【摘要】 通过对乌裕尔河受损湿地人工播种沙打旺、披碱草和谷稗草进行湿地植被恢复试验,结果表明:物种优势度Simpson指数为0.12～0.47,物种均匀度Pielon指数为0.62～0.91,Margalef指数为3.52～4.79,物种多样性Shannon-Wiener指数为1.51～3.85。谷稗草在恢复试验中形成单一优势种,均匀度较小;沙打旺在试验中优势不明显,丰富度大,均匀度高;披碱草试验中占植物群落结构主导地位,形成优势种,伴生有30%陆生旱生植物。更多还原

【Abstract】 Restoration of wetland vegetation is an important part of wetland ecosystem restoration.The restoration experiments for wetland vegetation was conducted on artificially-sowed Astragalus adsurgens,Elymus dahuricus&Echinochloa crusgalli in the damaged wetland of Wuyuer River.Result shows that the species dominance Simpson index is 0.12-0.47,and the species uniformity Pielon index is 0.62-0.91.The Margalef index is 3.52-4.79,and the Shannon-Wiener index of the species diversity is 1.51-3.85.In the recovery test,the Echinochloa crusgalli formed a single dominant species with less uniformity;the dominant species in Astragalus adsurgens is not obvious in the experiment,the richness is large,and the uniformity is high;the herbaceous plant dominated the plant community structure and formed an advantage.associated with 30%terrestrial xerophyte.更多还原
