广西壮族自治区森林生态系统服务功能研究

Research on forest ecosystem services in Guangxi Zhuang Autonomous Region

利用广西2009年二次资源调查数据和森林生态站长期、连续观测数据及社会公共数据,采用森林生态系统服务功能评估规范(LY/T1721-2008),评估了广西森林生态系统服务功能的总价值。结果表明:广西森林生态系统服务功能总价值为8388.93亿元/每年,每公顷森林提供的价值平均为6.070万元/每年,7项服务功能的价值量排序:涵养水源>固碳制氧>保护生物多样性>净化大气环境>保育土壤>林木营养积累>森林游憩。不同林分类型由大到小的顺序为软阔类(37.86%)>松类(14.79%)>桉树(12.07%)>杉木(10.61%)>石山灌木林(7.71%)>灌木经济林(3.60%)>栎类(3.25%)>硬阔类(2.98%)>乔木经济林(2.69%)>竹林(2.55%)>土山灌木林(1.88%)>红树林(0.02%)。研究结果可为广西生态环境保护和核算绿色GDP以及森林资源的生态价值量化提供科学依据。

Abstract： This paper assessed the economic value of forest ecosystem services of Guangxi Zhuang Autonomous Region on the basis of the forest resource of Guangxi Zhuang Autonomous Region in 2009 ,the data of long term observation of Forest Ecosystem Research Station and the data of social commonality,adopting Specifications for Assessment of Forest Ecosystem Services in China （LY/T1721-2008）. The results showed that the annual average value of the Guangxi Zhuan_g Autonomous Region forest ecosystem services was 838. 893 billion yuan. The annual mean value of forest eco- system services was 607. 0 hundred yuan per hectare. The sort of 7 service functions value：water supply〉carbon fixedand oxygen released〉biodiversity conservation〉environmental purification〉soil conservation〉forest nutrition storage 〉 forest tourism. The descending order of different forest type was softwood forests（37. 86 %）〉pine forests（14. 79 %） eucalyptus forests （ 12. 07 %）〉 fir forests （ 10. 61%） 〉 shishan shrubbery （ 7. 71%） 〉 shrubbery economic forests （3. 60%）〉oak forests （3. 25%）〉 broad leaf forests （2. 98%） 〉arbor economic forests （2. 69%） 〉 bamboo forests （2. 55 %）〉tushan shrubbery（1.88%）〉mangrove（0. 02 %）. Provide a scientific basis for the protection of ecological en- vironment and accounting of green GDP,as well as quantifying the ecological value of forest resources.
