双模解析中国省域生态破坏性干扰指数

The Study on Ecological Destructive Interference Index Based on Dual Mode Analysis

我国生态环境日益严峻,当对生态的压力超过其承载力时,就破坏了生态平衡,并且难以修复。以干扰生态学作为理论基础,构建生态破坏性干扰指标体系,通过熵权法,使用全国30省域2005-2013年9年的数据,确定各指标权重,计算生态破坏性干扰指数,并采用双模思想解析指数结果,结论为地均工业增加值及沙化率两项重要指标对各省域生态系统威胁较大,我国多数省域的生态破坏性干扰指数分布不均衡,且数值较小,处于较安全的状态,但是指数呈现上升趋势。

Recently, the environment of China is worsening, however, if the pressure for ecosystem exceeds its bearing capacity, ecological balance will be destroyed, and become difficult to repair. Based on the theory of the interference of ecology, firstly, the paper constructs index system of ecological destructive interference, uses 30 provinces （municipalities and autonomous regions） of nine years （2005-2013） of data, and applies entropy weight method, determines each index weight. Then we calculate ecological destructive interference index, and analyzes index results by means of dual mode. Finally, the conclusion is that industrial added value per land and degradation rate threat the ecosystem mostly, and most provinces of ecological destructive interference index have an uneven distribution. Their index numerical value is smaller in a safe state, but the index shows a trend of rising.
