基于GIS的招远市农村居民点布局适宜性研究

The Study on the Spatial Distribution of Rural Residential Land In Zhaoyuan County Using GIS

以招远市为例,研究农村居民点的空间布局.采用层次分析法、专家打分法为农村居民点用地现状建立评价指标体系,并用GIS软件建立空间数据库,用空间叠加分析、空间缓冲分析、空间数据的集合分析和查询等GIS空间分析方法及相应的数学模型对农村居民点的空间布局现状进行分析,并根据综合评价将农村居民点用地现状分级,分析出农村居民点空间布局中存在的问题,为农村居民点的空间布局提出合理性建议,各乡镇可以根据各自的经济发展水平和地理条件分别采用合适的模式.本论文对招远市农村居民点的用地规划具有一定的指导意义.

The paper studies the spatial distribution of rural residential land taking Zhaoyuan County as an example. It builds a target system to evaluate the present conditions of rural residential land using the method of Analytic Hierarchy Process and Delphi Method . It builds the spatial database by Maplnfo7.0, And it analyzes the spatial distribution of rural residential land with the math models and GIS spatial analytic methods ,such as spatial overlay analysis ,spatial buffer analysis, spatial query analysis and so on. It classifies the present conditions of rural residential land according to the result of evaluation. And it finds the problems of spatial distribution and puts forwards many reasonable proposes. Every small town can choose suitable ways according to its financial condition and geographical factors, the paper has some guide function to the plan for the rural residential land of Zhaoyuan County.
