摘　　要：从生态系统服务功能的概念入手,根据调查和研究,采用替代工程、市场价值等方法,从2个方面评价了鸡公山自然保护区森林生态系统服务功能的价值.结果表明,面积3000hm2的鸡公山自然保护区森林生态系统的生态服务功能价值70548.6万元·a-1,其中涵养水源价值8593.9万元·a-1,净化水质价值1265.3万元·a-1,保持土壤价值57754.1万元·a-1,固碳制氧价值2114.2万元·a-1,净化环境价值(吸收SO2量)26.1万元·a-1,游憩价值550万元·a-1,林产品价值245万元·a-1.Beginning with the concept of forest ecosystem services,and based on investigation and research,the authors adopted the eco-economy evaluation methods and classified the forest ecosystem service of Jigongshan National Nature Reserve into direct and indirect benefits. The results show that average annual forest ecosystem services benefits of Jigongshan National Nature Reserve ,which covers all area of 3 000 hm^2,add up to 70 548.6 million yuan·a^(-1)(Chinese RMB),of which,direct benefits makes up 1.13% and are about 7.95 million yuan,which includes about 5.5 million yuan incom form tourism,about 2.45 million yuan of the output of standing economic trees and forest products,whereas indirect benefits make up 98.87% and are 697.536 million yuan·a^(-1),which consist of 8 593.9 million (yuan·a^(-1)) of water-holding,about 1 265.3 million yuan·a^(-1) of water purification,and about 57 754 1 million yuan·a^(-1) of soil conservation,about 2 114.2 million yuan·a^(-1) of Carbon fixation and oxygen production,about 261 thousand yuan·a^(-1) of air purification.
