摘　　要：应用喀和铁路沿线9个气象站1961～2008年气温、降水资料,采用克里格插值、线性倾向率、Mor-let小波等方法,分析了气温和降水的时空、变化趋势及周期特征。结果表明:喀和铁路沿线各地平均气温分布不均匀,降水量主要表现为西段的喀什一带多于东段和田一带,且自西向东逐渐偏少;气温和降水变化倾向率均为正值,分别为0.243℃/10a、4.321mm/10a;年代际分布表现为20世纪60年代最低(少)、21世纪00年代最高(多);季节分布表现为夏季最高(多),其次为春季,冬季最低(少);气温具有准31、17、7～10、3～4年,降水有准18～20、10、3年的年代际和年际震荡周期。Using the data of temperature and precipitation from nine meteorological observation station along the Kashgar-Hotan railway during 1961～2008 and adopting methods of the kriging、linear tendency rate、Morlet wave,the space time、change trend and period characteristic of temperature and precipitation were analyzed,The sdudy indicated some conclusions as follow： the average temperature distribution along the Kashgar-Hotan railway is not even,the mainly performance of decline amount of water is that it is a lot more in west segment of Kashgar than in east segment of Hotan,and it is gradually partial to little from west to east;The change tendency rates of temperature and precipitation are respectively 0.243℃/10a、4.321mm/10a;interannual distribution performs that it is the lowest（little） in 60＇s in 20 centuries、the tallest（many） in 00＇s in 21 centuries;The season distribution performs that summer is the hight,spring is the second,and it is the lowest in winter;temperature has the annual and age fluctuation period of 31 years、17 years、7～10 years and 3～4 years;precipitation has the annual and age fluctuation period of 18～20 years、10 years and 3 years.
