汤浦水库流域非点源污染的时空分布及情景分析
Temporal-spatial distribution of non-point source pollution and scenario simulation of Tangpu reservoir watershed
摘要
Abstract
In order to explore the temporal-spatial distribution of non-point source pollution of Tangpu reservoir watershed.The non-point pollution model is established based on SWAT (Soil and Water Assessment Tool)model.The model is first calibrated and then to be validated.The simulation result shows that in the reservoir watershed,the loss of sediment,organic nitrogen and organophosphorus related with precipitation occurring mainly in flood season.The non-point pollutions are mainly arising from the eastern and northern of the basin.The source shows the consistency in space.The contents of pollution are uneven in different lands.Maximum sediment load is agricultural land with Scenario analysis showing that farmer work and land use type have an effect on non-point source pollution load.These research results will provide a scientific basis for controlling non-point source pollution in Tangpu reservoir.关键词
