| 摘 要： | 在洪泽湖野外调查采样的基础上,利用地理信息系统等工具,通过选择湖泊生态健康评价指标、计算各指标指数、确定各指标权重、综合计算生态系统健康指数等步骤,分区评价洪泽湖湖泊生态系统健康状态。结果表明,洪泽湖不同湖区生态系统健康状况存在一定差异,呈现由西北部湖区向湖心区和东南部湖区递减的趋势。通过对洪泽湖湖泊生态系统健康分区评价研究可以找出湖泊生态脆弱区,进而为湖泊保护与开发提供科学依据。

| Abstract: | Based on the observation data and GIS technique,through selecting the Hongze Lake ecosystem health evaluation indicators,calculating each indicator,determining the weights of each indicator and comprehensively calculating the ecosystem health index,the paper regionally evaluated the health situation of ecosystem in Hongze Lake.The results showed that there was different ecosystem health in different area in Hongze Lake.The ecosystem health of northwest part near the bank was better than that of center part ... |
