基于生态破坏性干扰视角的生态安全研究

Research on Ecological Security Based on the Destructive Interference

在干扰生态学理论的基础上,从生态破坏性干扰视角评价我国各省域的生态安全,构建了生态破坏性干扰指标体系,采用熵权法对各评价指标给予权重,对全国30省份的生态破坏性干扰进行评价,发现生态系统灾害类指标权重最大,沙化率的权重居首,30省份的生态破坏性干扰指数分布呈现不平衡的生态布局,其生态破坏性干扰指数存在差异性,90%以上省份的生态破坏性干扰指数处于较安全状态,受到的破坏性干扰程度较低。

This paper uses disturbance ecology theory, from the perspective of ecological destructive interference studies the ecological security, and build the evaluation index system of ecological destructive interference. Using the entropy weight method and giving every index weight, the paper evaluates ecological destructive interference of 30 provinces （municipalities and autonomous regions） in China in 2012. The results indicated that ecosystem disaster has the greatest weight, degradation rate the largest weight. The distribution of ecological destructive interference index over 30 provinces （municipalities and autonomous regions） is imbalance, and different provinces of ecological destructive interference index are different. Overall, more than 90% of the provinces of ecological destructive interference index is in a safe state, and destructive interference degree is low.
