【摘要】 城市土地是城市社会和经济发展的基础。城市土地资源的数量和质量及其分配直接影响城市的经济、社会、环境以及综合效益。目前，我国城市土地利用效率低下的问题突出，城市土地结构不合理，其主要原因之一就是对城市土地的利用结构和利用效率缺乏科学合理的规划。本文将遥感与GIS技术应用于城市用地规划中，以常德市的城市用地总体规划为例，探索了定量评价的方法，讨论了评价过程中的一些关键技术。 本文论述了多源遥感影像数据融合技术，包括融合的信息表示、融合原理、融合系统框架模型、融合的算法、控制及应用。并将ETM遥感数据与大比例尺的地形图进行融合，利用非遥感数据与遥感数据融合调查城市土地利用现状及城市环境，以GIS作为支撑工具，建立城市环境空间数据库。针对城市用地的特点，运用多目标土地适宜性的评价方法，对常德市城市用地适宜性进行评价，主要探讨了主导因素与因子的选取，因子权重的确定，论述了如何借助地理信息系统的空间分析功能及图形和属性的结合实现城市用地适宜性的评价，分析了城市用地与城市环境协调性评价的指标体系，建立了城市环境综合评价模型。并在此基础上对城市用地现状进行分析研究，实现各类用地在空间上的优化配置，作出城市用地合理的规划方案。 结果表明，利用遥感与GIS相结合进行城市用地的调查与分析评价，可以快捷、准确地了解城市环境与用地的现状，合理布局和优化中南人学硕卜学位论文配置土地资源。 念华更多还原

【Abstract】 The land of a city is the base of the development of city’s society and economy.The quantity quality and distribution of a city’s land source affect the economy society circumstance and synthetical benefit of the city.At present,in our country,the utilize rate of city’s land resource is low and the structure of urban land use is not reasonable.The main reason of these is that there are not scientific and reasonable layout.In this paper,the technology of Remote sensing and GIS is used to this subject and the master plan of city Changde is taken as a case study to discuss some key 晅echniques in this process .Techniques for data fusion in multisources remotely sensed imagery are reviewed.Representation of information,framework,algorithms,control and applications of fusion are included.ETM remotely sensed imagery and large-scale relief map are fused together to make full use of effective information of remote sensing data and other data. A GIS-aided urban-environmental spatial database about the status quo of urban land use and environment is established according to the result of remete sensing survey. According to the characteristic of urban land use, applying a multi-objective method of appraisal,this paper analyses and appraises the land suitability for urban land use in city Changde. It focuses itsdiscussion on the selection of the chief elements and factors and shows how a multi-objective land suitability appraisal is achieved via the introduction of the application of Analytic Exponent Process and a combined analysis of spatial analytic functions,graphes and properties in the geographical information system.It analyzes the assessment of the coordination between various urban land uses and urban environmental potential.then establishes the evaluation model for different urban land uses and urban environment potential for each urban land uses category is evaluated.At last,on the base of these analyse and assessment, optimizing the structure of urban land use and putting forward scientific and reasonable lay out project.The analytical results indicate that the combination of remote sensing with GIS technology can be applied to the fast and accurate survey and assessment of urban land use, reasonable lay out ,and optimizing the structure of urban land use.更多还原
