摘要
土壤磷素的农业非点源污染是导致水体污染的最主要的原因之一。通过分析广东省的土壤磷素状况。发现由于近20 a来的高强度施肥造成了磷在土壤中大量积累,使土壤磷素的流失风险和数量都大大增加,给水环境造成了严重的威胁。为了应对土壤磷素流失给环境带来的影响,根据广东省自身的情况,提出了相应的控制措施和治理对策。
Soil phosphorus as agricultural non-point source pollution is one of the main factors which lead to water pollution. By analyzing the status of soil phosphorus in Guangdong Province, we discovered that risk and quantity of soil phosphorus loss increase rapidly and it severely pollutes the aquatic environment. So we should adopt some control measures to reduce the environment pollution resulted from soil phosphorus loss.
