摘    要:对上海市郊外环林带两侧总悬浮颗粒物浓度(简称TSP)和可吸入颗粒物浓度(简称PM10)同步测定表明:林带的防尘效应与风向有关,下风向处的TSP与PM10日均浓度均分别比上风向低19%-44%和39%-61%。林带边粒径分布测定结果表明:下风向处较大粒径颗粒物的相对含量比上风向处小一些;冬季的粒子谱分布呈现较大粒子和较小粒子重量累积百分比较高、中等粒子的重量累积百分比较低的态势;而春季则相反,中等粒子的重量累积百分比较高、较大粒子和较小粒子则比较低。说明冬春不同风向条件下上海市郊的大道旁林带区具有一定的防尘效应。

Abstract:The concentration of total suspended particulates(TSP) and airborne particulate matters(PM10) in both sides of looped forests in Shanghai outskirts in winter and spring seasons were synchronously measured.The results showed that the dustproof effect of forests was related with the wind direction.The daily mean concentration of TSP and PM10 in the forest-leeward was 19%~44% and 39%~61% lower respectively than that in the forest-windward.The results of measurements for the particulates radius distribution showed that the relative content of the bigger granule matters in the forest-leeward was smaller than that in the forest-windward.The accumulated weight percentage of the bigger and the smaller particles was high in winter,while the accumulated weight percentage of the middle particles was low in winter.However,in the spring,the accumulated weight percentage of the middle was high and the accumulated weight percentage of the bigger and smaller particles was low.The results indicated that the roadside forest in Shanghai existed a definite dustproof effect under different wind directions in winter and spring seasons.
Keywords:Shanghai outskirt  Forest  Dustproof effect
