摘要
从涵养水源、保育土壤、固碳释氧、累积营养物质、净化大气环境、森林防护、生物多样性保护和森林游憩8个方面构建了昌江县森林生态效益评价体系,利用市场价值法、影子工程法等对其进行评估。结果表明:1)昌江县生态公益林生态效益高达15.56万元/hm2,在减灾固碳、保护生物多样性、促进生态产业发展方面作用显著;2)优势树种、龄组和起源对生态公益林的生态效益影响深远,影响森林生态效益的主要因素是人为干扰,在公益林建设中应根据生态公益林类型选择适宜的保护措施。
Taking the ecological public welfare forest in Changjiang county as the research object irom 8 as- pects of water conservation, soil conservation, carbon sequestration and oxygen release, accumulation of nutri- ents, purification of atmospheric environment, forest protection, biodiversity conservation and forest recreation to construct a evaluation system of forest ecological benefits. And the ecological benefits of public forest in Changjiang county were evaluated by using market value method and shadow engineering method. The results showed that： 1 ） ecological benefit of ecological public welfare forest as high as 155 600 yuan per hectare, and ecological public welfare forest plays an important role in reducing carbon sequestration, protecting biodiversity and promoting the development of ecological industry; 2） the dominant tree species, age group and origin of forest have a profound impact on the ecological benefits of ecological public welfare forest. Human disturbance is the main factor which affects forest ecological benefit profoundly, and the appropriate measures should be se- lected according to construct the ecological public welfare forest.
