (4) It is necessary to improve the problem of spatial imbalance through the implementation of refined planning management and resource allocation of infrastructure, the construction of a “community life circle”, and the establishment of an early warning mechanism for academic degree attainment combined with big data

The Impact of Farmland Management Scale on Carbon Emissions

In rural China, the conversion between fine-grained farmland and large-scale farmland is a widespread phenomenon, changes in the size of farmland can have an impact on agricultural carbon emissions. Based on the agricultural panel data of Gansu Province for 2000–2020, taking the scale of agricultural land management as the breakthrough point and the consumption intensity of agricultural materials as the intermediary factor, this paper discusses the driving mechanism of agricultural carbon emissions by the scale of agricultural land management. The results including: (1) From the perspective of the intermediary effect, large-scale farmers pay more attention to input efficiency of chemicals such as fertilizers than small-scale farmers, which can effectively promote the development of low-carbon agriculture. (2) A “U-shaped” relationship existed between agricultural land management scale and agricultural carbon emissions. The agricultural carbon emissions were the lowest when agricultural land management scale in Gansu was 0.608 hm2/person. (3) The carbon emission intensity reached its peak when the scale of farmland management in the Hexi region was 0.143 hm2/person. The optimal scale of farmland management in the Longdong and Longnan regions was 0.143 and 0.348 hm2/person, respectively, Longzhong and Gannan regions was all showed complete intermediary effects
