选择常熟地区代表性乡村,对农户庭院植物多样性和配置模式进行研究,分析其植物物种组成和多样性,并利用TWINSPAN分类方法,研究了庭院植物配置类型与模式.结果表明:在对281个户级庭院调查中,170户庭院中栽种植物,111户庭院中无任何绿化,共栽种植物151种(含变种、栽培品种),隶属58科116属;庭院植物配置可划分为4种庭院类型和10种配置模式;植物的层次结构对于多样性指数影响较大,植物配置模式的结构越丰富、复杂,其物种多样性指数越高.认为观赏性植物成为庭院的主体植物,观赏功能成为庭院植物的主要功能;庭院内有效绿化面积不足,单位面积植物生态效益较低;乡土植物景观建设与物种多样性保护有待于进一步加强.

The construction of ecological plant landscape in rural areas is an important part of the program of building of a new socialist countryside. A village typical of the Changshu region was chosen for analysis of species composition and diversity of household courtyards and for investigation of their plant diversity and models of configuration with the TWINSPAN classification method. It was found that out of 281 household courtyards, 170 had plants and 111 did not have any. The plants growing in the courtyards included a total of 151 plant species, belonging to 116 genera and 58 families, which formed 4 types of courtyards and 10 models of configuration. The species diversity index demonstrated a significant relationship with steoro structure of the plants, showing the richer and the more complex the latter, the higher the former. It can, hence, be concluded that ornamental plants dominate the courtyards and play a major role of ornamentation;courtyards fail to keep an effective greenland area adequate to maintain a proper per-unit-area plant ecological benefit;and the construction of native plant landscape and species diversity needs to be further improved.
