摘要
以云南省内25个逐日气象站点资料为基础,统计了区域年、季降水量时间分布特征;并以各站点年季平均降水量为输入,在ArcGIS环境下对其空间分布特征展开分析。结果表明,该省年均降水量为1082.22±328.88 mm,季候分布差异大;空间分析结果表明,不同季候尺度上的降水量符合高斯、球面、指数、线性等多种拟合模型,其推断的降水空间格局呈现渐变性与地带性特点,区域年季降水空间分布不均衡,降水中心随季节变化。
Based on the data of 25 daily meteorological stations in Yunnan Province,the temporal distribution characteristics of regional annual and seasonal precipitation were counted;and the annual and quarterly average precipitation of each station was used as the input to analyze the spatial distribution characteristics in ArcGIS environment.The results show that the average annual precipitation in the province is 1082.22±328.88 mm,and the seasonal distribution varies greatly.The results of spatial analysis show that the precipitation on different climatic scales conforms to various fitting models such as Gaussian,spherical,exponential and linear.The inferred spatial pattern of precipitation presents gradual and zonal characteristics,the spatial distribution of regional annual precipitation is uneven,and the precipitation center changes with the seasons.
