This paper systematically summarizes and analyzes the advantages and disadvantages of the quantity and area of lakes in the western region and the resources of the lakes. It points out the environmental problems that the lakes in the western development will face and will emerge: (1) the lake level declines and the lake area shrinks; (2) the water quality becomes more and more serious ; ③The emergence and aggravation of lakes eutrophication; ④Source of disorderly exploitation of salt lake resources, deterioration of the ecological environment in the lake area; ⑤Stretching and the decrease of water level lead to the decrease of lake biological diversity. Analyzes the reasons of the ecological environment destruction in the lake and finally puts forward the countermeasures and suggestions of the lake environmental protection and the reasonable utilization of the resources so as to promote the sustainable utilization of the lake resources in the western area
