Study on Plant Community Characteristics and Species Diversity of Riparian Zone along North Branch of Taizi River
摘要
Abstract
The species diversity is an important trait of plant ecological adaptive strategy. The plant community of riparian zone along north branch of Taizi River plays an important role in stabilizing plant composite. How-ever, the species diversity of riparian zone along north branch of Taizi River is poorly known. Our objectives are to investigate the species diversity of the understory of riparian zone along north branch of Taizi River to provide theory of ecological restoration and technical basis. The diversity of plant species in 18 plots in this ar-ea was investigated by calculating the indices of species diversity, richness, evenness and dominance from im-portant values. The results indicated that: There are 91 species of plants belonging to 18 families and 60 gene-ra in the 18 plots of riparian zone along north branch of Taizi River. The main families are dominant in the Compositae, Gramineae, Cyperaceae, Rosaceae, Polygonaceae; the compositions of the community are con-centrated ,and Zoysia sinica Hance、Sorbaria ( Ser. ) A. Br. 、Artemisia selengensis Turcz. Ex Bess. , Bidens biternata ( Lour. ) Merr et Scheff, Artemisia dracunculus L. , Setaria viridis ( L. ) Beauv. , Carex humida Y. L. Chang et Y. L. Yang, Polygonum hydropiper L. et al. The community structure of riparian zone along north branch of Taizi River is simple in studied area. The ecosystem is deteriorating, with richness indexes change between 4. 00 ~ 17. 00 , Pielou indexes change between 0. 66 ~ 0. 86 ,Simpson indexes change between 0.61 -0.85, Shannon-wiener indexes change between 1. 12 ~2.24, Simpson dominance indexes change be-tween 0. 15 ~0. 39. The riparian zone along north branch of Taizi River are disturbance by human activities, such as agricultural production, dredging and other human activities on reducing the level of community diver-sity.关键词
