| 摘 要： | 城市热岛效应作为现代城市气候的主要特征之一,目前在大部分地区城市有日渐严重的趋势.基于当前城市热岛研究现状,根据城市园林绿化植物生态作用的有关原理,结合长沙市城市中心区与城市郊区两地的气候测量数据,选取城市典型地段的绿地小气候进行实测分析.结果表明:城市园林绿化可从根本上大大改善城市下垫面热力学特性,是有效改善城市热岛效应的重要措施之一;合理的绿化结构和植被类型,能使城市园林绿化充分发挥其综合效益.

| Abstract: | Urban heat island effect,as one of the major characteristics of a modern city,has become an increasingly serious problem in most cities.Based on the current status of heat island effect research and the ecological theory of urban landscape plants,and analyzing the climate data of the suburbs of Changsha and the city proper,this paper selected lots of green urban climate models for measuerment and analysis.The study results show that urban landscape,being one of the important measures to effectively reduce urban heat island effect,can greatly improve urban surface thermodynamic properties.Reasonable green structure and vegetation types can give urban landscape a full play of its comprehensive benefits.This study may increase the intensity of urban landscape garden plants in Changsha and promote the attention to their environmental benefits,offering some reference for the evaluation of the ecological garden city. |
