Preliminary study on the maintenance of suitable water surface and water volume in Lake Taitmar
Conducting research on the appropriate size and water quantity maintenance of Lake Taitmar is of great significance for enhancing the efficiency of comprehensive water resources use in the basin,promoting the construction of ecological civilization in the Tarim River Basin,and realizing the harmony between human beings,water and ecology. Based on the hydro-logical and remote sensing monitoring data of the lower Tarim River,the paper constructed a model of the relationship between water surface area,vegetation coverage and vegetation area of the lake area by analyzing the characteristics of the water surface of the lake area and the ecological environment of the lake area,and solved the appropriate water surface size and ecological water volume of the lake area for realizing the goal of ecological protection. The results of the study show that:Based on historical data and ecological safety analyses,the appropriate water surface area size for Lake Taitmar ranges from 30 to 110 km2;When the water surface of Lake Taitmar is 110 km2,the corresponding vegetation area is 232 km2,and the vegetation coverage is 15. 1％,which can guarantee that the area and quality of the natural vegetation in the lake area will reach an excellent state,and at this time,the amount of water flowing into the lake from the Tarim River and the Chelsea River will be about 64 million m3;Considering the natural vegetation water demand,river base flow,groundwater replenishment and river evaporation,the ecological water demand of the lower Tarim River is 248 million m3/a under the condition of maintaining the hydraulic connection between the Tarim River and Lake Taitmar. The research results provide technical references for the ecological protection and restoration of the Tarim River Basin.
