摘要
为明确东居延海湿地生态系统健康状况,基于PSR模型,从压力、状态、响应3个方面构建东居延海湿地生态系统健康评价指标体系,运用SPSS软件中的Pearson双变量分析,检验各分项指标与体系指数间的相关性.结果表明:东居延海湿地生态系统自然压力呈减小趋势,社会经济压力(人为压力)呈增大趋势;湿地中整体动植物响应状况明显,逐步向积极方向发展;湿地年代际健康状况为健康-亚健康-病态-亚健康-健康-很健康;东居延海湿地生态系统健康状况与入湖水量、动物种类的相关性最强,主要外界压力来自于渔业、旅游等方面.
In order to clarify the health status of the East Juyan Lake wetland ecosystem, the press-state-response model was used to con-struct the evaluation index system of the ecosystem health of the East Juyan Lake wetland. This index system included three primary indica-tors, namely pressure, state and response, and 13 secondary indicators. Further, Pearson bivariate analysis in SPSS software was used to test the correlation between each sub-index and the system index. The results show that natural pressure of East Juyan Lake wetland ecosystem is decreasing and social and economic pressure (artificial pressure) is increasing;overall response of plants and animals in the wetland is grad-ually developed in a positive direction;interdecadal health status of wetlands is healthy - sub-healthy - morbid - sub-healthy - healthy - very healthy;the health of East Juyan Lake wetland ecosystem is most closely related to the amount of lake water and animal species, and the main external pressure comes from fishery and tourism.
