| 摘 要： | 在对福建省长汀县崩岗侵蚀区全面调查的基础上,选择4种生物治理模式,分别从植物的种类、数量、盖度及生长状况等方面进行群落调查,同时对乔灌层、草本层植物种类、重要值、生物多样性指数进行不同治理模式下植被恢复效果的评价.结果表明:不同生物治理模式下植被恢复效果不同,经济林+封育模式>乔灌草混交模式>灌草模式>灌木模式>对照,其中经济林+封育模式和乔灌草混交模式的物种丰富度、多样性指数高,植被均匀度高,植被恢复效果好,是崩岗侵蚀区较为理想的生物治理模式.芒萁为崩岗侵蚀区先锋植物,在崩岗侵蚀区的植被恢复中占有重要地位.

| Abstract: | On the basis of comprehensive survey to the collapsing gully erosion at Changting County,four governance models in collapsing gully erosion area were selected to investigate the vegetation species,amount and growth,and the vegetation restoration effects of plant species of tree layer,shrub layer and herb layer,importance value,Simpson index,Shannon-Wiener index and Pielou index were assessed under different governance models.The result showed that vegetation restoration effects were different among four governance models,the model of enclosure after planting economic forest>the model of mixed trees,shrubs and herbs>the model of mixed shrubs and herbs>the model of planting shrubs>CK.The model of enclosure after planting economic forest and the model of mixed trees,shrubs and herbs were optimum,in which plant species richness,biodiversity index and evenness index were higher with good vegetation restoration effect.Dicranopteris dichotoma was a pioneer plant in collapsing gully erosion area,which played an important role in vegetation restoration. |
