江苏盐城滨海湿地是以保护丹顶鹤起重机和麋鹿为主要内容的两个国家级自然保护区，该地区滨海湿地的各个发展阶段都受到湿地开垦、不合理开发利用、水质恶化、本文分析了滨海湿地面临的多种生态压力，包括人口压力、社会经济压力、本文从资源环境压力、环境污染压力、资源环境压力、状态与响应之间的关系出发，以生态控制响应理论和可持续发展理论为基础，提出了滨海湿地生态系统健康发展的生态对策框架和相应措施。（1）生态保护区规划设计。确定核心区、缓冲区和实验区的优化配置，以确保CWY的保护目标明确，并将一些生物多样性热点转化为核心生态保护区。(2)生态工程。实施一批湿地相关项目（水禽湖、芦苇场、鱼塘等）。在缓冲区，为维持水禽池塘的反馈，获得巨大的经济效益;在生态旅游区，为保护湿地景观提供良好的补充。（3）生态系统管理：社区共管是自然保护区管理的一种新途径，社区居民可以从农业新技术的应用和社区发展项目的实施中受益，同时可以加强生物多样性的保护。
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.
