长三角新农村庭院植物多样性与配置模式

选择长三角地区代表性新农村,研究其农户庭院植物多样性和配置,分析庭院植物物种组成、多样性和相似性,按不同庭院类型分析了植物配置模式.结果表明:在被调查的400户庭院中,共栽种134种植物,隶属于68科113属,60户没有栽种任何植物；新建的农民集中居住区物种丰富度不高；不同地区庭院木本植物物种的相似性较高；庭院植物配置...

Diversity and Allocation Pattern of Courtyard Plants in New Countryside in Yangtze River Delta

The purpose of this paper is to study the diversity and allocation pattern of courtyard plants in the representative new countryside in Yangtze River Delta.The composition,diversity and similarity of plant species and the allocation patterns for different courtyard types were analyzed.A total of 134 species of plants,belonging to 113 genera and 68 families,were planted in the 400 courtyards being surveyed,and 60 households didn’t plant anything in their courtyards.In the newly built communities,the plant species is scarce.A big similarity in woody plant species was observed in the courtyards between different areas.The courtyards can be divided into three types,and the courtyard plants can be divided into 16 allocation patterns.It is concluded that some green spaces already exist in the courtyards of the Yangtze River Delta,but the application of the indigenous plants and the diversity of plant species still need to be improved,and the allocation patterns should be enriched.Some suggestions and countermeasures are proposed.
