Recent changes of glacier coverage and current state of glacier lake outburst flood in the central Asian mountains.

利用卫星资料和实地调查，对1970年以来中亚天山冰川和冰川湖泊的现状进行了评价。卫星数据显示，在过去的40年里，山区冰川已经缩小。天山冰川消融具有区域差异。冰川面积减少幅度最大的是年降水量大、山脉较低的天山外围山脉(Pskem区)。冰川湖泊也发育在外部山脉，大多数是在20世纪80年代以后出现的。在天山北部，由于频繁发生冰川流，现今冰川湖泊的数量与20世纪70年代持平。

The current states of glaciers and glacier lakes in the Tien Shan mountains of Central Asia since 1970 were evaluated using satellite data and field survey. Satellite data showed that mountain glaciers have shrunk in the last 40 years. The glacier reduction has regional differences among the Tien Shan. The large reduction of glacier area was the outer ranges (Pskem region) of Tien Shan which has large annual precipitation and lower mountain ranges. Glacier lakes have also developed in the outer ranges and most of them appeared since the 1980s. In the northern part of Tien Shan, the number of present glacier lakes reached the same as that in the 1970s as many GLOF occur frequently.
