【摘要】 为探讨水库消落带植被重建技术,对广西一些有代表性的水库的消落带植被群落组成、分布以及生态特性等进行了系统调查。调查表明:在水深>15 m的消落带中,未发现有多年生植物;在水深0~15 m的消落带中,多年生的植物主要是草本类,有6科13种,其中有禾本科的硬骨草、扁穗牛鞭草、棒头草及类芦、羊茅等5种,蓼科的头花蓼等3种,苋科的空心莲子草,马鞭草科的过江藤,莎草科的粉被苔草、青绿苔草,以及蕨类的海金沙科的海金沙,其共同特点是耐淹、耐压又相对耐旱。硬骨草、扁穗牛鞭草、类芦及头花蓼各地都有,余则零星分布于各地。更多还原

【Abstract】 It conducts a systematic survey on the composition,distribution and ecologic characteristics of plant community in typical water-level-fluctuation zone of reservoirs in Guangxi for approaching rebuilding techniques of vegetation in fluctuation zone of reservoir.The outcomes show that it has not found perennial plant in fluctuation zone at water depth > 15 m and;the main perennial plant in fluctuation zone at water depth 0-15 m is herbaceous category of 13 species in 6 families,including 5 species of Panicum repens L.,Hemarthria compressa(L.f.)R.Br.,Polipogon sp,Neyraudia reynaudiana(Kunth) Keng,Festuca ovina L.of Gramineae,3 species of Polygonum capitatum Buch.-Ham.ex D.Don of Polygonaceae,Alternanthera philaxeroides(Mart.) Griseb of Amaranthaceae,Phyla nodiflora(L.) Greene of Verbenaceae,Carex pruinosa Boott and Carex leucochlora Bge.of Cyperaceae and Lygodium japonicum(Thunb.) Sw.of Lygodiaceae of pteridophyte.Their common characteristics are water-tolerant,drought-enduring and pressure-resistance.Panicum repens L.,Hemarthria compressa(L.f.)R.Br.,Neyraudia reynaudiana(Kunth) Keng and Polygonum capitatum Buch.-Ham.ex D.Don are everywhere and the others sporadic scattered.更多还原
