The Effects Of Climate Change On The Mountain Runoff Of Kaidu River

Kaidu river is the largest river which flows into Yanqi Basin, the river flows through Hejing,Yanqi and Bohu,and last flows into Bosten Lake. Kaidu river is the important industrial,agricultural production and urban residents living water source in it flow area. Kai River is the only perennial river supplies Bosten Lake, so Bosten Lake water changes are a major impact on water of kaidu. The People who lives in the southern border region their development of economic and life are seriously depends on the support of the Bosten Lake, research on a river of runoff has a vital importance for response of climate change and Projection of future changes of runoff. As the lower reaches of the river have a greater impact on people, so select source runoff of Dashankou Hydrological Station as a study.In this paper, are off to the upper reaches of the river Bayinbuluke elements of the climate and source runoff of Da Shankou runoff in analysis, research to the recent 40 years Bayinbuluke of temperature, precipitation and runoff of the Da Shankou Station changes and in the distribution of season. The results showed that Bayinbuluke neither winter nor annual average temperature has no significantly increased trend, but a higher rate of warming in summer. The 67.9 percent of rainfall in Summer, it is the main season of rainfall in Bayinbuluke. The mid-1980s is a period of at least precipitation ,and then began to gradually increase; since 1987 the runoff of Kaidu river is gradual increase ,it during to the good corresponding relationship existing between the average annual rainfall and average temperature in Bayinbuluke. the Climate changes have a direct impact on the river in a runoff changes.
