洪湖湿地生态系统稳定性评价研究

运用生态学和系统学理论,建立洪湖湿地生态系统稳定性评价指标体系,利用层次分析法评价得出洪湖湿地生态系统目前为中度稳定状态。政策法令是影响洪湖湿地生态系统稳定性的最重要因素;其他因素依次为湿地水质、旱涝灾害系数、湿地景观格局和洪湖湿地调蓄能力等,而气候调节能力、人口密度和区域经济发展规模等因素对系统稳定性的影响则较小。

Stability evaluation of ecosystem on Honghu Lake wetlands

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.
