【摘要】 采用重庆地区34个气象观测站1971—2000年30 a平均月降水总量资料,以及重庆地区100 m×100 m DEM(D igital E levation Model)数据,对重庆地区降水空间分布进行研究。根据山地气候学原理,利用GIS(Geographical Information Systems)软件,分析降水空间分布的影响因子,建立平均月降水量空间估算模型,计算了平均月降水量的空间分布。结果表明:随着海拔高度的增加,降水量逐渐增加;各月降水量的最大值出现在东北山区;降水量的季节变化明显。更多还原

【Abstract】 Based on the 1971—2000 monthly precipitation data observed at 34 meteorological stations in the Chongqing region and the 100 m×100 m DEM(Digital Elevation Model) of Chongqing,the spatial distribution of precipitation of Chongqing was studied.In light of the principles of mountain climatology and using GIS(Geographical Information Systems) technology,the factors affecting the spatial distribution of precipitation were analyzed,the model to simulate the spatial distribution of averaged monthly precipitation was established,and the spatial distribution of averaged monthly precipitation was computed.The results show that the precipitation increased with the elevation,and the maximum value of monthly precipitation appeared in the northeast mountainous region;and the seasonal change of precipitation in Chongqing was distinctive.更多还原
