摘要
Based on the observed data of weather and runoff since 1960, the variation trend of climate and runoff, as the contribution of glacier meltwater runoff to the surface runoff and the response rule to the climate change, were analyzed quantitatively in the five major rivers-Aksu River, Weigan River, Yarkant River, Hotan River and Kriya River, by using the mathematical statistics method and the water balance model. The results show that: (1)Under the significance level at 0.01, the precipitation in the northern basin, as the temperature in all five basins showed a significant rising trend.(2)The surface runoff of the five major rivers showed a significant rising trend, which time was consistent with the time of abrupt temperature change, but lagged behind it slightly.(3)Glacier meltwater runoff increased with the rising temperature, and in drought years with little precipitation, it was much higher than the average level of the five basins, with the proportion 67.98%, 38.81%, 70.48%, 72.07% and 78.92% respectively. © 2022, The Editorial Board of Journal of Basic Science and Engineering.
