| 摘 要： | 含有氮磷元素的化合物是造成库区水质污染的主要物质之一。按照林外降雨、林内穿透降雨、树干径流、地表径流顺序,研究了密云库区主要水源涵养林树种对降雨中氮磷含量的影响,并对不同树种进行比较,对氮磷元素的变化趋势进行分析。结果表明：降雨、林内降雨、树干径流、地表径流中总氮含量都要远远大于总磷含量;油松、火炬能够增加降雨中总氮、总磷的含量。

| Abstract: | The compounds with N or P are one of main materials of water pollution in Miyun reservoir area.The effects of main tree species in water resource conservation forestry on N and P content in rainfall,forest throughfall,stem flow and ground flow were studied.Different tree species were compared.And the change trend of N and P elements were analyzed.The results would provide essential basis for the construction of water resource conservation forest in Miyun reservoir area.The results showed that total N conten... |
