    摘要:

    针对我国在海绵城市建设中未能足够重视城市树木对雨水径流削减功能的问题,在简述中美两国关于城市树木和径流削减关系研究的基础上,比较分析了两国城市树木管理方面的法规、专项规划以及规范标准中涉及雨水管理的相关内容,指出我国目前还存在缺乏对城市下垫面及城市树冠的精细化分析、对城市树冠的生态功能及相关指标重视不足、在树种和种植位置的选择上缺乏对雨水径流控制的考量等问题。建议加强基础资料的积累和公开、深化树木削减雨水径流能力的基础研究以及完善相关规划和规范标准。

    Abstract:

    In view of the problem of insufficient attention paid to the reduction function of urban trees on rainwater runoff in the construction of sponge cities in China, on the basis of a brief description of the relationship between urban trees and runoff reduction in China and America, this paper compares and analyses the relevant contents of urban tree management regulations, special planning and standards in China and America concerning rainwater management. It is pointed out that there are still some problems in China, such as lack of detailed analysis of urban underlying surface and urban tree canopy, insufficient attention to the ecological functions and related indicators of urban tree canopy, and lack of consideration of rainwater runoff control in the selection of tree species and planting location. It is suggested that the accumulation and publicity of basic data should be strengthened, the basic research on the ability of trees to reduce rainwater runoff should be deepened, and the relevant planning and normative standards should be improved.
