Residential area' s vegetation will become an important component of China's urban vegetation, and the distribution pattern of its diversity will affect urban vegetation diversity. Based on the residential area's vegetation investigation in the urban, suburban, and rural areas of Shanghai, the plant diversity and species composition in the residential areas along the urban-rural gradient were compared in terms of ornamental plants (OP), spontaneously occurring ornamental plants (SOOP), and weeds. There was no significant difference in the species richness of OP and weeds along the gradient, but the richness of SOOP was the highest in suburban area. The species compositions of OP, SOOP, and weeds were similar in the residential areas along the gradient, with 40-50% of all species occurring in more than one location. The main causes inducing the homogenization of plant diversity in Shanghai residential areas were the almost identical residential building styles and greening patterns, which limited the planting of greening plants and the construction of heterogeneous habitats.
居民区植被将成为中国城市植被的重要组成部分，其多样性分布格局会影响城市植被多样性。基于对上海市区、郊区和农村地区居民区植被的调查，从观赏植物（OP）、自然发生的观赏植物（SOOP）和杂草方面，比较了城乡梯度上居民区的植物多样性和物种组成。沿梯度方向，OP和杂草的物种丰富度无显著差异，但SOOP的丰富度在郊区最高。沿梯度方向的居民区中，OP、SOOP和杂草的物种组成相似，所有物种中有40%-50%出现在不止一个地点。导致上海居民区植物多样性同质化的主要原因是几乎相同的住宅建筑风格和绿化模式，这限制了绿化植物的种植和异质生境的构建。
