中文摘要非点源污染是生态环境建设中遇到的关键问题之一,本文以四川省盐亭农业生态试验站流域的地下水为例,通过设定降雨量参数,将降雨量与地下水非点源污染负荷联系起来,分别研究了地下水磷素与地下水氮素随降雨量的变化情况。研究发现两个研究区的TP、TN浓度与降雨量的相关性十分明显,相关系数R2分别为0.987、0.9475、0.9331和0.9018,而其他形态的氮和磷与降雨量的相关性并不明显;另外,研究发现地下水非点源TN污染主要是由于NO3-N浓度变化引起的,地下水非点源磷污染主要是由于颗粒态磷浓度变化引起的。
英文摘要The non-point source pollution is one of the key problems in the construction of ecological agriculture. This paper,based on the groundwater of the agriculture ecology station at Yanting City,Sichuan Province,contacted the non-point source pollution transport with groundwater through rainfall parameter method and studied the changing on phosphorus and nitrogen in groundwater with the rainfall duration,respectively. The results showed that,the relationship between rainfall and the transport concentration of TP and TN in two studied areas were prominent,and the correlative coefficient R2 were 0.987、0.947 5、0.933 1 and 0.901 8,respectively,but the relationship between rainfall and the other forms of nitrogen and phosphorus were not significantly. Moreover,the non-point source TN pollution in groundwater was mostly caused by the change in NO3-N concentration,and the non-point source P pollution in groundwater was mostly caused by the change in particle form of phosphorus.
