摘　　要：为给长汀县水土保持林乔木树种选择提供科学依据,采用实地调查、专家评判、层次分析等方法构建水土保持林乔木树种评价指标体系并计算其权重,设置指标打分标准和乔木树种综合水土保持能力评价等级划分标准,对长汀县乔木树种水土保持综合能力进行了评价分析,结果为,长汀县策武、濯田、河田等最具代表性的地域共有种子植物96科251属599种植物,其中出现频率较高的乔木树种118种;长汀县乔木树种综合水土保持能力较好,评价等级共有Ш级,没有较差级别,其中Ⅰ级即水土保持能力优秀乔木有23种,Ⅱ级即水土保持能力良好乔木74种,Ш级即水土保持能力一般乔木有21种,该结论也可为环境条件类似地区水土保持乔木树种选择提供参考。For selection of arbor tree species for the purpose of soil and water conservation,an assessment indices system was structured combining site investigation,expert judgment and hierarchy analysis,which gives weights and scores for each index to assess the tree on a integrated basis.The result showed that there are total 599 species from 251 general belonging to 96 families located in Cewu,Zhuotian and Hetian.There are 118 species of high frequency.The capacity grade of soil and water conservation is assessed as grade II meaning"better"among the three grades of assessment.23 tree species are ranked grade I for good capacity in soil and water conservation,74 tree species grade II for better capacity and 21 tree species grade III for moderate capacity.The assessment grade provides a good reference for the work of soil and water conservation in Changting.
