深圳福田红树林鸟类自然保护区生态服务功能价值评估

VALUATION OF ECOLOGICAL SERVICE FUNCTION OF FUTIAN MANGROVES AND BIRDS NATIONAL NATURE RESERVE,SHENZHEN

红树林湿地是我国热带、亚热带海岸湿地生态系统的重要类型之一,为人类提供多种生态服务功能.深圳福田红树林鸟类自然保护区以红树植物为主要植物群落,是中国惟一毗邻都市中心的红树林保护区.该研究运用市场价值法、替代市场法、旅游费用法等多种生态经济学方法,评估该保护区生态服务功能价值.研究结果显示,该保护区生态服务功能年均总价值约为4.417 9×108元,水质净化、栖息地和气体调节的价值在总价值中所占比重最大,是该保护区的核心服务功能.在对各项生态服务功能价值评估的基础之上,探讨了该保护区可持续发展和管理的策略.

Mangrove marsh is one of the most important types of wetland ecosystems along tropical and subtropical coastal areas.It supports a variety of natural resources and also provides a wide range of ecological services.These resources and services promote and sustain the economic activities in coastal areas.Futian mangroves and birds national nature reserve,Shenzhen is the smallest mangrove reserve located at the urban fringe in China.Different kinds of ecological economic methods,including marketing price method,substitute method and travel cost method,were used in the present research to evaluate the ecological service functions of the reserve.Our evaluation indicated that the annual total value of the ecological service functions was estimated at 441.79 million RMB.Among all the ecological service functions,water purification,habitat provision and gas regulation account for 39%,34% and 16% in total value,respectively,indicating that they are the core service functions of the reserve.Based on the results,some useful discussions have been put forward on the sustainable development and management of the reserve.
