基于CAS理论的土地系统脆弱性演化机制分析

Analysis on Evolution Mechanism of Land System Vulnerability Based on CAS Theory

基于土地系统的复杂适应特征,从CAS理论的角度对土地系统脆弱性的演化机制进行分析,从系统层、子系统层、主体层多个层次分析了各个主体在影响土地系统脆弱性的产生及演化中的地位与作用。结果表明,在土地系统脆弱性的演化过程中,政府的宏观调控行为起到一定程度的决定性作用,其会使土地系统脆弱性呈现出2个演化方向;而政府通过积极管理,采取合适的调控措施,将有利于促进土地系统脆弱性向良性方向发展。

According to the complex adaptive characteristics of land system, the paper analyzes the evolution mechanism of land system vulnerability based on CAS theory ,which mainly studies the role of each adaptive agent in the generation and evolution of land system vulnerability from the perspective of the system level, subsystem level and the adaptive agent level. The results indicated that macrocontrol behavior of the government plays a decisive role to some extent in land system vulnerabilities evolution. It will make land system vulnerability present two evolutionary directions under government macro-control. The active management and appropriate measures will facilitate land system vulnerable to a positive direction.
