River eco-regionalization oriented by ecological restoration
生态修复目标导向的河流生态功能分区初探

Rapid socio-economic development would inevitably result in the damage of the river ecosystem at present and how to restore damaged river ecosystems to health status has become one of the important environmental issues urgent to be solved. Function zoning is the prerequisite for adaptive restoration, which could provide the scientific basis for the ecological restoration goal. In this work, function zoning of river was firstly compared with the main ecological regionalization, for both advantages and shortcomings. Based on the theories of ecological function regionalization, the conception of river restoration and eco-regionalization was discussed and the approach of eco-regionalization was studied theoretically. The Yongding River (Beijing segment) was selected as a study case and ecological function zoning including six river reaches was developed. The regulation index for ecological restoration of each reach was also proposed, which focused on ecological restoration of Yongding river in Beijing.
