摘要:
近几十年来,浅层湖泊、水库的水质在世界范围内受到关注. 本研究探究了黄村水库底层放空对水质的影响. 结果表明,底层放空前,方差分析结果显示,底层水和中层水之间Fe、P差异不显著; Mn和N的含量差异显著,底层水中的含量均显著高于中层水. 放空前后监测物的方差分析比较显示,水库底层水Fe、Mn、P、N差异均不显著; 水库中层水Fe、Mn、P差异均不显著,N的含量差异显著,放空后中层水N含量显著增加. 回归分析结果表明,水库中Fe和P含量随时间增加显著,Mn和N含量随时间增加不显著,但从长远变化趋势来看,水库中Mn和N含量呈增加趋势. 在放空洞排水过程中,Fe、Mn、P、N的自然增加率均大于减少率,表明放空洞排水不能抵消由外部因素带入水库的营养盐.
Abstract:
Water quality in shallow lakes has suffered worldwide in recent decades. This study explored the effect of the bottom water releasing of huangcun reservoir on water quality. The results showed that before the bottom water was released,the analysis of variance showed that there was no significant difference in Fe and P between the bottom water and the intermediate water. The concentration of Mn and N was significantly different,and the concentration of the bottom water was significantly higher than that of the intermediate water. The variance analysis of the detection substances before and after water releasing showed that the difference of Fe,Mn,P and N in the bottom water was not significant. The difference of Fe,Mn and P in the intermediate water was not significant while the difference of N concentration was significant. The results of regression analysis showed that the Fe and P contents increased significantly with time,while the Mn and N contents did not increase significantly with time,but from a long-term trend,the Mn and N contents showed an increasing trend. The natural increasing rate of Fe,Mn,P and N was greater than the decreasing rate in the process of water releasing,which showed that the water releasing cannot offset the nutrients brought into the reservoir by external factors.
