摘要:
以石砭峪水库为研究对象,2011年7月至2012年7月对水库上游来水、库区及放水水质进行定期监测,分析了水库氮(N)、磷(P)营养盐的季节性变化规律,同时结合现场模拟实验对水库N、P营养盐收支状况做了相关研究.结果表明:石砭峪水库N、P含量呈现明显的季节性变化,表现为丰水期>平水期>枯水期;总氮(TN)和总磷(TP)年均值分别为2.65mg/L和0.04mg/L,较高的N、P含量导致水库浮游植物在适宜条件下大量繁殖,水库供水水质下降;水库TN、TP年输入量分别为226.50t和4.38t,年输出量分别为218.11t和4.31t,年滞留量分别为49.87t和1.07t;水库TN、TP输入负荷大小顺序是上游入流>库区周边地表径流>水库沉积物释放>大气沉降;水库TN和TP的年均沉积量分别为41.48t和1.00t;水库沉积物的TN、TP年释放量分别为7.29t和0.33t,对藻类生长繁殖的作用不可忽略
Abstract:
Based on the data monitored from Jul.2011to Jul.2012in Shibianyu Reservoir, the seasonal variation of nitrogen(N), phosphorus(P) nutrition were discussed and the simulating experiment were setup to analyse the budget of N, P. Results indicate that those parameters seasonal changes are obvious and their concentrations in abundant water period are much higher than in low water period. The average concentration of TN,TP per year are respectively 2.65mg/L and 0.04mg/L, and high concentration of TN and TP might bring algal bloom if the reservoir has fitting condition, which will endanger the water supply. The yearly input of TN,TP respectively amount to 226.50tand 4.38t,and output are respectively 218.11tand 4.31t,and the retention reach respectively 49.87tand 1.07t.The input from input water is the largest, input from land runoff is next to the largest, others are reservoir sediments and atmospheric deposition. TN, TP that settled down on the river floor per year are respectively 41.48tand 1.00t;The release of TN and TP in sediment of reservoir respectively amount of 7.29tand 0.33tand its contribution to algal bloom is important
