| 摘 要： | 基于评价指标的权重和隶属度值构建了广东省紫金县建设用地集约利用水平测度模型，运用最大相容类原则实现了建设用地集约利用水平的模糊识别分类，并通过将城镇及独立工矿区人均建设用地、农村居民点人均建设用地与国家2007年颁布的镇规划用地标准进行比较，测算了2005年广东省紫金县建设用地集约利用潜力.结果表明：2005年紫金县建设用地集约利用水平测度值为0.421，处于低效粗放利用阶段；理论上全县可减少555.69～2197.69 hm2的建设用地，集约利用潜力较大.

| Abstract: | Based on the weights and membership values of evaluation indices,a measurement model of construction land intensive utility in Zijin County of Guangdong Province was established,and the basic principles of the greatest compatible class were adopted to classify the intensive utility levels of the construction land based on fuzzy recognition.Additionally,the intensive utility potential of construction land in Zijin County in 2005 was calculated by comparing the per capita construction land in towns,independen... |
