摘要: |
利用二维横向平均模型CE-QUAL-W2对山仔水库进行水力学和水质模拟,运用半年野外采样监测和室内实验分析数据校正模型主要参数并进行验证.选取2006年4月7日至6月7日的模型输出模拟结果,进一步运用李祚泳修正的营养状态指数法结合层次分析法对山仔水库出水水质进行富营养化评价,评价结果表明:山仔水库存在富营养化状况,其中5月12日营养状态指数最高,接近80;第一次大规模水华爆发从4月29日持续到6月初.通过设定三种情景(原始流量、降低水位、增加出流量)进行模拟分析表明,降低水位以及增加出流量都有利于改善对山仔水库下游取水口水质. |

Abstract: |
A two-dimensional, laterally averaged Model CE-QUAL-W2 was applied to the Shanzai Reservoir to simulate the hydrodynamics and water quality in the water column. The modeling effort was supported with data collected by fieldwork and experiments within half a year. Furthermore, the study made a water quality assessment of the eutrophication in the outlet of reservoir from Apr. 7th, 2006 to Jun 7th, 2006, using Trophic State Indexes (TSI) method and analytical hierarchy process(AHP). The result showed that, On May 12th, TSI was higher than the other days, almost reached 80; and the first big water blooms lasted from Apr. 29th to the beginning of June, 2006. The modeling result of three scenarios (keeping original flux, decreasing water level and increasing flux) indicated that decreasing water level and increasing flux could greatly improve the water quality of outlet. |
