【摘要】 通过对研究区空气负离子浓度时空变化特征的研究,为游人在湿地公园中选择游憩地点和游憩时间提供新的参考。对"两湖"公园,即星月湖公园和月亮湖公园的空气负离子浓度进行观测研究,并使用安培系数与空气洁净度对结果进行分析评价。结果显示,夏季空气负离子浓度最高,春秋季次之,冬季最低。空气负离子浓度在14:00—16:00时间段内最低,总体上上午空气负离子浓度高于下午。植物群落组成的CI值:乔灌草>常绿乔草>落叶乔草>灌草>草丛。动态水环境空气洁净度大于静态水环境,其中水面面积大的环境CI值高于水面面积小的。游人选择8:00—10:00和16:00—18:00进入湿地公园进行休闲娱乐活动为最佳,适当调整植物配置方式和增加人工水景能有效提高空气负离子浓度,能为游人提供有效的健康游憩环境。更多还原

【Abstract】 Through the study of the spatial and temporal variation characteristics of the concentration of negative ions in the air in the study area,a new reference is provided for tourists to choose the recreation place and recreation time in the wetland park.The concentration of negative ions in the air in Xingyue lake park and Moon lake park in"Two lakes"park was observed and studied,and the Abe coefficient and air cleanliness were used to analyze and evaluate the results.The results show that the concentration of negative ions was highest in summer,followed by spring and autumn,and lowest in winter.The air anion concentration was the lowest in the period from 14:00 to 16:00,and the overall air anion concentration in the morning was higher than that in the afternoon.CI value of plant community composition:Trees,shrubs and herbs>Evergreen trees and herbs>Deciduous trees and herbs>Shrubs and herbs>Grass.The air cleanliness of dynamic water environment is higher than that of static water environment,and the environmental CI value of large water surface area is higher than that of small water surface area.It is the best choice for visitors to enter the wetland park for leisure and entertainment from 8:00 a.m.to 10:00 a.m.and 16:00 to 18:00 to properly adjust the plant configuration and add artificial waterscape can effectively improve the concentration of negative ions in the air and provide an effective and healthy recreation environment for visitors.更多还原
