摘要:
以浅水湖泊引清调水的目的为基础,结合生态水力学要求,兼考虑经济性因子,尝试性地建立了浅水湖泊调水方案评价指标体系,评价指标包括湖泊水质改善效果指标、水力条件指标和经济效益指标.以玄武湖调水模式为例,采用二维水质水量模型对玄武湖不同的引水规模、引水方式、引水口和出水口流量分配的引调水方案进行模拟计算,统计出各个评价指标的结果,综合分析评价出相对最优的引调水方案.该评价方法可推广到其它类似的浅水湖泊引清调水模式的评价中.

Abstract:
Based on the goal of water diversion for shallow lakes, taking the requirement of ecological hydraulics and economic factor into consideration, an attempt to establish an assessing indicator system for water diversion scheme of shallow lakes is put forward in this paper. The indicators are consisted of lake quality-improving indicators, hydraulic indicators and economic indicator. By the case of Lake Xuanwu, a 2-D water-quality model is adopted to simulate different schemes of water diversion for Lake Xuanwu with different flow flux, diversion mode, flow distribution of inlets, and flow distribution of outlets. Detailed assessing indicators of statistic results are obtained, and then the optimum water diversion scheme is assessed. The method can be applied to the assessment of water diversion on similar shallow lakes.
Key words:  Shallow lake  water diversion  assessing indicator  water-quality simulation  comprehensive assessment  Lake Xuanwu
