A Study of the Water Balance of Lake Balkhash

Lake Balkhash basin in Central Asia is a unique landscape ecosystem;Lake Balkhash is the core of the basin.The water level of it is regarded as key indicator of Lake Balkhash basin ecosystems and its protection effect,always attracting worldwide attention.Study of Lake Balkhash water balance has great theoretical and practical significance for determining reasonably the ecosystem protection goals and conservation measures.Based on deeply understanding the factors that control the water system and water level of the lake,a water balance model of the lake is developed.Then the water balance changing process in the lake from 1936 to 2008 is presented in the bases of multi-source data and prophase research result,enable to analyze the income of the lake(surface runoff into the lake,precipitation upon the lake,groundwater into the lake) and expenditure of the lake(evaporation from lake surface,water consumption in delta),and to discuss the water amount into the lake from the Ili River delta,the groundwater interaction between the lake and lakeshore surrounding the lake,the effect of human activities and climate change on water balance of the lake,in order to provide measures to protect the lake and the ecosystem around Lake Balkhash.
