Coastal Wetlands in Yancheng (CWY),Jiangsu Province consist of two national natural reserves characterized by protecting red crowned crane and elk.Each developmental stage of the coastal wetland in this area is under the strong influences of human activities such as wetlands reclamation,irrational exploitation,water quality degradation,etc.All of these aggravated the pressure imposed on the coastal wetland area.This paper analyzes multiple kinds of environmen tal pressure,including population pressure,socio economic pressure,irrational exploitation pressu re,environmental pollution pressure,to explore relationships among resource environmental pres sure,state and response;for the purpose of using ecological policies to turn the ecosystems of the coastal wetlands to a healthy state.Based on ecological cybernetic responses and sustainable development,a framework with relevant measures is proposed in this paper as follows:(1) Ecologi cal planning and design.To identify an optimal allocation of its core zones,buffer zones and experimental zones in order to assure a clear conservation target of CWY,and convert some biodiversity hotspots into a core ecological preserve area.(2) Ecological engineering.To implement a number of wetland related projects (waterfowl lake,reed farms,fish ponds,et al.)in the buffer zone for gaining great economic benefits to maintain feedbacks to waterfowl ponds and in the ecotourism zone serving as a good supplement to preserve wetlands landscape.(3)Ecosystem management.Community co management is a new approach to natural reserve management.Com munity residents can benefit from the application of new agricultural technology and implementation of community development programs.Meanwhile,the conservation of bio diversity can be strengthened.
