摘要
为更好地将自然公园中的乡土野生草本植物应用于墙体绿化中,采用野外线路调查及资料查阅法,对湖南32个自然公园草本植物区系研究表明:区域内有草本种子植物108个科,698个属,2016种,其地理成分复杂多样,热带性质较为明显。从科、属的组成分析与区系统计来看,科级水平划分为8个分布型,其中世界广布型最多,共44科,其次为泛热带分布型和北温带分布型;属级水平划分为15个分布型及18个变型,以泛热带型分布最多,其次是世界分布属。特有性在科级并无分布,但在属级有中国特有属31个,占中国属数的12.06%,成为区域内最富有特色而又极为重要的成分之一。提出了墙体绿化草本植物选择的三原则,并挑选出湖南可应用于室内和室外墙体绿化的草本植物。
The present work aims to apply native herbaceous plants that occurred in the natural parks to vertical greening by conducting literature review and field surveys.To that end,the herbaceous flora of 32 natural parks in Hunan province was examined.Our result shows that there are a total of 108 families,698 genera,and 2016 species of herbaceous plants in this region.The geographical composition is complex,diverse and towards a tropical nature.Based on the analysis of the composition and regional system of the family and genus,the family level is divided into 8 distribution types,of which the world distribution is prominent,with a total of 44 families,followed by the pan-tropical distribution and northern temperate distribution.The genus level is divided into 15 distribution types and 18 variations,with the dominance from the pan-tropical distribution,followed by the world distribution genus.There is no endemic plant distributed at the family level,but there are 31 genera endemics to China at the genus level,accounting for 12.06%of the Chinese genus,and becoming one of the most distinctive and extremely important components in the region.Based on our results,three principles for the selection of herbaceous plants for vertical greening in the Hunan region were proposed,and the herbaceous plants suitable for indoor and outdoor vertical greening were also selected.
