城市化对城市植物多样性的影响主要表现为城市植物同质化趋势明显,城市植物多样性保护面临外来物种的入侵和乡土物种的消失等。城市植物多样性分布呈现乡土物种多样性随城市化程度加深而减小,中心城区乡土物种比重偏少,广场及公共建筑和居民小区的乡土物种比重低而郊区及城市废弃地的乡土物种比重高,城市植物配置缺乏地域特色。而对城市植物多样性研究和保护的现状,需要加强基础研究和数据积累,注重多学科融合与新技术运用,并同时加强环境教育和公众参与。
The impact of urbanization on urban plant diversity is mainly manifested in obvious urban plant homogenization trend, urban plant diversity protection facing the invasion of alien species and disappearance of native species. The diversity of urban plants shows that the diversity of native species decreases with the deepening of urbanization, the proportion of native species in central urban areas is relatively low, the proportion of native species in square and public buildings and residential communities is low, and the proportion of native species in suburban and urban wasteland is high The city plant configuration lack of regional characteristics. The status quo of urban plant diversity research and conservation needs to be strengthened with basic research and data accumulation, with emphasis on multidisciplinary integration and use of new technologies, while enhancing environmental education and public participation.
