Analysis And Predict On Causes Of The Water Variation Of Ebinur Lake Area In Recent 20 Years

In order to survey the water of the Ebinur Lake, Xinjiang geography research institute of the Science Academy of China with the research group of Bole County anticipate surrounding the lake investigating the water amount situation in 1988. After the investigation, the river in Kuitun has not the surface water going into Ebinur from 70's to now. Ebinur every stream in the north , merely possess the a little flood water in the summer season to go into the sun dry little lake district , makes the little water area , and the water evaporates in briefly time to to be lost. Entry of the earth's surface water, originates profoundly from the Bortalanur and Jinghe River. Since the 80's 20 centuries, Ebinur's area continuees to broaden. The city proper ecology environment obvious improved. Compared with 60's and 70's, the area of a body of water area sharply lessens and the city environment seriously deteriorates to take shape the distinctive comparison. After the 60's, the effect inclines to steady that farming production changes to the area of the lake. River basin temperature and rainfall changes fluctuate to the surface of the lake, and the effect coming into being sensitively displays out. 80, 90 years the runoff into lake adds, and surface of the lake total is spreaded, and two changes keep unanimously[23]. Reached in the first end of the century and the beginning of the century, that Ebinur surface spreads correlation with the change of the river basin temperature and the rainfall alternation. It is the answer of the climate changes in the near future. However, the past few years mankind maneuver is yet very important. Distinct mankind's effect of the 60's, because of greatly opened up strategy implementation in the west in the near future, retreating the straw and limiting to pasture and usage of trickle irrigation, that each steps such as above and so on wholly shall benefit to the farming water amount to be saved, thereby add into the amount of flow in lake. In this fragment the reason that the area of Ebinur spreaded so quickly is about the change of wet and dry according the nature phenomen and have the strong relationship with the usage of water in the Vegetation. In recent years the area is covered in more rain, in the next two years it is still more rain. As the result the runoff of the lake will be more. But in the future 30...
