摘要:

利用1986-2015年辽宁省60个气象站逐日降雨量观测资料和1986-2015年美国国家环境预报中心/美国国家大气研究中心(National Centers for Environmental Prediction/National Center for Atmospheric Research,NCEP/NCAR)逐月全球的再分析资料,对辽宁省年径流总量控制率区域划分及其分区分布的差异进行分析。结果表明:辽宁省年径流总量控制率可以划分为Ⅱ区、Ⅲ区、Ⅳ区、Ⅴ区共4个区,比《海绵城市建设技术指南-低影响开发雨水系统构建》中辽宁省年径流总量控制率分区多1个Ⅴ区,且相同分区对应的空间分布差异明显;年平均降雨量对年径流总量控制率的分区趋势具有一定指示作用,总暴雨量占总降雨量的比例与年径流总量控制率的分区关系密切,辽宁省水汽输送的特征和地形地势是形成年径流总量控制率区域分布差异的内在成因。

Abstract:

Based on the daily rainfall observation data from 60 meteorological stations in Liaoning province and the monthly global reanalysis data of the NCEP/NCAR (the National Centers for Environmental Prediction/National Center for Atmospheric Research) from 1986 to 2015,the regional division of volume capture ratio of annual rainfall runoff and its spatial variation in Liaoning province were analyzed.Results show that the volume capture ratio of annual rainfall runoff in Liaoning province can be divided into II division,III division IV division,and V division.There is one more division-the V division,than those in the“Sponge Urban Construction Technology Guide-Low Impact Development of Rainfall System to Build”,and the spatial distribution for the same division of these two studies differs apparently.The proportion of total rainstorm in total rainfall is closely related to the regional division of volume capture ratio of annual rainfall runoff.The characteristics of water vapor transportation and topography in Liaoning province are the internal causes for the regional distribution differences of the division of volume capture ratio of annual rainfall runoff.

Key words: Sponge City, Volume capture ratio of annual rainfall, Design rainfall, Ratio of rainstorm amount to the total precipitation amount
