摘要
基于压力-状态-响应模型和城市湿地生态系统特点,通过建立指标体系和评价模型对长春南湖湿地生态系统健康状态进行动态分析。根据评价指标的选择原则,选取14个评价指标,提出5级评价标准,对南湖湿地的生态系统状况进行评价,明确各年的健康状况及制约因子。结果显示:2004~2008年,长春南湖湿地生态系统平均健康综合指数为2.582,整体处于亚病态,但总体上是在朝着健康方向发展,将评价结果与实际进行对比分析,证明评价结果是正确的。
According to the pressure-state-response model and urban wetland ecosystem characteristic,the healthy status of the Changchun South Lake of wetland ecosystem was expounded by establishing the index system and the evaluative model.On the principle of the selection evaluative target,14 indexes were selected and 5 level standers were put forward to evaluate south lake wetland.The health states and restrictive factors in each year were clear.The result showed that the average of health comprehensive index of Changchun South Lake wetland was 2.582 from the 2004 to 2008,and it was under sub-morbid state in general.Yet,by all accounts it was developing toward healthy direction.The comparison showed that the evaluation result of this method accurate.
