袁河流域水环境管理中控制单元的划分研究

Division of Control Units in Water Environmental Management in Yuanhe River Basin

以江西省袁河流域为例,介绍了控制单元划分的原则和方法,初步提出了控制单元的命名方法,同时还探讨了控制单元划分的尺度和等级问题。根据划分结果,袁河流域自上游而下共划分为5个控制单元,依次为芦溪控制单元、袁州区控制单元、仙女湖控制单元、新余控制单元和樟树控制单元,这样的划分模式既保证了小流域的完整性,又为袁河流域水质目标管理提供了实施单元。

With Yuanhe River Basin in Jiang＇xi Province as the example,the principle and method of control units division were introduced,and the nomenclature of control unit was proposed tentatively, in addition, the dimension and grade of control unit were also discussed. According to the results, five control units were divided along Yuanhe River from up-stream to down-stream, i. e. Luxi control unit, Yuanzhouqu control unit, Xiannvhu control unit,Xinyu control unit and Zhangshu control unit. The divided pattern of control unit in Yuanhe River Basin not only kept the intezritv of sub -basin.but also nrovided implementation unit for water quality target management.
