摘要
本文利用焉耆盆地水盐动态长期观测和有关气象、水文等资料,对博斯腾湖作多年水盐平衡计算和盐污染过程分析。提出了控制盐污染的措施和淡化水质的可行方案。
The Yanji basin in which Bosten Lake is Located has an annual Precipitation 50~80mm,but its evaporation is 1800~2500mm and the ratio of evaporation to precipitation is beyond30. So the ecological environment is easily destroied. The Bosten Lake was a fresh water lakeoriginally. The human activies (mainly agriculture)aggravated the salinization and the salidityincreased from 0.38g/l in 1958 to 1.440g/l in 1975. The amount of flowing-in salt was more than the flowing-out salt during the 1960's.The lake water stage descreased gradually and the lake salidity inreased. It was not untill 1982that the annual average flowing-out salt exceeded flowing-in salt by 14.95×10~4 t. The lakesalidity got to steady during this time. This paper calculated the water-salt balance of Baster Lake by means of meteorologicaland hydrological materials of Yanji basin and obtained the processss of salt pollution ofBosten lake. Furthermore, it put forward a feasible management to control the salt pollutionand to purify the water of Bosten Lake.
