摘要
农业面源磷污染是导致水环境的恶化重要原因之一。贵州是全国唯一没有平原支撑的强烈岩溶化高原山区省份,水土流失引起的磷素流失严重。对贵州农业土壤磷素含量变化、磷素流失特征进行了总结,描述了磷素流失对环境质量的影响,提出了防治贵州农业土壤磷素流失的技术措施。
The phosphorus pollution from the overuse of fertilizers and pesticides in rural area is one of important reasons to result in deterioration of water environment.The phosphorus loss caused by soil erosion is relatively serious in Guizhou because of its sole intense karst plateau mountainous province without the plain support in China.The paper summaries the variation condition of phosphorus content in arable soils and its phosphorus loss characteristic,analyzes the effect of phosphorus loss on environmental quality and puts forward the technological measures to control phosphorus loss in arable soils in Guizhou.
