摘要
通过对重庆市特有植物种类组成、生境及分布、珍稀濒危状况以及特有植物应用潜力的研究,结果显示:①重庆市特有植物为67科146属,共计262种(含种以下单位),其中被子植物为228种,占绝对优势,而裸子植物仅为1种;②重庆特有植物主要分布于渝东北部、东南部及中北部区县的森林、灌丛、荒坡及沟谷等生境地带,以东北部的城口和东南部的南川分布最多;③在分布的海拔上,以分布在海拔1 500 m以下的种类占优势;④重庆市特有植物种类丰富,园林应用潜力大.
The species composition,habitat and distribution and rare and endangered status of the endemic plants of Chongqing were investigated and the potential of their application in landscape architecture was studied.The results showed that 262 endemic species belonging to 67 families and146 genera are distributed in Chongqing,including 228 species of angiosperms and only 1 species of gymnosperm.They are mainly distributed in the forests,shrubs,slopes and valleys of the northeast and southeast parts of Chongqing and its north-central districts/counties,particularly in Chengkou and Nanchuan.Species distributed in regions at an elevation of less than 1500 meters are dominant.It is concluded that Chongqing is abundant in endemic plants,which have a great potential of application in landscape architecture.
