摘要:
 以庆阳市25年生油松人工林为研究对象，在辖区正宁县、合水县、庆城县等7县选取21块样地进行调查，从油松人工林涵养水源、固碳放氧、生物多样性保护、森林生产力和游客游憩5种功能中筛选评价指标，结合调查数据和专家打分的方式确定各指标权重，构建生态服务功能评价指标体系。采用层次分析法和正态等距划分的方法，构建油松人工林生态服务功能评价模型，计算各样地的生态服务功能贡献率总分，将处于不同地区的油松林生态服务功能发挥划分为高效、较高效、中效、较低效和低效5个等级。确定了庆阳市油松人工林生态服务功能评价体系的14项评价指标，生态服务功能发挥重要程度为：水源涵养功能>固碳放氧功能>生物多样性保护功能>森林生产功能>游客游憩功能，油松人工林样地中生态服务功能发挥水平高效、较高效、中效、较低效和低效的样地所占比分别为0%、61.9%、38.1%、0%和0%，最好的地区是正宁县，最差的地区为镇原县。庆阳市油松人工林生态服务功能发挥比较一般，不同县区差异很大，造成的原因在于树种组成单一，林下植被盖度低，应采取相关经营措施。
Abstract:
 Based on the principles of scientific,systematic and operable,the ecological service function of 25year-old Pinus tabulaeformis plantations in Qingyang area was investigated,and an evaluation system was established to reveal the condition of ecological service function of P.tabulaeformis plantation in the area.Twenty one sample plots were surveyed in 7 counties,including Zhengning,Heshui,Qingcheng and so on.The indexes were chosen from the functions of water conservation,carbon fixation and oxygen release,biodiversity conservation and tourists recreation to assess forest ecological service function with the AHP and expert scoring methods.Forest ecological service function index model was employed to evaluate the health status of P.tabulaeformis plantations.Plantations were divided into 5 levels by their ecological service functions,level I: highest,II: higher,III: middle,IV: low,and V: lower.The established forest ecological service function assessment index system included 14 indexes.The order of the importance of ecological service functions was water conservation > carbon fixation and oxygen release > biodiversity protection > forest production > tourists recreation function.The percentages of the plantations with ecological service function level I to V were 0%,61.9%,38.1%,0%,and 0%.The best area was in Zhengning County,and worst in Zhenyuan Country.It indicated that the whole status of P.tabulaeformis plantations was in the middle level,significant differences existed among the areas within Qingyang.The main limiting factors were unitary structure of tree species,low understory coverage and forest in some areas,tending and management were needed.
