摘  要:
三峡水库建成后,三峡库区生态系统服务价值将减少8852.90×104 ̄9708.35×104元。特殊生态环境有助于三峡库区农业非点源污染的发生,将对三峡水库水体安全造成极大威胁。建立不同土地利用类型下土壤养分流失模型是三峡库区农业非点源污染调控研究的核心,农业非点源污染防治的关键在于库区内土地利用结构的调整及拦截缓冲带的建立。

摘  要:
The value of ecosystem service in the Three Gorges Reservoir Area will be reduced to 8852.90×104~9708.35×104 Yuan after the construction of the Three-Gorges Project. The special eco-environments in the Three Gorges Reservoir Area help to the agricultural nonpoint source pollution, which will threaten the course of the Three Gorges Engineering. The under various types of land utilization is one of the most important tools for the researches of the agricultural nonpoint source pollution. The adjusting of land utilization structures and technology of the Conservation Buffer Strips are the cruxes of to Control agricultural nonpoint source pollution in the Three Gorges Reservoir Area.
