摘要:农业生产的集约化程度越来越高,农业面源污染已经成了水体富营养化的主要来源之一,总磷超标问题比较突出,让水生态系统的安全出现严重威胁。目前多数研究都把重点放在工业点源或城市生活污水的磷控制上,还没系统探讨过农业面源里磷的迁移转化全流程机理,以及对应的高效拦截技术。本文主要做农业面源污染中总磷的超标机理研究,完成野外监测与模拟实验后,分析了土壤磷素积累、降雨径流冲刷及沟渠输移过程中磷的形态转化与释放规律,明确了不同水文条件下,溶解态磷与颗粒态磷各自的主导贡献。
关健词:农业面源污染;总磷超标;生态拦截技术

Abstract:With the increasing intensification of agricultural production, agricultural non-point source pollution has become one of the main sources of water eutrophication, and the issue of total phosphorus exceeding standards is particularly prominent, posing a serious threat to the safety of aquatic ecosystems. Currently, most research focuses on phosphorus control in industrial point sources or urban domestic sewage, and there has been no systematic exploration of the full-process mechanism of phosphorus migration and transformation in agricultural non-point sources, as well as corresponding efficient interception technologies. This paper mainly studies the mechanism of total phosphorus exceeding standards in agricultural non-point source pollution. After completing field monitoring and simulation experiments, it analyzes the transformation and release patterns of phosphorus forms during soil phosphorus accumulation, rainfall runoff scouring, and ditch transport processes, and clarifies the dominant contributions of dissolved phosphorus and particulate phosphorus under different hydrological conditions.
Keywords : agricultural non-point source pollution;total phosphorus exceeding standards;ecological interception technology
