基于评价指标性状差异的工业用地集约利用评价研究——以义乌市为例

Evaluation of industrial land intensive use based on evaluation indicator character difference in Yiwu City

土地集约利用评价中集约度的测算是一个综合过程,受到一系列因素的影响,其中制度政策的影响促使评价的内涵、技术标准也应有所调整。首先,本文阐述了受工业用地标准控制政策的影响,工业用地集约利用评价指标出现性状差异,最终会影响集约度的测算精度;其次,运用对比分析的方法,通过与国家、地区工业用地控制标准的对比,对义乌市的工业用地集约利用水平进行初步分析,并简要探讨了现有标准的适用性;最后,为了检验评价指标性状差异对评价结果的影响,采用了熵权法的权重赋值方法,测算了义乌市的工业用地集约度,并与AHP方法测算结果进行对比。研究结果表明:①现有的工业用地控制标准还存在许多不足,有待进一步完善;②指标性状的差异确实影响到了工业用地集约度,若不考虑指标性状的差异,将得到一个高估的评价集约度;③通过与现有标准的对比分析以及进一步的测算,义乌市的工业用地集约利用水平处于中等偏下,有进一步提高的可能性及现实需要。

The aim of this paper is to illustrate that the accuracy of industrial land intensive use evaluation is affected by the indicator character difference,and entropy method as an improved method is mentioned later. Evaluation of land intensive use is a comprehensive process that affected by a series of factors. Connotation and technical standards of industrial land intensive use evaluation will need to adjust to the impact of policy which applied in industrial land control. This paper first elaborated that the evaluation indicators were affected by industrial land use control policy,and lead to difference of indicator character,ultimately influenced the measurement accuracy of evaluation. Secondly,according to the method of comparative analysis,by comparing with the national,regional industrial land use control standards,to the city of Yiwu industry carries on the preliminary analysis with the level of land intensive use,and briefly discusses the applicability of the existing standard. Finally,in order to test the influence of the evaluating indicator character difference on the evaluation results,we employed the weight assignment method of entropy method to measure land use intensity in Yiwu city,and compared with another evaluation result which AHP method was applied. The following research results:(1)The existing industrial land use control standards have many problems,needs to be further improved;(2)The evaluation indicator character difference affected the level of intensive land use exactly,and we will overestimate the level of intensive land use without considering indicator character difference in the evaluation;(3)Through comparing situation of industrial land use with existing standards and further estimates,the result showed that level of industrial land intensive use in Yiwu city is belong to medium degree,there are possibility and reality to improve it.
