摘要: 生态系统服务功能是指生态系统与生态过程所形成及所维持的人类赖以生存的自然环境条件与效用.最新研究表明,生态系统服务功能包括生态系统产品、生态调节功能、生命支持功能与社会文化功能.对生态调节功能的认识与评价是区域生态环境保护与资源开发的基础,并已成为当前区域生态评价与生态规划的前沿课题.以海南岛为例,探讨了基于生态系统结构与过程的生态调节功能评价方法.在研究中,将海南生态系统类型划分为13类,分析、评价了海南岛各类生态系统在水源涵养、水土保持、营养物质循环、固碳、防风固沙等方面的生态调节功能及其生态经济价值,以及生态系统提供产品的价值.研究表明,2002年海南岛生态系统所提供的生态调节功能的价值为2 035.88×108~2 153.39×108元,而生态系统产品价值仅为254.06×108元,生态调节功能价值是其产品价值的8倍多.

Abstract: Ecosystem services imply the natural environmental conditions on which human life relies for existence,and their effectiveness formed and sustained by ecosystem and its ecological processes.In newly research reports,they were divided into four groups,i.e.,provisioning services,regulation services,cultural services,and supporting services.To assess and valuate ecosystem services is the foundation of regional environmental reserve and development.Taking Hainan Island as an example and based on the structure and processes of natural ecosystem,this paper discussed the proper methods for regulation services assessment.The ecosystems were classified into 13 types including valley rain forest,mountainous rain forest,tropical monsoon forest,mountainous coppice forest,mountainous evergreen forest,tropical coniferous forest,shrubs,plantation,timber forest,windbreak forest,mangrove,savanna,and cropland,and then,the regulation services and their economic values of Hainan Island ecosystem were assessed and evaluated by terms of water-holding,soil conservancy,nutrient cycle,C fixation,and windbreak function.The economic value of the regulation services of Hainan Island ecosystem was estimated as 2035.88×108~2153.39×108 RMB yuan,8 times higher to its provisioning services (wood and agricultural products) which were estimated as only 254.06×108 RMB yuan.The result implied that ecosystem regulation services played an even more important role in the sustainable development of society and economy in Hainan Island.

Key words: Ecosystem services, Ecological regulation services, Hainan Island
