城市绿地空气负离子浓度评价研究——以杭州西湖风景区为例

Evaluation of Aero-anion Concentration in Urban Greenbelt——A Case at the Scenic Area of West Lake in Hangzhou

采用AIC1000型空气负离子浓度测试仪,对西湖综合保护工程实施范围内的不同绿地进行了空气负离子浓度测定,结果表明,不同绿地空气负离子浓度排序依次为:乔灌草型>疏林草地型>滨水绿地型>硬质铺地型,且滨水绿地型样地与硬质铺地型差异较小。与此同时,西湖风景区的空气负离子浓度显著高于城市中心区。

AIC1000 type detector was used to detect the values of the aem-anion concentration at different greenbehs in the area covered by the comprehensive protection project of West Lake. The results showed various types of space ranking in different aero-anlon concentration as follows ： space with trees, shrubs and grass 〉 space with sparse trees and grass 〉 water fronts and greenbelts 〉 solid pavement, of which there was no significant difference between the water fronts-greenbehs and solid pavement. Meanwhile the concentration of aero-anion in the scenic area of West Lake is significantly higher than that in downtown.
