生态安全弹性与生态安全"倒U"曲线

文章从生态安全的研究现状入手,根据生态系统和人类社会系统之间的主要关系,论述了生态安全弹性和安全"倒U"曲线理论.生态安全弹性能够反映安全系数、安全阈值、干扰程度三者的关系,由它来判断人类向生态系统索取自然资源的活动更具有预测性、可操作性,并能保证生态系统自身也处于可持续发展的良性状态.

Ecosystem Safety Elasticity and Anti-U Curve

From the present points of the ecosystem research, the paper studies on the relation between human - being and ecosystem. Looking from the opinions of unisonous development it believes that the dominating relations between man and the nature are taking and giving as well as disturbing and maintaining. Studying on these interacting connections the article founds the rules such as safety elasticity and safety anti - U curve of ecosystem. Ecosystem safety elasticity which indicates the interplaying connection among safety modulus, safety limens and the degree of disturbing, could be used to analyze dynamically how much that human can take form ecosystem. Because of the divinable and operable merits ecosystem and human society could come into the benign living and evolving conditions.
