村级尺度下的农村居民点优化布局分析

从村级微观尺度出发,利用GIS技术手段与景观生态学原理相结合的研究方法,对重庆市荣昌县梅石坝村农村居民点优化前的空间格局、形态特征、景观指数、人均用地规模四项基本特征进行深入分析,结合实地调查归纳出农村居民点优化布局三项原则:①尊重农户意愿;②依托现有居民点适度集聚;③充分顾及基础设施和农业生产发展规划,并以此为基础优化现有农村居民点布局,分析优化后基本特征的变化,提出了"一村一核,一社一心"的优化布局模式。优化后的农村居民点布局实现了农村建设用地集约利用,更能满足农村发展的需要。

An Analysis of Optimized Distribution of Rural Residential Land in Villages

Using a method of GIS techniques combined with the principles of landscape ecology,this paper analyzes the four basic features before optimization,including spatial pattern,morphology,landscape indices,per capita land size,from the perspective of micro-scale village-level and induces three principles in the optimized distribution of rural residential areas.They are: respecting the farmers’ willingness,moderately concentrated according to existing settlements,and taking full account of infrastructure and agricultural development plan to optimize the structure of rural residential land and analyze the changes of the four basic features.Finally,the paper proposes the mode of "One Core for One Village,One Center for One Group".The optimized rural residential land achieves the intensive use of land for construction in rural areas and better meets the needs of rural development.
