现代荒漠化过程中人为影响的系统分析——以内蒙古自治区乌审旗现代荒漠化过程为例

人类生产系统同资源环境之间存在复杂的多重反馈作用机制,现代荒漠化过程是人类活动不当造成的。本文对现代荒漠化过程中人为影响的系统分析表明：现代荒漠化过程中,各指标的变化速率不是一成不变的,而具有明显的阶段性；将控制人口增长速度与增加农牧业生产的物质技术投入、提高农牧业生产的集约化水平结合在一起,实行综合治理,是防治荒漠化的重要措施。

A SYSTEMATIC ANALYSIS OF THE MAN MADE INFLUENCE INMODERN DESERTIFICATION PROCESS

here is a complex multiple feedback mechanism between the man production system and the resource environment. The modern desertification process is caused by improper human activities . In this paper, we take Wushenqi of the Maowusu sand region as the research object and use the relevant theory of systematology to analyze the correlation mechanism between farming,animal husbandry, forestry, industry and population on one side and modern desertification on the other side. We also use the system dynamic method to simulate the development trend of the modern desertification in Wushenqi. The results indicate that in the modern desertification process the change rates of various indices do not remain unchanged, they have clear steps. It may be concluded that combining the control of the population increase speed with the increase of material and technology inputs in agricultural and animal husbandry production, increasing intensive level, and practicing comprehensive management are the main measures to prevent desertification.
