休闲观光果园对环境空气质量影响的研究

Study on the Influence of Leisure Orchard on Environmental Air Quality

以河北省平山县特色休闲果品基地和平山城区为调查地,研究休闲观光果园环境空气质量的变化规律。结果表明：在5~10月生长季,园区比城区平均降温0.5~1.6℃,增温幅度7.5~14.3个百分点。园区负氧离子浓度以早8：00为最高,为2.1×103个/cm3,园区空气颗粒物浓度比城区低57.7%,在8：00~12：00时段降低59.1%~87.4%。园区环境空气质量以上午最佳,推荐适宜游园的时间为8：00~12：00时段。

In Pin Shan County town and Pingshan County fruit base as the research site,Study on the infulence of leisure sightseeing orchard on environmental quality.Results showded that：In growing season from May to October,The park is 0.5~1.6℃ degrees Celsius than the city,Humidification rate 7.5~14.3 percentare point.Park negative oxygen ion concentration in the early 8：00 as the highest,For 2.1×103 个/cm3.The concentration of airborne particulate matter in teh park is 57.7%lower than that in urban area,Reduced 59.1%~87.4% during 8：00-12：00.Park ambient air quality is best in the morning,The recommended time for 8：00~12：00 for the garden.
