摘要:

池州市是国家首个生态经济示范区，《中国21世纪议程》试点地之一，生态安徽建设试点市。基于LY/T1721 2008《森林生态系统生态服务价值评估规范》，采用实证研究、调查研究、文献研究等方法，估算了池州市森林生态系统生态服务价值。结果表明：2009年，池州市森林生态系统生态服务价值为443.30亿元，林果等实物产品价值为168.97亿元，生态服务价值是实物生产价值的2.62倍。各项生态服务功能价值大小顺序为：涵养水源＞固碳释氧＞生物多样性保护＞净化大气环境＞保育土壤＞森林游憩＞森林防护＞积累营养物质。可为池州市制定生态立市发展战略，走可持续发展之路提供理论依据和数据支撑，也可增强人们对森林资源保护的自觉性和主动性。

Abstract:

Chizhou City is the first national ecological economy demonstration and the pilot of the “China Agenda 21 Century”. Based on LY/T1721 2008 “The Assessment Standard of Forest Ecosystem Service Value” and the data provided by various governmental agencies of Chizhou，this paper estimated the forest ecosystem service value of Chizhou by the methods，such as empirical study，literature study and willing investigation. The results suggested that，in 2009，the forest ecosystem service value and the forest fruit production value of Chizhou were 443.30×108 Yuan and 16897×108 Yuan，respectively. The ecosystem service value was 2.62 times as much as the real value of production. The values of different ecosystem services arranged as follows:storage and retention of water＞fixing carbon and releasing oxygen＞biodiversity conservation＞air cleaning capacity＞soil conservation＞forest recreation＞forest protective efficiency＞nutrient accumulation. The valuation can not only provide theoradic evidence and statistic sustain for Chizhou sustainable development，but also enhance people’s forest protection consciousness.
