| 摘 要： | 采用分布式计算方法与NPP实测法,基于不同林分类型的生态服务功能,从物质量和价值量两个方面对江西省广丰县的森林生态服务功能价值进行了评估。结果表明,研究区森林生态效益总价值为41.56亿元,森林提供的生态价值平均为5.42万元/hm^2·年,涵养水源、固碳释氧和生物多样性保护价值合计达到总价值的88.02%。不同林分类型提供的生态效益价值排序为马尾松>灌木林>竹林>混交林>硬阔类>杉木>软阔类>国外松。单位面积不同林分类型提供的六项生态服务效益中,混交林提供的价值最大,为7.86万元/hm^2。

| Abstract: | The value of ecological services of different stand types in Guangfeng County,Jiangxi Province was evaluated from two aspects of substance amount and value by using the distributed calculation method and NPP measurement method.The results showed that the total value of forest ecological benefits in the study area was 4.156 billion yuan,and the average ecological value provided by the forest was 54200 yuan/(hm^2·a).The value of water conservation,carbon sequestration and oxygen release and biodiversity conservation reached 88.02% of the total value.The order of ecological value provided by different forest types was Pinus massoniana>shrub>bamboo>mixed forests>hard broad forests>Cunninghamia lanceolata>soft broad forests>Pinus elliottii.The value of ecological service provided by the mixed forests was up to 78600 yuan/hm^2,which was the largest among the six ecological services. |
