摘要
对黄河兰州段湿地植物区系组成、生态特征和物种多样性进行了系统分析。结果表明:黄河兰州段湿地共有植物132种,隶属于33科90属,菊科、禾本科、藜科、莎草科和蝶形花科是物种数占前5位的科,占总种数的59.85%;蒿属、藜属、蓼属和藨草属是含物种数占前4位的属,优势科、单种属现象明显。湿地植被分为9个群丛,包括木本群丛2个(旱柳群丛、柽柳-枸杞群丛),草本群丛7个(芦苇-萹蓄群丛、莳萝蒿群丛、酸模叶蓼-灰绿藜群丛、垂穗鹅观草-宽叶独荇菜群丛、碱蓬群丛和地肤-冰草群丛);并提出了对黄河兰州段湿地植被保护利用的对策。
Based on investigating the wetland resources of Yellow River in Lanzhou on,analysis the wetland flora composition,species diversity and ecolo 132 plants in wetland plant along the Yellow gic Ri al characteristics systematicly. The results show that： there are ver, belonging to 33 families and 90 genera. Asteraceae, Poaceae, Chenopodiaceae,Cyperaceae and Fabaceae species is the number of families accounted for the top five, share to 59.85% of the total amount,Artemisia,Chenopodium,Polygonum spec and mariqueter is the number of genera accounted for the top four, dominant families, single-species phenomenon obviously, wetland vegetation at Lanzhou section of the Yellow river is divided into 9 associations. Including 2 woody associations, there are Salix matsudana Ass. Tamarix chinensis ＋ L ycium chinense , and 7 herbaceous associations, there are Phrag mites＋ Pol ygonum aviculare Ass. Artemisia anethoides Ass. Pol ygonum la pathifolium ＋ Chenopodium glaucum Ass. Calamagrostis pseudophragmites ＋ PhragmitesAss. Roegneria nustans ＋ Lepidium latifolium Ass. Suaeda glauca Ass. Kochia scoparia ＋Agropyron cristatum. And proposed countermeasures of wetland vegeta- tion protection and utilization of the Yellow River in Lanzhou
