Studies on species composition,structure andphysiognomy of shrub communities inTiantong region,Zhejiang Province

According to the data of field plots, this paper deals with preliminary characteristics of shrub communities in Tiantong region, Zhejiang province. The result shows that there are 94 species of vascular plants belonging to 45 families and 76 genera in the shrub communities. The analysis of geographical elements demonstrates that the shrub vegetation is secondary and degraded. The physiognomy of the shrub is mainly decided by the phanerophytes with microphylls, mesophylls, herbaceous, deciduous and evergreen leathery, simple and unentire leaves through analysis of both life form of the plants and their leaf characteristics. Based on the characteristics of the shrub communities, their ecological restoration is also discussed.
