Community Structure Characteristic and Species Diversity of Zygophyllum xanthoxylum in Minqin
摘要
Abstract
Studying the Zygophyllum xanthoxylum species diversity have great significance for reasonable protection and utilization of Zygophyllum xanthoxylum sources in Minqin.The community structure and diversity characteristics of Zygophyllum xanthoxylum community was researched by using quadrat investigation in different distribution areas in Minqin,the results show that:(1) Zygophyllum xanthoxylum community structure is simple and species is monotonous.There are 39 kinds of species belonging to 12 families and 31 genera.There are more single genus that contribute 50 percent of total genus; (2) Population density of Zygophyllum xanthoxylum is higher in sand gravel field,but growth is smaller.Fixed and semi-fixed sand is opposite.Growth and density of Zygophyllum xanthoxylum was influenced by habitat.(3) Species is rich relatively,species diversity index is higher,community stability is well,community dominance index is lower in sand gravel field,but community composition of fixed and semi-fixed sand is single,structure is simple,species diversity index is lower,ecological dominance is higher,and community stability is poorer.关键词
