| Abstract: | On the basis of field investigation data in 2011,the vegetation composition and floristic distribution of Dahuofang Reservoir Protection Zone in Liaoning is preliminarily analyzed,with the aim to master the status of vegetation composition there and provide support for vegetation restoration in a scientific and reasonable mode.The results show that 228 plants are found there,belonging to 66 families and 168 genera.78.51％ of the species belong to herb plants.Monotypic families and families with less than 10 species are comparatively rich,totally accounting for 93.94％ of the whole families.Monotypic genera account for 57.89％ of the whole genera.With regard to the floristic composition in family levels,the main distribution components are in north temperate and pantropical zones. |
