摘要:

针对城市开发区土地集约利用低、不能充分发挥其经济效益、社会效益和环境效益等问题,对各开发区进行了熵权模糊综合评价。本文以武汉市的16个开发区为研究对象,研究选取了重要程度较高,能客观反映开发区状况的10项指标,并利用熵权法对指标赋予权重;根据模糊变换原理及最大隶属度原则,构建了模糊综合评价模型;使用Python构建模糊计算流程脚本,输入权重及各指标值,计算武汉市16个开发区的结果向量,并利用最大隶属度原则确定了其对应的土地集约利用程度,从而得出武汉市16个开发区中处于集约开发利用的有4个,处于适度开发利用的有2个,处于过度开发利用的有1个,其余的9个均为轻度开发利用。采用ArcGIS查询统计和Voronoi图的CV值对4个集约利用的开发区进行分析,分析了这4个开发区企业、行政村、学校、医疗机构、基础服务设施的分布与利用状态。本文采用的土地集约利用评价方法具有较高的适用性,可为土地集约利用程度的提升提供现实依据。

Abstract:

The city development zone land shows many problems.So we use fuzzy comprehensive evaluation of development zones with entropy weight.This paper takes 16 development zones in Wuhan as the research objects.The study selects 10 indicators and uses the entropy weight method to target and constructs the fuzzy comprehensive evaluation model according to the principle of fuzzy transformation as well as the principle of maximum membership degree.We use the Python build script fuzzy calculation process to calculate the results of 16 in Wuhan city development zone vector.Finally we make use of the maximum membership degree principle to determine the corresponding degree of land intensive utilization.In the 16 development zones in Wuhan city,4 are drawn in intensive exploitation,2 are drawn in a moderate exploitation,1 is in the excessive exploitation and utilization and the rest 9 are drawn in mild utilization.In addition,this paper uses ArcGIS to query and statistic the CV of Voronoi diagram to analyze the state of 4 development zones in intensive utilization.The method used in this paper has high applicability and can provide the reality basis for land intensive utilization degree of ascension.

Key words: land, development zone, intensive utilization, entropy weight, the fuzzy synthesis, Voronoi, CV, evaluation
