滨水空间开发中生态绿道对大气的净化作用研究

Study on Purification of Atmosphere by Ecological Greenway in Waterfront Space Development

文章分析了滨水空间开发中生态绿道的建设,从树种配置、绿道慢行、绿道服务设施几个方面,分析了滨水空间开发中生态绿道对保证滨水空间不被蚕食、提高滨水空间功能所起到的积极作用。根据绿道建设和功能划分,从滞尘功能和吸收有害气体两方面研究生态绿道对大气净化作用,不同绿地结构起到的减尘效果存在差异。以TSP值为标准,乔灌草减尘能力最优,建议采用复合型植物结构防尘纳污;成年阔叶树能够高效吸纳大气中的有害气体。同时,文章还给出了一些生态绿道防污建议。

The article analyzes the construction of ecological greenways in the development of waterfront space.From the aspects of tree species configuration,slow greenway,and greenway service facilities,it analyzes the importance of ecological greenways in waterfront space development to ensure that the waterfront space is not the positive effect of improving the function of waterfront space.According to the construction of greenways and the division of functions,the effects of ecological greenways on the purification of the atmosphere are studied from the aspects of dust retention and harmful gas absorption.Different green space structures have different dust reduction effects.Based on the TSP value,trees,shrubs and grasses have the best dust reduction ability.It is recommended to use a composite plant structure to prevent dust and pollution;adult broad-leaved trees can efficiently absorb harmful gases in the atmosphere.At the same time,the article also gives some suggestions on ecological greenway pollution prevention.
