| 摘 要： | 利用1955－1997年陕西渭北旱塬地区5个县，市的年平均气温，年降水量和季平均气温，季降水量资料，对近43年来陕西 北地区降水量与气温间的相关性进行了分析研究，结果表明，本区全年，夏季，春季降水量与全年及夏季，春季的平均气温之间有极显著的相关性，温度越高，降水量越少，二者之间的关系可以用二次多项式回归方程量化表示，冬季降水量与冬季平均气温之间有显著相关性，降水随温度升高呈指数式减少。

| Abstract: | Based on the data of the annually mean air temperature and the annually precipitation, seasonal mean air temperature and seasonal precipitation from five stations in Weibei dry land of Shaanxi province , the correlation between precipitation and temperature have been analyzed of this region in recent 43 year. Results show that the precipitation of annual, summer and spring is decreasing very marked by the mean air temperature raised, and the relation between the precipitation and the temperature can be showed by quadratic polynomial regression equation in the region. The winter precipitation is marked decreasing by the winter mean air temperature raised with exponential correlation in the region. |
