城乡结合部农村建设用地集约利用评价及空间格局分析——以重庆市九龙坡区为例

为了缓解和解决城乡结合部地区城乡发展用地矛盾突出，以及农村建设用地集约利用水平较低的问题。以重庆市九龙坡区10个乡镇为研究对象，选取具有城乡结合部代表性人均居民点面积、耕居比、农村居民点人口密度、人均粮食单产、城镇化率等13个评价指标，建立城乡结合部地区农村建设用地集约节约利用评价指标体系，采用特尔斐法、层次分析法和多因素综合评价法分析对城乡结合部地区农村建设用地集约节约利用水平进行评价。根据其集约利用程度将10个乡镇分为3个等级，并以ARCGIS 9.3软件为技术平台，分析了研究区内农村建设用地集约利用水平的空间格局和聚集规律。结果表明，研究区域内农村建设用地集约利用的变化趋向在东北—西南向上为最为明显，而与之相反的西北—东南向的变化趋向较为平缓，并阐述了当前城乡结合部地区农村建设用地集约利用低效的原因，提出了提高城乡结合部地区农村建设用地集约利用水平的措施和建议。

The Evaluation of the Construction Land Use Intensity in Rural Areas of Quasi-urbanizationed Districts and

In order to ease the highlighted contradiction in land use for urban and rural development in urban-rural fringe areas, and solve the low intensive utilization of construction land use in rural areas, the author had selected 13 evaluating indicators such as the per capita residential area, the cultivated land residential land ratio, the population density of rural residential land, the urbanization rate, per capita output of grain, etc. and the 10 towns of Jiulongpo District in Chongqing as the research objects, established a evaluation index system to evaluate the intensive utilization of rural construction land through the methods of comprehensive Delph, the analytic hierarchy process and the comprehensive evaluation. The author had divided the intensive utilization degree into 3 level, analyzed spatial pattern and accumulation rules of the rural construction land in research area, it had concluded the obvious changing trend of land use intensity in those northeast-southwest area and the slow changing trend in northwest-southeast based on ARCGIS 9.3, presented the cause of the low intensive use level of rural construction in urban-rural fringe land and made some suggestions to improve the intensive use level.
