农田土壤流失对三沙湾水环境的影响研究
he Impact of Farmland Siol Loss to Water Environment in Sansha Bay
应用美国通用土壤流失方程（USLE），计算了三沙湾周边地区农田土壤的侵蚀量，并用0.3的输沙系数计算出每年由农田流入三沙湾的泥沙量为12.29万t。每年随土壤侵蚀进入湾内的N、P、CODcr的量分别占海洋对各污染物环境容量的10.18%、9.84%和1.05%，根据计算结果分析评价了土壤流失对湾内水环境的影响程度。
Using the Universal Soil Equationg(USLE),the amount of farmland soil loss around Sansha Bay was calculated. Using 0.3 of delivery ration,12.29×104 sediment into Sansha Bay was estimated.The amount of nitrogen, phosphorus and COD into Sansha Bay were also estimated,which respectively accounts for 10.18%,9.84%,1.05% of environment. capacity.Discussed the degree of impact to water environment in Sansha Bay.
