摘要研究了2002~2019年嘉陵江北碚断面径流量、悬浮泥沙(SS)浓度与输沙量、磷浓度与通量[分总磷(TP)、溶解态磷(DP)、颗粒态磷(PP)]年际变化及水期特征,基于河流基流分割原理对磷的来源进行了解析.结果表明,(1)2002~2019年,嘉陵江悬浮泥沙浓度和输沙量年际波动巨大,最大年输沙量是最小年输沙量的20倍以上.(2)18a间嘉陵江北碚断面总磷浓度年均值在0.058~0.139mg/L范围内波动,其多年平均值为0.098mg/L.2002~2013年,TP和PP浓度表现为丰水期>平、枯水期,之后有的年份表现为丰水期>平、枯水期,有的年份则表现为丰水期<平、枯水期.(3)18a间DP浓度总体呈先上升(2002~2016年)后下降趋势(2016~2019年),尤以平、枯水期最为显著.(4)18a间TP和PP通量年际波动巨大,TP年通量最大值(2.280万t/a,2005年)是最小值(0.399万t/a,2006年)的6.7倍.水量、沙量、TP通量和PP通量表现为一定程度的“水、沙、磷”同步效应,而且丰水期最强,枯水期最弱.(5)水期之间对比,丰水期TP、PP和DP通量远大于平、枯水期.TP、PP和DP丰水期通量在年度通量中的平均占比分别为73.5%、77.5%和64.9%.(6)面源磷负荷年际波动远大于点源磷负荷,TP总负荷的年际变化趋势取决于面源磷负荷趋势.除2006年外,其他年份面源负荷在总负荷中占绝对优势,按年度计算,面源负荷平均占82.5%,按丰水期计算,面源负荷平均占90.8%.面源年度负荷主要来自于丰水期(平均81.2%).

Abstract：The interannual variation and seasonality of runoff, and the concentration and flux of suspended sediment (SS) and phosphorus (P) (including total phosphorus (TP), dissolved phosphorus (DP), and particulate phosphorus (PP)) at Beibei section in the Jialing River were studied during 2002 through 2019. Based on the principle of river base flow segmentation, P loads were apportioned in terms of point and non-point sources. The results show that: (1) From 2002 to 2019, SS concentration and flux fluctuated greatly, and the maximum annual flux was greater over 20 times than the minimum. (2)The average concentration of TP in the whole period was 0.098mg/L with an annual average concentration ranging 0.058~0.139mg/L. During 2002~2013, concentrations of TP and PP were higher in the wet season than those in the even and dry seasons. During 2014~2019, some years saw the same pattern as during 2002~2013, while others saw the opposite direction. (3)DP concentrations increased first (2002~2016) and then decreased (2016~2019) at large. (4) The TP and PP fluxes showed significant interannual fluctuation in 18 years, and the maximum TP flux (22800t/a, 2005) was 5.7 times higher than the minimum (3990t/a, 2006). The water discharge, sediment discharge, and TP and PP flux exhibited a certain degree of synchronous effect in interannual trend, especially in the wet season. (5) TP, PP and DP fluxes in the wet season were much greater than those in the even and dry seasons, and they accounted for respectively 73.5%, 77.5%, and 64.9% of those in the whole year. (6) Loads from point sources displayed stronger interannual fluctuation than those from non-point sources, and the interannual trend of the total load depended on that from non-point sources. TP load from non-point sources contributed the absolute majority of the total load in every year except for 2006, and its percentage was averagely 82.5% for the whole year and 90.8% for the wet season. Also, The annual load from non-point sources mainly came from the wet season (averagely 81.2%).
