摘　　要：基于《中华人民共和国林业行业标准(LY/T1721—2008)·森林生态系统服务功能评估规范》中的评估体系和评估方法,对威海市黑松海防林生态系统服务功能实物量和价值进行了评估。威海市100079.6hm2黑松海防林生态系统服务总价值为221.81×107元·a-1。其中,生物多样性保护价值所占比例最大,为45%;固碳、释氧和固土所占比例分别为24%、13%和10%;保肥、涵养水源、净化大气和森林保护功能价值所占比例都低于5%。由于资料不足或评估方法局限,导致净化大气和森林保护功能价值有所低估。Black pine forest ecosystem services were evaluated based on＂Specifications for assessment of forest ecosystem services in China＂（LY/T1721-2008） by China Forestry Administration.Total services value of black pine forest（100079.6 hm2） ecosystem at Weihai was 221.81 × 107yuan·a-1,among which,percentage of biodiversity protection value was the biggest,45% ;percentage of values for carbon fixation,oxygen generation and soil conservation were 24%,13% and 10% respectively;while values percentage for fertility maintenance,water conservation,air purification and forest protection were below 5%.The values for air purification and forest protection were underestimated due to the shortage of some data and the difficulty of evaluation methods.
