摘要:
根据1981~2004年连续24a的降雨、径流实测资料,采用数理统计方法分析了淮河流域上游迎河小流域的年降雨、径流变化特征及降雨与径流的关系.结果表明:迎河小流域降雨、径流的年际变异程度均较大,离差系数分别为0.28和0.45,显示出区域旱涝灾害出现机率大;降雨年内分配集中,汛期降雨量占年雨量82.1%;典型年份雨次的分析表明,流域次降雨雨型以均匀型为主;年降雨量同年径流量存在很好的线性正相关关系,可以用年降雨量对径流量进行预报;径流率与汛期雨量存在良好的线性正相关关系.
Abstract:
Based on the observation data from 1981 to 2004,characteristics of annual precipitation and runoff and their relationship in the typical watershed,Yinghe catchment,of the Huaihe river basin are systemically analyzed.The results show that there is a clear difference in annual precipitation and runoff flow year by year with 0.28 and 0.45 variance coefficient respectively.The rainfall amounts distribution centralizes in the flood-months,with 82.1% of the total occurring from May to October.Annual rainfall amount is a decisive factor of annual runoff.It implies that there is a rich opportunities of flood and drought disaster.The analysis of the typical year’s data shows that the even rainfall pattern is dominant.There is a very clear positive correlation relationship between annual precipitation and runoff flow,between runoff ratio and rainfall amount in the flood-months either.
