基于优化模型的抚仙湖营养物标准技术经济评估方法

在对美国水质标准经济分析研究的基础上，结合我国环境管理的实际情况，构建湖泊营养物标准的技术经济评估框架。计算标准建议值条件下的湖泊营养物容量及入量湖，得到削减量。通过不确定性优化模型对削减量进行分配，核算湖泊富营养化控制成本，并假设标准执行后，对流域经济造成的影响进行评估。将该方法应用于抚仙湖营养物标准的技术经济评估系统，结果表明，通过优化模型对削减量进行分配的削减成本较原规划低，通过构建的技术经济评估框架对该成本进行评估，标准执行后，对流域经济影响适中。

Optimization Model Based Technical-economic Evaluation Methodology of Nutrient Standards in the Lake of Fuxian

A technical-economic evaluation framework of lake nutrient standards was built based on a survey of economic analysis of water quality standards in the USA and the current environmental management system in China. Reduction quantity was obtained after calculating lake nutrient capacity and the input to the lake under the condition of suggested standard values. The reduction quantity was distributed by an uncertainty optimization model, and the control cost of eutrophication was accounted. The effects of the standard implementation on the lake basin economic development were evaluated. This evaluation method was applied to the technical-economic evaluation system of Fuxian Lake. The results demonstrated that the reduction cost of the schemes based on the optimized model was lower than that of the original planning of Fuxian Lake. The reduction cost was evaluated through the technical-economic evaluation framework, and the results showed that the impact on the lake basin economy was moderate if the standard was implemented.
