荒地生态建设中稳定性分析方法

A method to judge the self-stable of landscape in deserted land corrected

在景观生态学理论与方法的基础上,采用定量的方法建立了荒地生态建设中的数学模型.针对三种尺度分析了荒地生态建设中的稳定性,重点研究了镶块体稳定性的高抗性稳定,并对局部稳定性中的阻止干扰的传播进行了深入研究.阐述了不稳定镶块体和景观异质性对景观整体稳定性的影响.

Stability should be analyzed according to such three different scales in ecological construction of wasteland as patch scale,local scale,and landscape scale.Patch stability includes physical stability,high recovery stability,and high resistance stability,and what pursue is high resistance stability.The base of local stability research views disturbance is a destructive factor to stability,and an important way to keep the local stability is prevent the disturbance from spreading.Landscape stability emphasizes the influences of the instable patch and landscape heterogeneity.
