利用1982~2001年塔里木盆地冬季年平均气温、年总降水量和积雪面积资料，分析了冬季积雪面积对气候变化的响应。结果表明，整个流域SCA呈现缓慢下降的趋势。盆地北部、西部和南部的SCA对温度和降水的响应表明，降水变化对SCA的影响比温度的影响更大。SCA在2500ma.s.l以下缓慢增加，但在较高海拔地区下降。最低海拔地区易受降水影响，而最高海拔地区似乎主要受温度影响。2500~5000m的中部地带对气候变化最为敏感。20世纪90年代的降雪率和融雪率高于80年代。在冬季，SCA变化与降水变化呈正相关，与温度变化不相关。
Abstract Data of annual mean temperature, annual total precipitation and snow-cover area (SCA) in the winter season from 1982 to 2001 have been analyzed to examine the response of SCA to climate change in the Tarim basin, western China. The results show that over the entire basin SCA exhibits a slowly decreasing trend. The responses of SCA to temperature and precipitation in the northern, western and southern parts of the basin show a stronger effect of precipitation change on SCA than that of temperature. SCA has slowly increased below 2500ma.s.l., but has decreased at higher altitudes. The lowest-altitude zone was apt to be affected by precipitation, while the highest-altitude zone seems to have been influenced mainly by temperature. The middle zone from 2500 to 5000 m was the most sensitive to climate change. Snowfall and melt rates were higher in the 1990s than in the 1980s. In the winter season, SCA change was positively correlated with precipitation change but not with temperature change.
