应对气候变化——城市森林树种选择思考

To the Climate Change: Thinks on Urban Tree Species Selection

当今我们依然缺乏气候变化对城市树木影响的知识,很少将气候变暖的科学预测和城市森林研究相结合,对城市森林树种的科学认识不足。作者提出需理性地理解树种规划和树种选择的关系、乡土树种和外来树种的关系、树种丰富度和均匀度的关系、行道树单一性栽植和多树种栽植的关系、树木生长动态和立地的关系、树木生长和气候变化的关系、树种选择和群落配植的关系,需要通过科学研究提出一个具有前瞻性的城市树种名单,建立更合理的树种选择模式来应对城市环境和未来的环境变化。

Today,we have less knowledge on the impacts of climate warming on urban trees,and less thinking on climate change when we make selection of urban tree species. Meanwhile we have done a few researches that combined the forecast of climate worming and urban forest construction,and only less scientific understanding on the most of urban tree species,thus need to provide a prospective list of urban tree species based on future studies. In author’s point of view,we need understanding logistically on the following points： urban tree species planning and selection,native species and exotic species,tree species richness and evenness,monoculture and polyculture for street trees,tree growing and climate worming,tree species selection an plant community design,the dynamic of tree growing and site. Authors provide a rational model for urban tree selection.
