我国土壤风蚀的研究,已发表了一些重要研究成果.土壤风蚀是一个自然-社会复合系统过程.影响土壤风蚀的自然因素主要有风速、植被、土壤粒度、土壤含水量.影响土壤风蚀的社会因子主要有土地翻耕、放牧牲口践踏等.它们本身是土壤风蚀的基本因子;又相互间影响、制约.依照系统动力学原理,利用计算机仿真技术,对这一自然-社会复合系统进行动态模拟,对于在更高层次上认识土壤风蚀规律有重要意义.我们以科尔沁沙质草地为例,对土壤风蚀的自然-社会复合系统动态过程进行了模拟研究.
The research on soil wind erosion in China has published some important research results.Erosion of soil is a natural-social complex system process.The main natural factors affecting soil erosion are wind speed, vegetation, soil particle size and soil moisture content.On the other hand, social factors affecting soil wind erosion Mainly soil plowing, trampling of livestock and grazing animals, etc. They are the basic factors of soil erosion and influence and restriction on each other.According to the principles of system dynamics, the dynamic simulation of this natural-social complex system is carried out by using computer simulation technology, It is of great importance to understand the law of soil erosion at a higher level.We take the Horqin sandy grassland as an example to simulate the dynamic process of the natural-social complex system of soil erosion.
