怒江州森林生态系统服务功能价值评估

Assessment of Forest Ecosystem Services Function Value in Nujiang Prefecture

采用国家行业标准,结合国内外通行的方法,测算了怒江州森林在涵养水源、保育土壤、固碳释氧、积累营养物质、净化大气环境、生物多样性保护等六类生态系统服务功能的物质量和价值量。怒江州森林生态系统服务功能总价值为1 120.83亿元/a,其中生物多样性保护价值为350.93亿元/a,占生态服务功能总价值的31.31%;保育土壤价值为338.03亿元/a,占30.16%;水源涵养价值为301.72亿元/a,占26.92%;固碳释氧价值为62.56亿元/a,占5.58%;净化大气环境价值为61.01亿元/a,占5.44%;积累营养物质价值为6.57亿元/a,占0.59%。单位面积森林生态系统服务功能价值为11.56万元/(hm2.a),相当于全国平均水平的2.09倍,云南省平均水平的1.71倍。

Taking national industry standards, and combined with domestic and foreign common methods, matter quality and value quality of forest ecosystem services function value in Nujiang Prefecture has been estimated from six aspects, such as water conservation, soil conservation, carbon sequestration and oxygen release, nutrients accumulation, atmospheric environment purification, biodiversity conservation etc. The total value of forest ecosystem service functions in Nujiang prefecture was up to 112. 083 billion yuan/a, among them biodiversity conservation value was 35. 093 billion yuan/a, accounting for 31.31% of the total value of ecosystem service functions; soil conservation value was 33. 803 billion yuan/a, accounting for 30.16% ; water conservation value was 30. 172 billion yuan/a, accounting for 26.92% ; carbon sequestration and oxygen release value were 6. 256 billion yuan/a, accounting for 5.58% ; atmospheric environmental purification value was 6. 101 billion yuan/a, accounting for 5.44% ; nutrients accumulation value was 657 million yuan/a, accounting for 0.59%. Forest ecosystem services value in unit area was 115600 yuan/（hm2. a）, which was 2.09 times equivalent to the national average, and 1.71 times to the average level of Yunnan Province.
