| 中文摘要: |
| 基于 2023 年云南省原始森林资源调查数据,依据《森林生态系统服务功能评估规范》,采用物质量与价值量相结合的方法,从涵养水源、保育土壤、固碳释氧、积累营养物质、净化大气环境和生物多样性保护6 个方面,对云南省原始森林生态服务功能价值进行系统评估。 结果表明,云南省原始森林总面积为247.78 万hm2
,生态服务功能总价值为3 176.67 亿元/a,相当于全省2023年
GDP的10.58%。 其中,生物多样性保护价值(1 415.21 亿元,44.55%)、涵养水源价值(920.33 亿
元,28.97%)和保育土壤价值(588.56 亿元,18.53%)贡献最为显著。云南省原始森林单位面积价值为12.82 万元/hm2
,是全国森林生态服务功能平均值的 3.0倍,空间分布上呈现明显区域差异,滇西北地区价值总量最大,南部边境地区单位面积价值最高。 |
| 英文摘要: |
| Based on the 2023 survey data of primary forest resources in Yunnan Province and following
the Specifications for Assessment of Forest Ecosystem Services (LY/ T 1721—2008), this study systematically evaluated the ecological services value of primary forests in Yunnan Province using a combination of
physical quantities and value-based measurement methods. The assessment covered six aspects: water
conservation, soil preservation, carbon sequestration and oxygen release, nutrient accumulation, atmospheric environment purification, and biodiversity conservation. The results showed that the total area of
primary forests in Yunnan Province was 2.477 8 million hm2
, with an annual ecological service value of
317.667 billion yuan, accounting for 10.58% of the province′s GDP in 2023. Among the services,
biodiversity conservation value (141. 521 billion yuan, 44.55%), water conservation value (92.033 bil-lion yuan, 28.97%), and soil preservation value (58.856 billion yuan, 18.53%) contributed most significantly. The value per unit area was 128 200 yuan / hm2, which was 3.0 times the national average for
forest ecological services. Spatially, the valuation showed distinct regional variations: the northwest Yunnan
exhibited the highest total value, while the southern border areas exhibited the highest value per unit area. |
