基于GIS空间分析的农村建设用地节约集约利用研究

The Research on the Economical and Intensive Land Use of Rural Construction Land Based on GIS Spatial Analysis

中国农村土地利用粗放,基础设施建设落后,严重制约了农村居民生活水平的提高和中国城镇化进程。全国范围开展的土地整治工作目的就是改善农村农用地耕作条件和改良建设用地集约利用。文章运用景观格局理论和GIS空间分析技术,在建立农村居民点空间节地评价体系的基础上,结合农村居民点社会经济发展潜力评价,通过节地模式判定矩阵确定农村居民点建设节地方向和整理模式。文章宏观上分析了北京市通州区各乡(镇)空间节地情况,微观上对通州区台湖镇通过了空间节地评价和社会经济发展潜力评价,得到三镇农村建设用地节约集约利用的初步方案。

In China, rural land is wasted and used extensively and infrastructure construction lagged behind .All of these severely hin-der the improvement of living standards of rural residents and the urbanization process .Land remediation work carried out nationwide is aimed to improve the farming conditions of rural agricultural land and promote the intensive use of construction land .Based on the landscape pattern theory and GIS spatial analysis technology , this article has established the spatial pattern evaluation system in rural residential areas , and by taking advantage of the social and economic development potential evaluation and the judgment matrix , deter-mined the rural residential land consolidation mode .At the macro level , take Tongzhou district of Beijing as an example , analyzes the land space of various villages and towns .At the micro level, this article takes the Taihu town as an example , uses the spatial pattern evaluation and social economic development potential evaluation , and comes to a preliminary scheme for an economical and intensive use of rural construction land .
