The Research And Application On Multidimensional Statistical Method Of Urban Human Settlement Based On Webgis

With the development of the economic and the urban living standard in our country, growing attention is paid on the harmonious and beautiful living environment. Currently, the research of urban living environment is increasingly becoming the hot spot pursued by subjects. There are certain assessment criteria and evaluation systems. For the evaluation system will directly affects the quality of living environment evaluation, it should be considered from people-oriented, targeted, hierarchy, comparability, comprehensiveness, operability and relative independence in selecting evaluation indicators. The accuracy of index is depending on the reliability and integrity of the data sources. For the indexes affecting urban living environment refer to plenty of geospatial information, the traditional statistical methods and numerical statistical analysis are not suitable for the statistical research in urban living environment any more. Simultaneously, with the accelerated development of global information, technology and network, we should fully consider and use the important factors such as space-time, network, and information.In the context above, the thesis is committed to the research on urban living environment evaluation system and multi-dimensional statistical methods. WebGIS is a new geography information system technology combined with Geography Information System and Internet technology. It rises with rapid diffusion of Internet technology and plays important roles in people's production and living in the recent years. The thesis mainly studied three aspects as follows:1. Research urban living environment evaluation system, construct comprehensive urban living environment evaluation system, and evaluate the living environment quality of Qingdao in 2004-2008 with the criteria.2. Research urban living environment multi-dimensional statistical method. For selection of evaluation indicators is always restricted and constrained by statistical data, the thesis researches how to get ideal and high quality data, analysis data reasonably, and display the analysis result to people vividly and applies WebGIS in statistic collection, collation, analysis and display.3. With the research of urban living environment evaluation system and multi-dimensional methods, establish WebGIS-based Urban Living Environment Investigate and Statistical Analysis System.Based on the research above, a reasonable comprehensive urban living environment evaluation system is developed according to the characteristics of living environment. Simultaneously, the thesis explores the application of WebGIS in urban living environment quality statistic area, improves the method of data collection, collation, analysis and result display, to provide user browsing, querying and online-analyzing tool powered by the spatial analysis, statistical analysis and distributed operation of WebGIS, urban residents a platform supervising their surrounding living environment, statistical workers a quick quantitative survey analysis tool, decision-makers support in making urban planning and management decisions.
