摘要: 通过对2008~2009年武夷山国家风景名胜区流域8个监测点不同水期水质污染物指标的跟踪监测分析,研究流域地表水质的时空变化特征。结果表明,在空间上,流域干流自上游至下游污染物含量总体上表现为:上游下游中游的趋势;在季节上,枯水期NH3-N、TP、NO3--N浓度大于丰、平水期,主要与水量大小有关;TN、CODMn浓度表现为丰水期高于枯、平水期,与丰水季节降雨形成的非点源污染有关。该流域内水文特征环境因素、人类、农业活动及流域空间分布是造成溪流水质污染物特征的重要原因。

Abstract: Based on the data collected at 8 monitoring locations in Wuyishan National Park in different seasons from 2008 to 2009,the spatial and temporal characteristics of the surface water quality in the area were compiled.The results showed that the water qua1ity was significantly poorer in upstream;NH3-N,TP,NO3--N were significantly higher during dry seasons;and,TN and CODMn were higher in flood season,as the non-specific pollution could be induced by rain falls.The quality variations of the surface waters in the area were attributed to the geological and hydrological factors,human activities,as well as agricultural practices.
