【摘要】 利用新疆102个气象站点1990~2002年13年的月平均气温资料与DEM数据,运用SPSS统计软件,分别用逐步回归与多元回归方法分析研究了新疆月平均气温与经度、纬度、海拔高度的数学模型,通过验证,发现多元回归所建的模型模拟效果更好;然后根据多元回归模型应用GIS空间分析相关技术,生成月平均气温的空间分布栅格图.分析栅格图发现:新疆月平均气温在空间变化上呈现出与地形相一致的高低相间的分布形式,季节变化特点也较显著,在北疆部分地区有较明显的逆温现象,且逆温层呈不连续状态.更多还原

【Abstract】 Based on the data of air temperature obtained from 102 weather stations and DEM in Xingjiang,the mathematical models were developed by multiple variable regression and stepwise regression to study the relationship between monthly average air temperature and longitude、latitude、elevation.Model testing proved that the multiple regression models outperformed the stepwise regression models.Then based on GIS,the grid maps of monthly average were made by using the developed multiple regression models.It was found that the spatial distribution of the monthly average air temperature in Xinjiang appeared apparently consistent with that of sweel-and-swale topography and obviously seasonal variations,and there were apparent phenomena of temperature inversion and discontinuity of the strips of temperature inversion in the part of northern Xinjiang.更多还原
