降水资源是水资源的重要基本单元。以纬度、地形、气候等因素影响，及区域内普遍干旱缺水等特点，根据滇中地区2000~2010年的降水资料，利用皮尔逊Ⅲ型曲线求出不同频率年降水量的累计频率，分析降水量年内的年际变化，进行年径流间的降水量分析。结果表明，滇中降水集中在5~8月，降水分布不均匀，可利用量与径流深变化幅度不大，说明流域降水分布分析是合理的。

Water resources is an important basic unit of water resources, according to the characteristics of Geology and geomorphology, climate change, spatial distribution, effective utilization of precipitation resource is different. The influence to the latitude, topography, climate and other factors, the characteristics of general drought region, Yunnan area analysis of available water resources, to improve the utilization of rainfall resources in Yunnan basin, has important significance for the rational allocation of water. According to theprecipitation data of 2000~2010 in Yunnan area , calculate the cumulative frequency of different frequency of precipitation by using Pearson type III curve , analysis of interannual variation of precipitation during the year analyzed the precipitation runoff?between. The results show that , the precipitation concentrated in May ~August months, the uneven distribution of precipitation, runoff amount and depth can change slightly, that is reasonable analysis of rainfall distribution.
