洪湖湿地生态系统稳定性评价研究

Based on the theories of ecology and system,the evaluation index system of ecosystem on Honghu Lake wetlands was established,and the evaluation using analytic hierarchy process shows that on Honghu Lake wetlands,the system is in a state of middle stability. Many elements affect the system. Policy and decree are the most important factors,and the second are wetland water quality,disaster coefficient,wetland sight pattern and regulating sluice ability. The adjusting ability of climate,the density of population and the scale of economy development of the region affect the stability of the system weakly.
