摘要
Abstract
The ecological protection project at the Aibi Lake of transferring water from the Kashi River to the Jing River is studied to investigate the impacts of the water transfer project on the water environment of the Aibi Lake. which is a receiving water body and has a high salinity. Based on the development of the lD water quality model and 2D lake salinity forecast model, the variations of water quality in the water diversion river and water conveyance line are obtained before and after the water diversion,the variation patterns of the water salinity in the Aibi Lake with the extension of the water diversion are studied,and the spatial distribution of the dilution degree of fresh water on the lake salinity is determined with the planning level under the yearly assurance rate of 25%. Furthermore.the impacts of water diversion on the lake salinity under the normal flow and low flow years are studied. The results show that the types of water quality in the water diversion river and water conveyance line are similar before and after the implementation of the water diversion project; the functions of the river water quality do not decrease; the water salinity changes greatly near the estuary in 3d but remains stable after 3d, the dilution effects of fresh water on the lake salinity are insignificant with the area of dilution degrees of 20% and 10% near the estuary of lake,and the dilution effects of water diversion on the lake salinity are not apparent under the normal flow and low flow years.关键词
