摘　　要：采用降水径流与降水量相关法,和冰水径流模数法推算了乌鲁木齐河大西沟小冰期(盛)以来的径流变化。结果表明,大西沟的径流量在不断减少,其中的冰水径流量减少更大.The runoff variations were analysed by a correlation method of precipitation runoff and precipitation and a method of ice-melt water modulus. The results show that the total runoff, ice-melt water and precipitation runoffs had reduced by about 14.8%, 39.9% and 14.3% respectively, since Little Ice Age in the Daxigou-Urumqi River.It is inferred that the surface runoff in the Daxigou will continue decrease with a rise of air temperature in the future,and the surface runoff will reduce much more as compared with the precipitation.
