Study on Ecological Security Evaluation of Land Resources in the Case of the Core Areas of Zhongyuan Economic Region
摘要
Abstract
The evaluation index system of land resources ecological security of the core areas of Zhongyuan Economic Region was constructed based on AHP and entropy weight method,and the dynamic of land resources ecological security of the core areas of Zhongyuan Economic Region during 2002-2011 was evaluated.The results show that the land resources ecological security index increased to 0.675 5 in 2004,and the land security rating indicated ' Ⅱ '-safe level.However,the land resources ecological security index declined to 0.310 6 in 2011,and the land security rating indicated 'Ⅳ '-less safe level.During 2002-2011,the dynamics of land resources ecological security showed a single peak curve in Zhengzhou,Xuchang and Jiaozuo,a bimodal curve in Kaifeng and Xinxiang,and an 'U' curve in Luoyang.Moreover,the spatial change of land resources ecological security was characterized as a center of Zhengzhou,worsening in south and north region,improving in east and west region in the core areas of Zhongyuan Economic Region关键词
