贫营养湖水环境承载力及对策研究--以抚仙湖为例

摘要

Oligotrophic lake has low concentrations of nitrogen ,phosphorus and other nutrients ,a low biological productivity with adequate dissolved oxygen.In this study,Fuxian Lake,as a typical oligotrophic lake among the nine plateau lakes in Yunnan,was selected as a case to explore the water environmental carrying capacity based on the generalized theory of water environmental carrying capacity and previous water carrying capacity calculated by EFDC model.An evaluation indicator system was built up for the Fuxian Lake.AHP method and cluster analysis were employed to execute a quantitative evaluation in order to reveal the current state of the water environmental carrying capacity of the Fuxian Lake.Many optimum Countermeasures and suggestions were put forward based on the identification of the main factors.%以云南省九大高原湖泊中贫营养湖典型代表-抚仙湖为例，以广义的水环境承载力理论为指导，基于前人EFDC模型计算的抚仙湖水环境容量，通过构建抚仙湖水环境承载力评价指标体系，采用层次分析法与聚类分析法结合的复合模型进行水环境承载力定量评价，揭示目前抚仙湖水环境承载力状况，通过评价分析识别主要影响因子，提出优化抚仙湖水环境承载力的对策建议。
