摘　　要：为探究福州市周边乡村大气颗粒物浓度的变化特征,以孔元村、井下村为研究对象,选择五一游客高峰期,分别在两村内选取隶属5种游憩地类型的12个监测点,采集颗粒物(TSP、PM10、PM2.5、PM1.0)浓度、气象因子等信息并进行数据整理分析。就村内不同粒径颗粒物浓度的日变化规律、不同游憩地颗粒物浓度特征进行了总结,对气象因素与颗粒物浓度变化的相关性进行研究,对造成这些结果的原因进行推测和讨论。结果表明:1)初夏孔元村、井下村大气中小粒径颗粒物浓度符合国家空气质量一级标准,大粒径颗粒物浓度达到国家二级标准,其中TSP和PM10一日内浓度曲线变化呈现出近似的“N”或“V”字型,PM2.5和PM1.0浓度变化表现出早晨至中午低,傍晚急速升高的斜“V”字形;2)根据游憩地类型划分,大气颗粒物浓度由高至低分别为庙内、硬质铺装游憩地、游憩林地、田园和临水游憩地;3)大气颗粒物浓度与海拔、温度气象要素呈反比,与气压、湿度因素呈正比,且影响作用较大;4)乡村大粒径颗粒物(TSP和PM10)受村民、游人活动影响较大,其扬尘作用尤为突出。To explore the characteristics of atmospheric particulate concentrations at surrounding countryside in Fuzhou City,taking Kongyuan and Jingxia Villages as the research objects,the study selected the peak period for tourists to visit in May 1st,collected and analyzed the atmospheric particulates (TSP,PM10,PM2.5 and PM1.0) concentration,and meteorological factors at 12 monitoring points in 5 kinds of recreational sites.The contents of the study included summary diurnal variation of atmospheric particulate concentration in different particle sizes and the characteristic of particle concentration in different recreational areas,studying on the correlation between meteorological factors and changes in particulate matter concentration,and speculating and discussing the reasons for these results .The results showed that: 1) In the early summer,the monitoring data of Kongyuan and Jingxia villages,small-size concentration reach the national air quality standards-I,and the large-size concentration reached the standards-II.The change in concentration curve of TSP and PM10 in one day shows an approximate "N" or "V" shape,while that of PM2.5 and PM1.0 remained low from morning till noon and grow rapidly at night,as oblique "V".2) According to the 5 types of recreational sites,the region were ordered from high to low by the concentration of atmospheric particulates as follows: the temple,hard paved recreation area,recreational forest,fields and waterfront recreation,;3) The concentration of atmospheric particulate matter is inversely proportional to the altitude and temperature factors,while is proportional to the pressure and humidity factors,and the effect is significant;4) The large-size particles (TSP and PM10) in rural areas were closely related to of villagers’ and tourists’ activities,especially Dust Raising.
