水土流失是土地利用不合理造成的,但为什么长期以来直到今天,人们不能合理地利用土地呢?通过上黄村理论联系实际的分析,认为这是涉及到人口的环境容量问题。只有从这里出发考虑问题,所出之策,方有可能为治本之策,提出土地利用上人地关系的中心环节,并将它抽象为一简单等式:m_i=a_i×p_i。对此式作的分析,仍然认为一地区的人口环境容量是有限度的,提出一个完备的综合治理典型是生物与工程相结合的,但在方法上可分为两步走:先生物,后工程,才顺理成章。
Soil and water loss is caused by unreasonable land use, but why can not people make reasonable use of land for a long time? According to the analysis of the theory of Shanghuang village, it is considered as the environmental capacity of population. Only from this point of view to consider the issue, the policy, the party may be the solution to this problem, put forward the land use of the relationship between people and the central link, and abstract it as a simple equation: m_i = a_i × p_i. This type of analysis, still think a region’s population environmental capacity is limited, proposed a comprehensive and comprehensive treatment is typical of biological and engineering, but the method can be divided into two steps: the first biological, after Engineering, it is a matter of course.
