基于熵权TOPSIS模型的福建省土地利用绩效评价及灰色关联分析

Evaluation and Grey Correlational Analysis of Land Use Performance in Fujian Province Based on Entropy-weight TOPSIS Model

基于福建省土地利用的背景与现状,从土地利用经济绩效、社会绩效和生态绩效3个层面构建土地利用绩效评价指标体系,运用熵值赋权法确定其指标权重,采用改进的TOPSIS模型评价分析2006-2016年福建省土地利用绩效的状况,并用灰色关联分析法分析影响土地利用绩效的主要因子.熵权TOPSIS模型研究结果表明:2006-2016年,福建省土地利用综合绩效呈逐年递增的态势,经历了低级绩效阶段(2006-2009年)-中级绩效阶段(2010-2012年)-良好绩效阶段(2013-2014年)-优质绩效阶段(2015-2016年)的演变历程.灰色关联分析结果显示:福建省土地利用经济绩效对土地利用综合绩效的影响最为显著;土地利用社会绩效对土地利用综合绩效有明显的推动作用;相比之下,土地利用生态绩效对提高土地利用综合绩效的贡献度并不突出.

In view of the background and present situation of land use in Fujian province,sets up land use performance evaluation index system from economic performance,social performance and ecological performance of land use,uses entropy weighting method to determine the index weight,uses improved TOPSIS model to evaluate the performance of land use in Fujian province from 2006 to 2016,and then the key factors affecting the performance of land use are analyzed by the grey correlation analysis method.The research results of entropy-weight TOPSIS model show that from 2006 to 2016,the land use comprehensive performance in Fujian province shows a trend of increasing year by year,experiencing the evolution process of low performance stage(2006-2009)-intermediate performance stage(2010-2012)-good performance stage(2013-2014)-high quality performance stage(2015-2016).Grey correlation analysis results show that the economic performance of land use in Fujian has the most significant impact on the comprehensive performance of land use; the social performance of land use has a significant role in promoting the comprehensive performance of land use; In contrast,the contribution of land use ecological performance to improving the comprehensive performance of land use is not outstanding.
