Plant diversity and systematic composition of dump site in Baiyinhua No.2 M ine
摘要
Abstract
[Objective]Master the current status of vegetation in the ecological restoration of the Baiyinhua No.2 Mine dump,and explore the basic composition,species diversity,and characteristics of seed plant flora in the dump.[Method]The floristic seed plants of the dump were statistically analyzed following the basic principles of floristic ge-ography.This analysis involved consulting data and conducting field investigations.We used a method of measuring biodiversity within a limited sample,through field sampling and sample processing,statistical analysis is conducted on the distribution,life form,and ecological structure of plant families and genera,and the species diversity of plant com-munities is calculated.[Result]The plants in the wetland consisted of 45 families,148 genus and 219 species,with 51.Chenopodiaceae,Leguminosae,Asteraceae,Gramineous,plants predominated in this area.The plant life form is mainly perennial herbaceous plants,and the plant ecotype form is mainly mesophytic;This survey included 43 com-munities.Specie Richness Idex was 3~14,Shannon-Wiener Diversity Index(H)was 0.837~2.541,The Simpson Diversity Index(D)was 0.420~1.212;We observed that families and genus of the plants were different.A total of 28 families spread around the world;10 families belonged to temperate zone;28 genera spread around the world;100 families belonged to temperate zone.[Conclusion]The plant species have increased significantly after natural and arti-ficial restoration,and the plant community has reached a certain degree of stability but is still in the preliminary stage of ecological restoration,currently undergoing positive succession.关键词
