1993～2008年楚雄州森林生态系统服务功能价值评估与动态分析

Value Assessment and Dynamic Analysis of Forest Ecosystem Services in Chuxiong from 1993 to 2008

[目的]研究近20年楚雄州森林生态系统服务功能价值动态变化情况。[方法]利用1993、2000、2008年楚雄州森林资源清查数据,对生态服务功能进行评估,对1993-2008年楚雄州森林资源状况、服务功能价值变化进行动态分析。[结果]1993、2000、2008年森林生态系统服务功能总价值分别为650.04亿、743.88亿、914.31亿元。生物多样性保护和保育土壤价值最大,两者占比接近80%,而林木营养积累、涵养水源、供人们休闲游憩所占比重较低。[结论]楚雄州森林生态系统蕴含着巨大的有形和无形价值,对该地区的生态系统起着巨大的保护作用,森林生态系统的服务功能价值对地区发展具有重要意义。

[Objective] The aim was to study the dynamic change of forest ecosystem service value in Chuxiong Prefecture in recent 20 years. [ Method] By using forest resources inventory data in Chuxiong Prefecture in 1993, 2000 and 2008, ecological service function was evaluated, forest resource status and change of service function value during 1993-2008 was analyzed.[ Result] Total value of forest ecosystem service function in 1993, 2000 and 2008 were 65.004 billion yuan, 74.388 billion yuan, 91.431 billion yuan.Biodeversity protection and soil culti-vating value accounted for the biggest proportion （ close to 80%） , while forest nutrient accumulation, water conservation and recreation ac-counted for low proportion.[ Conclusion] The forest ecosystem in Chuxiong is of great tangible and intangible value, which plays an important role in protection of ecological system of the region, and the value of forest ecosystem services is of great significance to regional development.
