摘　　要：南方集体林区常绿阔叶林的健康评价问题已受到各界关注,文中主要是研究基于不同赋权法的常绿阔叶林健康评价问题。首先对常绿阔叶林健康评价指标采用层次分析法、熵权法和组合赋权法3种方法分别进行赋权,然后分别对福建省将乐林场国有林场(以下简称将乐林场)1996年和2007年的常绿阔叶林小班进行健康评价。通过分析比较确定组合赋权法为最佳赋权法,以此得到将乐林场常绿阔叶林在1996年健康指数均值为0.60,处于亚健康水平,在2007年健康指数均值为0.62,处于健康水平,健康水平有所改善,符合实际情况,本研究结果为常绿阔叶林健康评价提供了方法依据。As the evergreen broadleaved forest health evaluation being increasingly concerned in southern collective forest, health assessment of evergreen broadleaved forest by different weighting method was dealt with. The health evaluation indices of evergreen broadleaved forest were weighted by analytic hierarchy process, entropy method and combination weighting method, respectively, followed by the health evaluation for the sub-compartments of evergreen broadleaved forest in 1996 and 2007, respectively in Jiangle State-owned Forest Farm, Fujian Province. Thus the combination weighting method was regarded as the most ideal by comparison. Meanwhile, the mean value of health indices of the evergreen broadleaved forest was discovered to be 0.60 at subheahh level in 1996 and 0.62 at health level in 2007, so as to offer an approach to health assessment for evergreen broadleaved forest .
