新亚欧大陆桥新疆段水害时空分布与危险性区划

本文以新亚欧大陆桥段水害为研究对象，经过深入调查、实地考察和历史资料的收集，应用数理统计和构建模型的方法，从孕灾环境、致灾因子、承灾体等角度详尽研究了陆桥新疆段沿线水害的成因机理和时空耦合关系。分析了陆桥段水害危险性，并加以区划，旨在为西部大开发，建设大通道的防灾、减灾工作提供科学依据。文中创新之处可归纳为以下几点：1. 定性分析与定量相结合。论文注重学科的交叉应用，针对水害事件的突发性、随机性和难预测性等特点，突破以往对资料的收集整理和简单数据处理等传统研究方法的限制，在对陆桥段水害孕灾环境、致灾因子等分析的基础上，科学的运用灰色关联等非线形数学方法构建模型，对陆桥新疆段水害成因机理、时序分布等特性进行了研究和探讨。2.水害时空交叉耦合分析。在对陆桥新疆段近39（1959-1997年）年水害历史资料分析过程中，把时间序列和空间序列有机的结合在一起，通过时空交叉耦合分析，确定出陆桥沿线不同区段水害发生的重点时段，以及不同时段水害发生的重点区段。3. 从系统的角度研究水害事件。基于系统的思想，在提出铁路水害危险度等级划分原则、依据、方法和步骤的基础上，建立了陆桥新疆段水害危险性区划系统，从而丰富了铁路灾害研究的内容与方法。In this paper, take the flood disaster of Xinjiang Line of New Eurasian Continental Bridge as a research subject. After finished the work of investigation, inspection and date-collection, the cause mechanism of formation, dynamics characters and time-spatial regulation of the flood disaster of Xinjiang Line of New Eurasian Continental Bridge have been analyzed in the aspect of hazard-formative, hazard-formative factors and hazard-affected bodies by making use of Grey relative and Model Analysis. On the basis of theory analysis, the dangerous-degree division of sections of Xinjiang Line of New Eurasian continental Bridge has been determined regarding the events of flood disaster, which occurred in the past 39 years (1959-1997). All the work has been done with the aim to provide theory basis for forecasting hazard, preventing hazard and controlling hazard effetely in order to built road for guaranteeing western exploration. In this paper, the neoteric work are listed as following: 1. On the basis of determining the nature ,fixture quantity has been done. In this paper, limitation to the method of data-collection, settlement and disposition in natural hazard research has been broken through. What has been done is to pu attention to the intersect application of different subjects aimed at the natural disaster characters of random, complexity and paroxysmal. On the condition of analyzing of hazard-formation, hazard-formative factors and hazard-affected bodies, the cause mechanism of formation, dynamics characters and time-spatial regulation of the environment flood disaster of Xinjiang Line of New Eurasian Continental Bridge have been analyzed by using Grey Relative and Model Analysis. 2. Coupling analysis of the time-spatial series of flood disaster, In dealing with the history data of 39 years (1959-1997) of flood disaster of Xinjiang Line of New Eurasian Continental Bridge, put forward the means of coupling. after analyzed by combining the tie series with spatial series of flood disaster, the dangerous period of time of different sections and the dangerous sections of different period of time of Xinjiang Line of New Eurasian Continental Bridge has been determined in the paper. 3. Apply system theory to the flood disaster research. On the condition of system opinion, the sections division system of flood disaster has been established in the study of Xinjiang Line of New Eurasian continental Bridge on the basis of putting forward principle, method, process of distribution system, which enriches the content and method of railway flood disaster.

基于对地观测数据的城镇人口估算方法研究(英文)

本文对对地观测数据支持下的城镇人口估算方法进行了研究.首先,将研究区的居民地划分为高密度区、中密度区和低密度区,并且通过解译IKONOS数据获取各类型居民地的面积;然后,通过线性相关分析,研究居民地面积与居民人口之间的相关关系,并建立了相关关系式;最后,应用训练数据对居民地面积与居民人口之间的关系式进行了检验.结果显示:应用对地观测数据进行城镇人口估算,在理论上可信、方法上可行,是城镇应急状态下进行人口估算的可取方法

攀枝花泥石流发育的环境条件及其分布特征

攀枝花市大部分地区属泥石流重度危险区,所辖区县历史上多次受泥石流危害,现在仍有许多城镇、工矿、电站和交通设施受泥石流威胁。本区具有地质构造复杂、岩体破碎、新构造运动活跃、地震频繁的地质条件,坡陡谷深、谷盆交错分布的地形特征,降水集中、气温日较差大、干燥少雨的气候特点,再加上人类不合理的开发活动为泥石流的发育创造了良好的条件。受其影响,泥石流与断裂构造、地震活动、地层岩性、岩石风化程度、暴雨强度及人类活动具有空间分布上一致性。这不仅揭示了泥石流与其发育环境的关系,也为区域泥石流防灾减灾提供了依据

攀枝花泥石流沟谷形态的非线性特征

攀枝花市大部分地区属泥石流重度危险区,所辖区县历史上多次受泥石流危害,现在仍有许多城镇、工矿、电站和交通设施受泥石流威胁。区内泥石流沟主要分布在断裂发育、岩层风化强烈、暴雨频发的安宁河、金沙江和雅砻江河谷地带。通过对区内近200条泥石流沟发育状况统计分析发现,泥石流沟沟床比降、流域面积、主沟长度、形态数和相对高度在空间分布上具非线性的分形特征,与对应的泥石流沟条数具良好的非线性相关关系,表明泥石流系统的演化具自相似性。其中沟床比降和流域面积的分维值最小,对泥石流沟的形成、演变控制最为显著。这也在一定程度上揭示了这些泥石流沟谷形态演变的非均匀性和自相似性
