摘要:
2016 年7 月,选取黑龙江省森林植物园内4 种不同结构绿地计6 个样地,采用TSIAM510 粉尘仪观测PM1.0, PM2.5 质量浓度变化,并使用KESTREL4500 小型气象站实时记录森林植物园内主要气象因子变化,分析不同结构 绿地2 种细颗粒物变化规律以及其与气象因子的关系。结果表明,8:00-18:00,各样地中2 种细颗粒物质量浓度 变化规律为上午高,下午低,高峰值集中在8:00-10:00,低谷值出现在14:00-16:00;植物群落对2 种细颗粒物 均具有削减作用,不同绿地中2 种细颗粒物浓度均值大小为:乔-灌-草绿地>乔-草绿地>草地>灌-草绿地;在乔- 草结构绿地中,以落叶松Larix gmelinii 为主的针叶林削减2 种细颗粒物的能力强于以白桦Betula platyphylla 为主 的阔叶林;2 种细颗粒物质量浓度与温度、风速呈负相关,与相对湿度、大气压呈正相关。
Abstract:
This research investigated two kinds of fine particles(PM1.0, PM2.5)in the atmosphere and meteorological factors (air temperature,relative humidity, wind speed, light intensity and atmospheric pressure)by using the SIDEPAKAM510 and the handheld weather instrument named Kestrel 4500 at Heilongjiang Forest Botanical Garden. The typical weather was chosen to analyze the relationship between the fine particles mass concentration and main meteorological factors in four different structures of green space. The results indicated that: In the 8:00-18:00 observation period, the concentration of two kinds of fine particles in the green land was high in the morning and low in the afternoon. High peak concentration in 8:00-10:00, trough value appears in 14:00-16:00. The different structure of green space has obvious effect on the reduction of fine particles, the mean concentration of fine particles in each community structure is: arbor- shrub -grass compound land > arbor-grass land > grassland > shrub -grassland. the ability of reducing fine particulate matter in the coniferous forest dominated by Larix gmelinii was stronger than that in the broad-leaved forest dominated by Betula platyphylla. Among the meteorological factors, there was a negative correlation between temperature and wind velocity and the concentration of fine particles in the air. The relative humidity and atmospheric pressure were positively correlated with the concentration of fine particles in the atmosphere.
