| 摘 要： | 以北京市密云水库水体环境保护为出发点,以土壤-植物营养学原理和科学施肥理论为指导,根据作物所需畜禽粪尿肥的最大量,估算密云县各乡镇耕地的畜禽粪便最大负荷量,并与当地畜禽粪便实际负荷量进行比较,对各乡镇畜禽养殖规模进行潜在环境风险评价。结果表明:该流域中古北口、石城和番字牌3个乡镇风险最大,北庄较大。

| Abstract: | For the purpose of environment protection and practical agricultural production,the maximum admissible load of livestock manure of the farmland in the watershed of Miyun Reservoir was calculated based on the principles of soil-plant nutrition and the theory of scientific fertilization.By comparing the actual load of livestock manure with the maximum admissible load,environmental risk of livestock in each community within the watershed was evaluated.The results indicate that the pollution caused by livestock excrements threatens water quality of the watershed with different extents.Gubeikou,Shicheng and Fanzipai are exposed to the highest risk,and then Beizhuang follows. |
