| 摘 要： | 把山地稳定性与外界干扰作为一对基本矛盾，通过基本假定和参量选择，建立了山地稳定性强度与外界干扰强度相关变化的动态数量模型；在稳定性分析和演化方向分析的基础上，通过模拟计算，初步总结出有关山地稳定性演化和稳定性维护的五条结论。

A DYNAMIC NUMERICAL MODEL ABOUT THE STABILITY OF MOUNTANOUS REGION |

| Abstract: | Through basic hypotheses and parameter_determining,this article builds up a dynamic numerical model of the interrelating change between the stability_intensity in mountainous region (abbreviated to S in the following) and outside interfering_intensity (abbreviated to I ).After the analysis of stability and change directions,five pieces of conclusion are drawn up as follows: 1 Non_synchronous characteristic of two dynamic courses of S and I ; 2 Both changes of S and I have double characteristics of flexibility and hardness; 3 The structural characteristic of plant community is the leading factor in restricting change directions of S ; 4 Ecological factors have different sensitive degrees to the change of S or I ; 5 The maintenance of ecological stability of mountainous region should be first strategic step,then strengthening of that. |
