甘肃省白龙江林区主要森林类型生态服务功能价值评估

摘要

Based on the forest resources management survey data in Bailongjiang forest region and the long-term monitoring data by Bailongjiang Forest Eco-station, and according to the“Forest Ecosystem Services Assessment Standards”(LY/T1721-2008) promulgated by the State Forestry Administration of P.R.China, the ecosystem service function total values of five major forests in Bailongjiang forest region of Gansu province were evaluated. The results show that the total annual value of the ecosystem service functions of five types of forest was 30.3702 billion yuan (RMB), of which 13.3790 billion yuan for water conservation, 9.1667billion yuan for soil conservation, 4.4793 billion yuan for carbon fixation and oxygen released, 0.2627 billion yuan for nutrient accumulation, 1.5717 billion yuan for atmosphere environmental purification, 1.3797 billion yuan for species conservation, and 0.131 billion yuan for forest recreation. The findings will provide the basic data for forest resource account and green economic assessment in Gansu province.%采用甘肃省白龙江林区2010年度森林资源二类调查资料和白龙江森林生态站监测数据，依据国家林业局发布的《森林生态系统服务功能评估规范》（LY/T1721-2008），评价了甘肃省白龙江林区5种主要森林类型的生态服务功能总价值。结果表明：5种主要森林类型的生态系统服务功能价值每年为303.702亿元，其中涵养水源为133.790亿元，保育土壤为91.667亿元，固碳释氧为44.793亿元，积累营养物质为2.627亿元，净化大气环境为15.717亿元，生物多样性保护为13.797亿元，森林游憩为1.31亿元。研究结果将为甘肃省森林资源核算和绿色经济评价提供基础数据。
