摘　　要：在海口城市植被调查的基础上,对比各类土地利用中的群落组成差异和植物多样性指数,结果显示:1)各个土地利用类型的植物群落组成存在明显差异;2)居住用地、公共管理&商业&工厂用地和公共绿地的植物物种多样性和功能多样性都普遍高于其他类型的土地利用,交通用地的植物物种多样性水平较低;3)空闲地的乔木层与居住用地、公共管理&商业&工厂用地,以及公共绿地的物种丰富度呈现显著差异的情况下,功能丰富度无显著差异。在进行城市绿地空间建设时,规划者们应该在考虑土地开发模式和强度时,制定保护和提升多层次植物多样性格局的策略,以确保城市生态系统的稳定可持续性。On the basis of the urban vegetation investigation in Haikou City,the community composition differences and plant diversity indices in each land use are compared.The results show that:1)there are significant differences in the plant community composition of each land use type;2)The plant species diversity and functional diversity of residential land,public management&commercial&factory land and public green spaces are generally higher than those of other types of land use,and the transportation areas have the lowest level of plant diversity;and 3)There is a significant difference in species richness between residential areas,public management&commercial&factory land,and public green spaces,but there is no significantly difference in functional diversity.When constructing urban green spaces,planners should develop strategies to protect and enhance multi-level plant diversity patterns with the consideration on land development patterns and intensity,so as to ensure the stability and sustainability of urban ecosystems.
