摘要
采用机会成本法、市场价格替代法、影子工程价格法等评估方法,对广东鼎湖山地区森林生态系统的涵养水源、保持土壤、净化空气、固定CO2、休闲游憩等服务功能进行了初步估算。得出该地区森林生态系统的涵养水源价值为6 617万元.-a 1,保持土壤价值为3 664.31万元.-a 1,固定CO2价值为252.90万元.-a 1,净化空气价值为436.62万元.-a 1,休闲游憩价值为31 369.00万元.-a 1。森林生态系统服务功能的总价值为4.234 0亿元.-a 1。
The ecosystem function of water conservation, soil conservation , air purification , CO2 fixation , tourism of Guangdong Dinghu Mountain were first evaluated by the methods of opportunity-cost ,market price ,shadow project price . The result indicated that the annual general forest ecosystem service value in this area amount to 42a. 40 million yuan/a, of which, 66. 17 million yuan/a for water conservation, 36. 64 million yuan/a for soil conservation, 4. 37 million yuan/a for air purification., 2. 53 million yuan/a for CO2, 313. 69 million yuan/a for tourism . This kind of evaluation is very important to arouse the con- sciousness of environment.
