摘　　要：气温和降水是最重要的气候要素,与人们的生产、生活联系也最为紧密。通过对塔克拉玛干沙漠周边地区9个气象站34年逐月气温、降水资料分析研究,发现该地区暖季气温和降水有明显的上升趋势。暖季气温增加了约0.30℃,暖季对年气温变化的影响不如冷季大。暖季降水量约增加了7.30mm,暖季降水暖季降水量占全年降水量的82.96%,决定了年降水变化趋势。暖季气温对降水存在明显的逆动响应关系。Temperature and precipitation are the most important climate factors for their very good correlation with people＇s production and life. Data from the temperature and precipitation log provided by the 9 local stations around 1000m a.s.l. surrounding Taklimakan Desert have shown obvious climbing trends with temperature 0.30℃ and precipitation 7.30mm added. The affection of warm season on year＇s temperature is not so big as cold season and precipitation in warm season mainly decided the temperature trend of the year accounting for 82.96% of the year＇s precipitation. Temperature showed a negative correlation with precipitation in warm season.
