摘要
以呼和浩特市树木园内5种植物群落类型所在绿地为研究对象,以硬质广场为对照点,开展空气质量监测,探究城市公园绿地不同植物群落类型的生态环境效应。结果表明:5种植物群落人体舒适度指数(I_(CHB))处于Ⅵ级,空气负离子浓度(C_(NAI))处于一般水平,大气颗粒物浓度(C_(APM))达到国家二级环境空气质量标准,部分植物群落的生态环境效应优于对照点。夏季晴朗无风天气下,推荐游人9:00-10:00或16:00后在树木园内样地S1(杜松-长白松-侧柏)内开展游憩活动。
The eco-environmental effects of different plant community types in urban park green space are investigated by taking the green space where five plant community types are located in the Hohhot Arboretum as the research object and the square as the control point for air quality monitoring.The findings show that the human comfort index of five plant communities in the arboretum is at grade VI,and the concentration of NAI is at general level.The concentration of airborne particulate matter achieves the second level of national ambient air quality standard.It is found that the eco-environmental effects of some plant communities are better than that of the control point.When the weather is sunny and windless in summer,visitors are recommended to carry out recreational activities in plot S1(Juniperus rigida-Pinus syluestriformis-Platycladus orientalis)in the arboretum from 9:00 to 10:00 or after 16:00.
