摘要：Due to the increasingly serious ecological degradation of river systems, research on how to restore damaged river ecosystems has become a high priority. Characterization of river functional regionalization is a prerequisite for adaptive ecological protection and management, which could provide a scientific basis for the river restoration and sustainable use of water resources. In this paper, the Songhua River in Harbin city is selected as a study site. The river functional assessment value is determined both in quality and quantity by the multiple-indices evaluation method. Then, the study area is divided into four parts in the longitudinal direction, consisting of an ecological protection area, a development and utilization area, a transition area, and an ecological restoration area. Furthermore, river regionalization can be established and analyzed in the horizontal, vertical and temporal perspectives to provide a reference for ecological restoration of the Songhua River. This paper proposes measures and contents for the regulation of river functional zoning.
