摘要: 基于1960 年以来中国天山各流域冰川面积变化的统计分析,系统地研究了中国天山冰川面积变化对气候的响应情况。结果表明,近50 年来中国天山冰川的面积缩小了11.5%,对研究时段统一化后发现面积年均退缩率为0.31% a-1。各流域冰川面积退缩速度存在一定差异,但冰川加速消融趋势明显。天山地区14 个气象站的气温与降水量倾向率平均值分别为0.34 oC·(10 a)-1与11 mm·(10 a)-1,气温在干季增幅大而在湿季增幅略小,降水量在干季增长缓慢而在湿季增长显著,这样的气候变化趋势有助于天山冰川的退缩。

Abstract: Based on the statistics of glacier area variation measured in Chinese Tianshan Mountains since 1960, the response of glacier area variation to climate change is discussed systematically. Results show that the total area of the glaciers has reduced by 11.5% in the past 50 years, which is a weighted percentage according to the glacier areas of 10 drainage areas divided by Glacier Inventory of China. The annual percentage of area changes (APAC) of glaciers in the Tianshan Mountains is 0.31% , after the standardization of the study period. According to the 14 meteorological stations in the Tianshan Mountains, both the temperature and precipitation display a marked increasing tendency from 1960 to 2009 with a rate of 0.34 ℃· (10 a)-1 and 11 mm·(10 a)-1, respectively. The temperature in dry seasons (from November to March) increases rapidly with a rate of 0.46 ℃·(10 a)-1, but the precipitation grows slowly at 2.3 mm·(10 a)-1; while the temperature in wet seasons (from April to October) grows with a rate of 0.25 ℃·(10 a)-1, but the precipitation increases at 8.7 mm·(10 a)-1.

Key words: Tianshan Mountains, glacier variation, glacier area, climate change
