云南铜壁关自然保护区森林生态系统服务功能价值评估

Evaluation of Forest Ecological Service Function in Tongbiguan Nature Reserve of Yunnan Province

云南铜壁关省级自然保护区位于我国西南末端,是我国西南生态安全屏障中的重要组成部分。文章以铜壁关自然保护区为研究对象,采用2019年年度出数、2018年森林资源二调、地方统计年鉴、前人在其他区域的研究成果以及地方实地调查数据等,结合ArcGIS软件,对保护区森林生态系统服务价值进行评估分析。结果表明,铜壁关自然保护区森林生态系统服务总价值为80.64亿元/a,单位面积价值约为15.61万元/hm^(2)·a,各分量价值大小为涵养水源>固碳释氧>生物多样性价值>保育土壤>净化大气>森林康养>林木养分固持>木材产品供给。

Tongbiguan Provincial Nature Reserve,located at the end of Southwest China,is an important part of ecological security barrier in Southwest China.This paper evaluated and analyzed the forest ecosystem service value of Tongbiguan Nature Reserve by using the producing annual national estimates of forest resources in 2019,the forest resource inventory and planning data in 2018,the local statistical yearbook,previous research results in other regions and local field survey data based on ArcGIS software.The results showed that the total value of forest ecosystem services in Tongbiguan Nature Reserve was 8.064 billion yuan/A,and the value per unit area was about 156100 yuan/hm^(2)·a,the value of each component was water conservation>carbon fixation and oxygen release>biodiversity value>soil conservation>air purification>forest therapy>forest nutrient retention>wood product supply.
