摘　　要：塔克拉玛干沙漠周边地区近40 a来年气温和年降水有明显的上升趋势,位于沙漠南端以西昆仑山冰雪融水和山区降水为补给的玉龙喀什河和喀拉喀什河出山径流理应上升,利用研究资料分析表明这两条河的出山径流存在下降的相反趋势,夏季温度是玉龙喀什河与喀拉喀什河径流量维持稳定的主导因子,而山区夏季降水量的减少则导致玉龙喀什河与喀拉喀什河年径流量呈现减少趋势。Temperature and precipitation of areas around Taklimakan desert showed an obvious rising trend in recent forty years. Runoff in fiver Yurunkax and Karakax which located in the south desert and recharged by snow and glaciers melt water and rainwater on west Kunlun mountain should be rising. Analyzing showed that runoff was in descending after processing data, and summer temperature was the key role for maintaining the runoff steady of river Yurunkax and Karakax ; summer precipitation on mountain area played an important role for the runoff decline of fiver Yurunkax and Karakax.
