摘　　要：基于森林生态系统的长期、连续定位观测,采用辽宁省2006年森林资源清查数据,利用中华人民共和国林业行业标准《森林生态系统服务功能评估规范(LY/T1721—2008)》对辽宁省14个地市的主要植被类型生态系统功能进行了物质量和价值量评估.结果表明:2006年,辽宁省森林生态系统水源涵养、保育土壤、固碳制氧、营养物质积累、净化环境、生物多样性保护、森林游憩所提供的服务价值为2591.72亿元,分别为同年辽宁省林业总产值和同年辽宁省国内生产总值(GDP)的8.54倍和28.02%;涵养水源、生物多样性保护和固碳释氧价值合计占总服务价值的79.09%,是辽宁省森林主要的生态系统服务功能;经济林、灌木林的单位面积生态系统服务价值较小,但面积较大,其总生态系统服务价值不容忽视;冷杉林、水曲柳林、黄波罗林和核桃楸林是辽宁省典型地带性植被,具有较高的生物多样性价值;受气候等因素的影响,辽宁省西部森林面积及森林质量均低于东部.Based on the long-term located observation of forest ecosystem,and by using the 2006 forest resources inventory data of Liaoning Province and the forest industry standard of the People’s Republic of China（LY/T 1721-2008,specification for assessment of forest ecosystem services in China）,an evaluation was made on the material quantity and services value of main forest ecosystems in fourteen cities of Liaoning Province.In this province,the forest ecosystem services value supplied by water storage,soil conservation,C fixation,O_2 release,nutrients accumulation,environment purification,biodiversity conservation,and forest recreation in 2006 was 2591.72×108 yuan,which was 8.54 times of the forestry production value and 28.02% in the GDP of the province.The services value of water storage,biodiversity conservation,C fixation,and O_2 release occupied 79.09% of the total,being the main forest ecosystem services in the province.Economic forest and shrub had smaller per unit services value but larger area,and hence,their ecosystem services value should not be ignored.Abies fargesii forest,Phellodendron amurense forest,Juglans mandshurica forest,and Fraxinus mandshurica forest were the representative zonal vegetations in Liaoning Province,which had high value in biodiversity conservation.Under the effects of climate and other factors,the forest area and forest quality in west Liaoning were lower than those in east Liaoning.
