摘要
本文设计三种指标,使用43个站点1951—1982年的逐月和逐日降水资料分析得出:黄淮海及其附近地区降水资源的稳定性可分为南方型、北方型和西南部型三个类型。论述了各型和全年四个季节中降水资源稳定性的时空分布特征。指出多雨区和雨季中降水资源较为稳定,少雨区和旱季中雨量少且不稳定,以及太行山东麓平原地区是本区中降水资源最不稳定的地区。
Based on the 1951—1982 monthly and daily precipitation data at 43 stations,the three in-dices,i.e.mean anomaly percentage,mean interannual change percentage,and mean anomalies ofmean interval days with daily precipitation greater than 5,10 and 20 mm,are presented to studythe stability of precipitation resources in Huang-Huai-Hai river area and its surrounding area.Itcan be divided into three types:northern,southern,and southwestern.Meanwhile,the character-istics of the stability in temporal and spatial distributions are also discussed for each type and eachseason.
