摘　　要：为了阐明目前马尾松人工林林分的活力与健康状况,为人工林的经营提供初步分析和建议,以及对今后人工林的经营效果评价提供参考,采用复合结构功能指标法,选用马尾松种群活力、植被群落生态健康和林分抵抗活力3个功能结构层综合指标来构建马尾松人工林林分活力与健康评价指标体系。以衡山马尾松人工林不同年龄发育阶段的小班样地为评价单位,对5个不同年龄发育阶段的15个马尾松人工林小班样地进行马尾松人工林林分活力与健康评价。结果表明:15个小班样地的马尾松人工林总体林分活力与健康状况均处于亚健康状态;林龄为5年、10年和15年的马尾松人工林小班样地内马尾松种群活力H值明显高于林龄为2年和25年的小班样地;各小班样地内植被群落生态状况差别较大,植被群落生态状况为健康的小班主要集中在林龄为2年和25年的小班样地内;各小班的林分抵抗活力状况无太大差异,均处于亚健康状态,与马尾松人工林总体林分活力与健康状况相一致。In order to expound the stand＇ s vitality and health status of Pinus massoninana plantations at present, then, offer some elementary analysis and suggestions for the operators, and reference for the assessments of forestry, the author used the method of functional key performance indication of composite structure, to build the stand＇ s vitality and healthy assessment indicator system of Pinus massoninana plantations, structured by 3 criteria- population vitality of Pinus massoninana, ecological health of vegetation type, and resistance vitality of stand. The diverse phases of cultivation of Pinus massoninana plantations in Hengshan Mountain was taken as sub-compartment samples to evaluate, 15 of which, with 5 distinct growing stages, were put in stand vitality and health assessments. The total stand＇ s vitality and healthy conditions of masson pine plantations were in a sub-healthy state, including 15 sub-compartment samples. Moreover, it was apparent that the H-value of population vitality of 5, 10, and 15 years were much more higher than those of 2 and 25 years. Besides, principally focused on the sub-compartment samples aging 2 and 25 years were in healthy state, the ecological conditions of vegetation type were dissimilar in each sub-compartment samples. However, there was little distinction in resistance vitality conditions between sub-compartment samples, and all of them were in a sub-healthy state. consistent in the total plantation.
