Title: Sensibility Analysis of the Runoff in the Headwater Regions of the Yellow River to Climate Change
Abstract: Sensibility of the runoff to climate change in the headwate regions of Yellow River is analyzed based on the measured data from the hydrological and weather stations in the regions from 1959 to 2008.The results indicate that variations of temperatures in the regions had an obvious relation with global warming and the temperatures in various subregions had been oscillating with a rising trend in the 50 a.However,the variations of precipitation in the regions were more intricate than temperatures because of the influences of geographical position and environment in various subregions,and the variations of annual precipitation in the main runoff-producing area had been oscillating with a decreasing trend in the same period.There is a remarkable nonlinear correlativity between runoff and precipitation and temperature in the regions.The runoff has decreased continually since the end of the 1980s,because of the precipitation decreasing in the main runoff-producing area in the region and temperature rising in the region.As a whole,the runoff in all subregions of the headwater regions of Yellow River is quite sensitive to precipitation variation.Furthermore,the runoff in the subregions above Jimai is more sensitive to the temperature variation than that in the other two subregions below Jimai.
