摘要
城市化和工业化进程的加速,造成了较严重的城市空气污染问题,许多城市都出现了浊岛效应。文中通过文献内容分析法和关注度图谱分析,梳理空气污染物的清除主要取决风速影响污染物扩散稀释速度和风向决定污染物的输送方向,阐释了风环境调节浊岛效应的机制,归纳总结了滨水景观格局中绿地植被、水体、人工建筑及其各元素组合效应与风环境关系的研究进展,建构了滨水景观格局风环境与城市浊岛效应的关联。通过城市自身的合理空间配置来缓解城市空气污染问题,是保障城市空气环境非常有效的途径之一。因此,加强城市滨水景观格局风环境的研究对于改善城市空气污染具有重要意义。
With the accelerated development of urbanization and industrialization,urban air pollution becomes more serious and turbid island effect comes into existence in many cities.Firstly,the present article sums up two factors,wind speed and wind direction,in removing air pollutant with the methods of literature review and diagram analysis.Wind speed can influence the spread of air pollutant and the dilution effect of wind speed,while wind direction may determine the direction of the air pollutant drift.Secondly,we explain the mechanism of the condition and regulation of wind environment on the urban turbid island.Thirdly,we tease out the research progress in the relationship between wind environment and the factors of waterfront landscape pattern,like green vegetation,water,artificial building,and the combined effects of them.And finally,we establish a co-relation between waterfront landscape pattern and urban turbid island effect,and we believe that reasonable spatial arrangement of cities can solve the problem of urban air pollution to some extent and forms one of the efficient protections of urban air environment.It is significant to strengthen the research on urban wind environment of waterfront landscape for the purpose to reduce urban air pollution.
