Abstract:
Guangdong Haifeng Avian Provincial Nature Reserve is a typical representative of coastal wetlands in subtropical regions of southern China, and it plays an important role in material production, environmental regulation, humanistic society and so on. Based on the comprehensive analysis of the present situation of Hai- feng wetlands, this paper used the ecological economic value assessment method, such as market value method, field survey method, benefit transfer method, shadow project method, afforestation cost method, carbon tax method, industrial oxygen generation method and re- placement cost method, etc. to classify the systematical- ly evaluation of the value and composition of Haifeng wetland ecosystem services. The results showed that the total value of wetland ecosystem service in Guang- dong Haifeng Avian Provincial Nature Reserve in 2013 was 107.861×10 6 yuan with an average value of 1.69 yuan·m -2 . The greatest among the indexes was biolog- ical diversity maintenance, accounting for 44.67% of the total value, and followed by recreation, food supply service, climate regulation, water purification, nutrient accumulation, carbon sequestration, water supply, sci- entific research, atmospheric constituent regulation, and raw material supply.
