安徽省淮北市多年降雨变化及浅层地下水位响应研究OA
Study on long-term rainfall variation and shallow groundwater level response in Huaibei city,Anhui Province
为揭示地下水位对降雨、地下水开采及土地利用变化等因素的响应规律,采用小波分析、M-K趋势检验、滑动平均等方法对安徽省淮北市1956-2020 年降雨量及地下水自动监测数据进行对比分析.结果表明:淮北市年降雨量呈现多时空尺度变化特征,具有明显的周期性,以 36a和 6a最为显著,降雨量自 1956 年以来整体下降是地下水位总体降低的主要原因;地下水位变化可分为水位变化主要受降雨量控制,开采井分布造成了水位变化的空间差异,降雨量引起水位上升、地下水开…查看全部>>
To reveal the response patterns of groundwater levels to factors such as rainfall,groundwater extraction,and land use changes,methods such as wavelet analysis,M-K trend test,and moving average were used to comparatively analyze the rainfall and automatic groundwater monitoring data in Huaibei city,Anhui Province from 1956 to 2020.The results showed that the annual rainfall in Huaibei had the characteristics of multi-temporal and spatial scales with obvious p…查看全部>>
