为了探明东风西沙水库二级保护区内农业污染的情况，对保护区内不同农田利用类型（柑橘林、林下养鸡、粮田、菜地和水产养殖）的周围水体和土壤进行为期1年的氮、磷以及重金属含量的监测。结果表明：水体主要污染源为农业污染，在春夏季施肥时尤其严重，TN 为最严重的污染因子，全年超标；柑橘林和林下养鸡对水体污染贡献相对较高，最需要进行水体污染治理与防控；土壤质量基本符合二级保护区的要求，属于清洁、尚清洁状态，但在单项指标中柑橘林存在 Cu 超标的情况，全年处于污染警戒线状态，需要加强监测与防范。

In order to investigate the situation of agricultural pollution in the secondary reserves of Dongfeng Xisha reservoir,nitrogen,phosphorus and heavy metal content of surrounding water and soil of different farmland use types,including citrus forest,chicken breeding in forest,grain field,vegetable field and aquaculture,were mo-nitored for 1 year.The results showed that the major source of water pollution was agriculture pollution,and it was especially serious during spring and summer fertilization.TN was the most serious pollution factor,exceeding the standard throughout the year.Citrus forest and chicken breeding in forest contributed relatively high to water pol-lution,and the surrounding water needed to be protected and controlled from pollution.The soil soil quality basi-cally accorded with the secondary reserve requirements,and the situation of soil were clean and basically clean. However,soil of citrus forest had Cu exceeding the standards situation,and the soil quality was in the state of pol-lution alert throughout the year.Therefore,the monitoring and prevention of citrus forest soil should be strength-ened.
