Abstract The effective implementation of environmental law has taken on greater urgency in recent times. Behind the multitude of domestic and international environmental instruments sit generally accepted principles like the Polluter Pays Principle (PPP). The PPP can be seen to advance sustainable development, at least partly, by private operators internalizing the costs of their pollution. This article analyses the application of the PPP in Chinese environmental law by focusing on a case study of Yangtze River pollution in and around the central Chinese city of Wuhan. The authors find evidence of an increasing acceptance of the PPP at the local, regional and national levels in China. At each of these levels, attempts to improve water quality in the Yangtze appear to reflect an acceptance of the PPP’s main aims.

The river chief system (RCS) has been innovatively implemented in Wuxi, China since 2007 for the eutrophication control of Tai Lake. In 2016, RCS was eventually promoted throughout China to reinforce river and lake protection. The success of this new river management system is generally attributed to collaboration, accountability, and differentiation effects. This research takes Foshan in the Pearl River Delta region as a case study to examine the feasibility and weaknesses in the implementation of the RCS. Prior to the formal adoption of RCS, a coordinating organization for river improvement undertaking was established in Foshan to overcome fragmentation in water management. Compared with this practice, the new RCS can strengthen the collaboration of administrative authorities and establish a considerably sophisticated and effective management structure. Emphasis on evaluation and accountability mechanisms guarantees that management goals can be achieved. However, similar to the previous one, the new system remains a temporary management practice and its outcomes depend partially on the commitment and capability of each river chief. The imperfect evaluation and accountability mechanism also weaken its long-term effectiveness in improving river water quality. Therefore, some corresponding policy instruments are needed to ensure that RCS can be implemented smoothly.

Demonstration project attempted to restore the terrestrial habitats around wetlands and reduce the manganese (Mn) pollution of wetlands. Project had tested five kinds of trees for phytoremediation in terrestrial habitats, and designed Ecological interception system (EIS) to control the Mn pollution to wetlands. EIS was composed of the surface runoff collection system (SRCS) and the Treatment system (TS). SRCS composed of cobblestones, high-capacity adsorbent fillers, sands and plants. TS composed of three subsurface wetland units processing modules. The results show that: (1)New soil and base fertilizer applied in the plant pits can effectively improve plants survival rate; (2)Koelreuteria paniculata, Elaeocarpus sylvestris and Paulownia can be used for phytoremediation in terrestrial habitats; (3)Canna warszewiczii, Boehmeria, Thalia dealbata and other nine kinds plants in the EIS can absorb the Mn element effectively; (4)EIS can purify the water effectively. The complex project was based on the biological principles, ecological principles and biochemical effects which provides a reasonable ecological engineering model suitable for the restoration of polluted wetlands.
