景观生态破坏评价指标体系的建立方法和应用

本文在探讨景观生态破坏评价指标体系建立的目的和原则以及分析人类对景观生态系统影响的成因和表现的基础上，通过实例分析、讨论指标体系的可靠性和适应性。结果说明：水土流失率、景观类型多样性指数、生物量指数、开荒率、森林覆盖率等指标能够指示景观生态破坏的程度。

Establishment and Application of Index System of Evaluating Landscape Ecology Damage

Landscape ecology damage is a very serious problem in the world, In order to evaluate the landscape ecology damage. By means of Analytical Hierarchy Process(AHP),this dissertation established the synthetical index system from three aspects of landscape-stability,productivity,heterogeneity. On the aspect of stability, mostly choosing ratio of soil degenerating, ratio of cultivating wilderness , ratio of soil washed away, frequency of calamity, covering ratio of forest, cultivated area per capitia, population density, index of population diathesis 8 indexes; on the aspect of productivity, mostly choosing index of biological quantity,index of biological diversity,index of soil fertility 3 indexes;on the aspect of heterogeneity, mostly choosing diversity of landscape type, fragmentation of landscape,landscape isolation 3 indexes. By means of specialist consultation, make the weight of stability, productivity, heterogeneity 0.5179, 0.2468, 0.2353 separately, and calculated the compounded weight of indexes and ranked them, at last, it analyzed and discussed the reliability and suitability of the index system through an example and drew a conclusion: ratio of cultivating wilderness, ratio of soil washed away, diversity of landscape type, index of biological quantity and ratio of soil degeneration can be regarded as “indicator” of landscape ecology damage.
