| 摘 要： | 以46个典型样地调查资料为依据,选择与喀斯特植被恢复紧密相关的7个因子构成评价指标,用层次分析法计算各指标的权重值,对植被自然恢复程度进行评价。结果表明:(1)7个因子中群落高度和生物量对植被恢复的影响最大;(2)随着植被恢复由低级阶段向高级阶段发展,恢复程度逐渐增大,至顶极乔林阶段恢复到模式群落的94.12%,这说明群落的结构和功能基本得到了恢复。

| Abstract: | In this paper,46 typical plots were surveyed.Seven factors composed of evaluation index were closely related to karst vegetation restoration.The value of weights of the indexes calculated by the analytic hierarchy process(AHP)to evaluate natural restoration degree of vegetation.The main results showed(1)the community height and biomass effected vegetation restoration most in seven factors;(2)with the development of restoration of vegetation from low-level stage to advanced stage,the restoration degree incre... |
