重庆市景天科植物资源调查及其垂直绿化优势

摘要

采用样带和样方相结合的方法，对重庆市景天科植物资源进行调查。结果表明：重庆市景天科植物有28种，主要分布在开县、城口、江津、巫山和巫溪，分别占重庆市景天科植物总数的96.43％、85.71％、75.00％、75.00％和71.43％，凹叶景天、佛甲草、垂盆草、费菜、珠芽景天、细叶景天和齿叶景天分布比较广泛。耐旱性强、繁殖力强、管理容易、品种繁多、植株矮小和生态效益好是景天科植物在垂直绿化中的应用优势。%Using belt transect method and quadrat sampling method , Crassulaceae plants resources in Chongqing has been investigated .The results showed that there are 28 species of Crassulaceae plants in Chongqing , which mainly distributed in Kaixian , Chengkou , Jiangjin , Wushan and Wuxi , accounted for 96.43%, 85.71%, 75.00%, 75.00%and 71.43%of Crassulaceae plants species number respectively in Chongqing .Sedum emarginatum Migo, Sedum lineare Thunb, Sedum sarmentosum Bunge, Sedum aizoon L., Sedum elatinoides Franch and Sedum odontophyllum Frod distributed widely in Chongqing . The advantages of Crassulaceae plants in vertical greening include high drought tolerance , strong repro-ductive capacity , easy management , many species , dwarf plants and good ecological benefits .
