城镇环境绿化的若干生态学问题思考

The ecological issues in making town environment green

简述了我国城镇绿地规划功能,从生态学原理阐述了物种生态习性、种群间关系、群落结构、群落演替、边缘效应、生物多样性、生态入侵、转基因生物及抗污染性等城镇环境绿化应遵循的原则,指出以生态学原理进行城镇绿地规划、指导城镇绿地群落设计是实现城镇环境绿化最佳生态效益的前提。

The actual layout of town greenbeh is summarized briefly. In the meantime, the fact that environmental afforestation in towns must follow the ecological principle is discussed from nine aspects,i, e. the ecological characteristics of species, the relationships among the species, community structure, community succession, edge effect, biodiversily, ecological invasion, genetically modified organisms and antipollution. Finally,it is indicated that the precondition of achieving optimal eco-efficiency in town afforestation is to apply the ecological principles in marking out town greenbelt and designing the community of town greenbelt.
