摘　　要：本文以新疆66个气象站1981-2010年气象资料为依据,利用地统计插值分析法,研究降水空间变化特征,并基于气温、气压、相对湿度等因素,分析对降雨空间变化的影响。结果表明:(1)新疆降雨分布具有显著空间变化,高纬度地区降雨量显著增加;(2)降水量与温度和湿度有较强的相关性,且与气温呈负相关关系,与气压相关性较弱。文章通过相关分析验证影响降雨分布的主要气象要素,并以此为依据提出降雨量最优计算公式,意为今后新疆局部区域降雨量预测提供理论依据。In this paper,the author,on basis of the meteorological data collected from 66 meteorological stations in xinjiang from the year 1981 to 2010,studied the spatial variation characteristics in precipitation by using interpolation method.Moreover,based on local temperature,pressure,relative humidity and so on factors,and analyzed their effects on spatial variation in precipitation.The results show that:1.There is remarkable spatial variation in rainfall distribution in Xinjiang,the rainfall remarkably increases in high latitude area.2.There is relative strong correlation between the precipitation and the temperature as well as the humidity,and the relationship between the precipitation and the temperature shows negative correlation,while the correlation between the precipitation and the pressure is weak.In this paper,the author also verified the main meteorological factors affecting on rainfall distribution by correlation analysis,and put forward accordingly the optimal calculation formula of rainfall,aiming at providing theoretical basis for the prediction of regional rainfall in Xinjiang in the future.
