| 摘 要： | 在设置可控条件下的模拟生态系统中研究了旱耕赤红壤的氮、磷流失污染特征，结果显示：旱地土壤随地表流水流失的氮量远大于磷；环境条件一致的情况下，旱地氮、磷污染物输出浓度与作物生育期及施肥时间有关。并指出旱地氮、磷流失可能是珠江广州河段氮、磷含量较高的原因之一

| Abstract: | Systematic studies on the controlled block were conducted by using modeling experiment to reveal the basic characteristic, regularity N and P Losses from nonirrigated lateritic red earth fields in the suburbs of Guangzhou city.The total losses N is higher than that of P under the same conditions, the concentration of pollutants are related to the period of duration and the time of fertilizer application.It is possible to say that the losses of N and P is one of the reasons that result in a high concentration of N and P in the water body of Zhujiang River. |
