【摘要】 以运城盐湖无机盐工业废弃地改造试验段为调查对象,采用样方分析法,对景观带、淡水湿地带、工业废弃地过渡带和恢复带生物多样性进行调查。结果表明:样地内共有植物74种,分属37个科。物种多样性以淡水湿地带>景观带>过渡带>恢复带;由物种丰富度Margalef和多样性指数Simpson分析,两者趋于一致,淡水湿地带指数最高,景观带略低于淡水湿地带,恢复带指数最低,景观带和淡水湿地带植物种类丰富,且以人工栽培品种占优势,人工干预的效果明显,恢复带和过渡带以草本植物为主,种类单一。更多还原

【Abstract】 Using experimental field in industrial wasteland of Yuncheng Salt Lake as an example, quadrat analysis is conducted on the biodiversity in transition and restoration zones of landscape field,freshwater wetland zone,transitional zone of industrial wasteland,and restoration zone. Results show that there are 74 species of plants belonging to 37 families in the selected land. Diversity of the species is ranked in this order: freshwater wetland zone > landscape zone > transition zone >restoration zone. Analyzed by biological richness Margalef and Simpson Diversity Index,both of them tend to be consistent that index of freshwater wet zone being the highest,index of the landscape is slightly lower than that of freshwater wet zone,and with the lowest index in restoration zone. Both landscape zone and freshwater wetland have rich plant species,and the artificial cultivars were dominant with obvious effect of artificial intervention. The restoration zone and transition zone are dominated by herbaceous plants of single species.更多还原
