摘要: 外来树种是城市绿化的重要组成部分,但外来树种在城市绿地系统建设中有利有弊。在外来树种定义和内涵分析的基础上,从外来树种增加城市绿化树种种类、丰富城市绿地景观多样性、改善城市生态环境角度总结了外来树种在城市绿地系统建设中的作用,并从外来树种可能引发病害、虫害和树种生态入侵等角度探讨了外来树种在城市绿地系统建设中的潜在危害。笔者认为:城市绿地系统中的外来树种规划应从遵循植物引种规律,进行树种入侵生态风险评估,防止外来树种引发的病虫害,先少量、定点引入试种,引种过程中注意隔离保护。根据试种表现确认是否应用等5个方面进行规划,以充分发挥外来树种在城市绿地系统建设中的作用,避免其危害。

Abstract: Alien tree species are the important parts of urban greening, but alien tree species have their own advantages and disadvantages in the urban green space ecosystem construction. Based on the analysis of alien tree species definition and connotation, the functions that alien tree species increase greening tree category, enrich landscape diversity of urban green space and improve urban ecology environment in the urban green space ecosystem construction were summarized. The potential hazards that alien tree species were likely to bring plant diseases and insect pests and tree species ecology invasion into urban green space ecosystem were discussed too. To fully exert alien tree species advantages and avoid their disadvantages in the urban green space ecosystem, in this paper, the five principles of alien tree species planning were pointed out. For example, how to follow plant introduction laws, how to evaluate tree species ecology invasion risk, how to prevent plant diseases and insect pests, how to a little introduce to plant experimentally in fixed field and attentively separate protecting during the introduction, and how to decide about the planting results?
