摘　　要：【目的】分析环塔里木盆地农业气候因子的变化特征与趋势。【方法】利用1951-2005年的逐月气候资料分析。【结果】在全球变暖的大气候背景下,过去55 a中环塔里木盆地年平均气温显著升高,增温速率在0.22℃/10 a以上。各季节及生长季平均气温都有所增加,冬季最大,达到0.5℃/10 a。冬季和秋季最高温增加均较明显。冬季、年平均和春季平均最低气温增加显著。生长季的平均、最高、最低气温增温速率都不明显。对降水量的分析结果表明,春季降水量、年降水量和生长季平均降水量有明显增加趋势。【结论】通过分析该地区农业气候变化特征,以期为有效管理区域农业、水资源,改善生态系统和实现可持续发展提供科学依据。【Objective and Method】Based on the monthly climatic data from 1951 to 2005,the changing characteristics and trend of agroclimatic elements in Tarim Basin were studied.【Result】Under the circumstances of global warming,during the past 55 years,the average annual temperature increased obviously and the warming speed was above 0.22℃/10a.The average air temperature in every season and in growing season increased slightly.The average temperature in winter increased with the biggest ratio,speed was 0.5℃/10a.The winter and autumn average maximum temperature increased with obvious trend.The winter,annual,and spring average minimum temperature increased with obvious trend.For average temperature,average minimum temperature and average maximum temperature in growing season,there was no obvious trend to increase or to decrease.The result of analyzing rainfall showed the rainfall of spring,annual rainfall and growing season average rainfall increased obviously.【Conclusion】The aim of analyzing the changing characteristics of agricultural climate in this area is for providing scientific basis for managing the region agriculture and the water resources effectively,and for improving the ecosystem and achieving sustainable development.
