Eco-Functional Regionalization and Protection of Eco-Functions in Heihe River Basin

According to the principles of integrity,dominance and comprehensiveness,the Heihe River basin is divided into three eco functional regions and nine eco functional sub regions by the method of overlapping coverage.The ecological characteristics and problems of each functional region and sub region are analyzed.On such a basis,measures are put forward for protecting ecology in each region and sub region,and strategies for protection and management of the ecology of Heihe River basin are proposed.
