Study on the Environmental Management of Watershed Distinction

According to requirements of the natural and economic laws, the environmental management of watershed distinction is inevitable for improvement of watershed environmental management effect. In the paper, the Nine-division Principle is set forth, i.e. division by watershed, area, sequence, stage, type, grade, duty, right and policy through analysis of watershed distinction management in system theory and behavior economics, and of regional sub-characteristics of watershed in geographical elements, functions and economic developments. Under the guide of Nine-division principle, the idea on the environmental management of watershed distinction is reflected and implemented smoothly by dividing watershed environmental and economical function region, ways of optimizing the watershed environmental management, and creating conditions for implementation of environmental management of watershed distinction.
