摘要:
为研究气候变化影响下的滁河流域降水量时空特征,基于滁河流域51个雨量站的2008—2020年逐日降水资料,应用Mann-Kendall法、线性回归法和累计距平法对滁河流域不同尺度降水量进行分析。结果表明:年降水量年际变化幅度较大,夏季降水占年降水50%,占比最大,冬季占比最小,年降水及春、秋、冬季降水均呈不显著上升趋势;年降水量分布总体上呈东南向西北递减,夏季和秋季降水量中游和下游明显多于上游,春季降水量上游和下游明显多于中游,冬季降水量则呈上游>中游>下游分布。
Abstract:
Based on the daily precipitation data of 51 rainfall stations in the Chuhe River basin from 2008 to 2020, the temporal and spatial distribution characteristics of precipitation in the Chuhe River basin under the influence of climate change were analysed by using Mann Kendall, linear regression and cumulative anomaly methods. The results show that the interannual variation range of annual precipitation is large. Summer precipitation accounts for 50% of annual precipitation, accounting for the largest proportion, while winter precipitation accounts for the smallest proportion. The annual and spring, autumn and winter precipitation showed no significant upward trend, and the annual precipitation changed greatly; The annual precipitation distribution is generally decreasing from southeast to northwest, while the quarterly precipitation presents different spatial distribution characteristics. The precipitation in the middle and lower reaches in summer and autumn is significantly more than that in the upper reaches, the precipitation in the upper and lower reaches in spring is significantly more than that in the middle reaches, and the precipitation in winter presents the distribution pattern of upper reaches>middle reaches>lower reaches.
