摘 要:
评价指标体系的建立是观测森林植被的恢复程度首要和关键步骤.在系统分析和整合了现有研究成果的基础上,初步构建了包括物种丰富度、林分蓄积量、物种多样性、显著度、盖度、郁闭度及群落高度7个指标的林型尺度森林植被恢复评价指标体系,采用层次分析法计算出指标权重.并在莲花山国家级自然保护区选取样地进行了实例研究,结果表明：该指标体系能较客观地反映林型尺度的森林植被恢复程度,具有一定的科学性、客观性和可操作性.[著者文摘]

Abstract:
Establishing evaluation indicator system should be the primary and crucial step for evaluating restoration effectiveness of forest vegetation. On the basis of systematic analysis and review of the current researches, an forest restoration evaluation indicator system on scale of forest type had been developed, in which seven indexes were selected including the species richness, stand volume, species diversity, conspicuousness,coverage, degree of closeness and height of forest communities. The index weight value were calculated by the analytic hierarchy process（AHP）. Furthermore, the Natural Forest Protection Pro- ject Area in the Lianhua Mountain National Nature Reserve was taken as the material of corresponding case study based on sample plots. The case application proved that the evaluation indicator system could reflect actual restoration degree of forest vegetation on scale of forest type, and had scientific nature, objectivity and operability in certain extent.[著者文摘]
