Practice of ecological remediation and restoration in plain river network -- a Case Study of Gehu Lake in Changzhou, China

Abstract

Abstract This study provides a design diagram which involves a series of pragmatic strategies for ecological remediation and restoration of plain river networks in the Yangtze River Delta. The design diagram is composed of two stages: the first concerns the reduction of pollutants, including those from non-point sources, point sources, and river sediments; the second, the restoration of the biological habitat, including the riparian zone and aquatic habitat. A case study of Gehu Lake was used as an example for the implementation of the suggested design diagram, and further suggestions were provided for the improvement of remediation work in plain river network areas. This research provides valuable insights into the methods of ecological restoration, and demonstrates the potential for multidisciplinary collaboration to help improve the environmental health of plain river networks.
