| 摘 要： | 根据祁连山区与河西走廊平原区有关水文气象台站的降水、气温和径流观测资料，分析了该区域近50a来气候变化的特征及其与全球气候变暖的关系。出山径流对气候变化的响应以及未来的变化趋势，结果表明，河西内陆干旱区的山区和走廊平原区近几十年来气温变化总的呈上升趋势，与全球增温存在着某种种度的一致性。但山区气温的变化幅度一般大于走廊平原区，其中祁连山中段温度升幅为最大。全球增温对河西内陆干旱区气候与出山径流的影响有着明显的地域性差异，受此影响影响，河西祁连山东部地区出山径流呈明显的下降趋势，中部地区出山径流的增加趋势不是十分明显，西部出山径流在山区降水量与气温同时上升的情况下，呈明显的上升趋势。 |

| Abstract: | Generally change on water resources is affected by human activities and climate change, but in the runoff forming areas in the high and intermediate mountains of Northwest China, it is governed mainly by climate change. The characteristics of climate change in the Hexi Region, an arid inland region, and their relation to global change are analyzed. So do the response of surface runoff to climate change and its future trend. The analyses are based on the observation of precipitation, air temperature and surface runoff in the Qilian Mountains and the Hexi Corridor. It is found that there are some obvious regional difference in the influences of global change on the weather and surface runoff in the Hexi Region, and surface runoff is of a greatly consanguineous relation with precipitation in the Qilian Mountains. However, in the western Hexi Region, air temperature change have some influences on the surface runoff. |
