【摘要】 青海高原位于青藏高原的东北部,区内有现代冰川2965条,冰川面积3675km2,冰储量2650×108m3。冰川面积占全国冰川总面积的6.19%,占西北冰川总面积的6.31%,是我国中低纬度地带山岳冰川较多的地区。青海高原山岳冰川具有稳定河川径流和调节作用,是青海高原水资源的重要组成部分。青海高原气候自20世纪80年代中后期出现由暖干向暖湿变化,对冰川生存和发展,提供了物质基础和环境条件。据预测到2050年青海高原温度上升2.2-2.6℃,降水量增加6~15%,青海高原现代冰川虽有退缩,但未来冰川不一定消失。更多还原

【Abstract】 Qinghai province locates in Northease of Tibetan plateau.In Qinghai plateau there are 2965 modernglaciers ,their areas are 3675km2and total ice storage capacity is 2 .65×1012m3,occupies 6 .19 %and 6 .31 %of total glacier areas in China andin northwest China respectively and Qinghai plateauis the regionwith more mountain glaciers in the middle latitudes in the World.The modern glaciers play ani mportantrole in regulating and stabilizing the runoff of the rivers and are the i mportant component of water re-sources in Qinghai .The existence and development of modern glaciers are closely related to the cli matechange ,local geographical environment ,ecosystems etc .The cli mate in Qinghai has changed from war-ming-drying type to warming-wettingtype since 1980’s ,which provides the material base andthe envi-ronment conditions for the development of modern glaciers in Qinghai .According to the report ,the cli-mate of Qinghai plateauis still changingto warming-wetting until to 2050 .The temperature will rise by2 .2 ~2 .6℃,the precipitation will increase by 6 %~15 %.In the paper ,the modern glacier resources inQinghai plateau are assessed,and their future is discussed.更多还原
