摘要:
东莞市国营清溪林场保存有典型的南亚热带常绿阔叶林, 是恢复、 重建南亚热带常绿阔叶林生 态系统的天然参照系统, 具有极为重要的经济和生态价值。 经过实地调研勘测, 构建了支持、 调节、 供 给、 文化这四大类服务功能组成的清溪林场森林生态产品价值核算指标体系, 从保育土壤、 林木养分固 持、 涵养水源、 固碳释氧、 净化大气、 生物多样性、 森林康养 7 类 18 项功能对林场下辖的 318 处小班进 行评估。 评估结果显示: 清溪林场森林生态系统生态产品价值为 7. 98E + 08 yuan / year。 其中固碳释氧 (3. 99E + 08 yuan / year) > 涵养水源 (2. 28E + 08 yuan / year) > 生物多样性 (7. 96E + 07 yuan / year) > 文化 服务 (5. 76E + 07 yuan / year) > 净化大气 (1. 61E + 07 yuan / year) > 土壤保育 (1. 36E + 07 yuan / year) > 林分养分固持 (4. 63E + 06 yuan / year), 整体来看, 清溪林场总生态价值量呈现为由南向北逐渐增高再降 低的变化趋势。

Abstract:
The state-owned Qingxi Forest Farm in Dongguan city preserves a typical southern subtropical evergreen broad-leaved forest, which is a natural reference system for restoring and reconstructing the ecosystem of the southern subtropical evergreen broad-leaved forest, and has extremely important economic and ecological value. After field investigation and survey, the value accounting index system of forest ecological products in Qingxi Forest Farm was constructed, which was composed of four types of service functions: support, regulation, supply and culture, and was evaluated from 18 functions in 7 categories: soil conservation, forest nutrient sequestration, water conservation, carbon sequestration and oxygen release, air purification, biodiversity, and forest health care. The assessment results show that the value of ecological products of forest ecosystem in Qingxi Forest Farm is 798 million yuan / year. Among them, carbon sequestration and oxygen release (399. 012 million yuan / year) > water conservation (227. 635 million yuan / year) > biodiversity (79. 595 million yuan / year) > cultural services (57. 631 million yuan / year) > air purification (16. 116 million yuan / year) > soil conservation (13. 62 million yuan / year) > nutrient sequestration (4. 637 million yuan / year). On the whole, the total ecological value of Qingxi Forest Farm gradually increased and then decreased from south to north.
