| 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. |
