| 中文摘要: |
| 为提升和发挥塞罕坝森林康养功能,利用2020—2022年塞罕坝及周边共3个空气负氧离子
站监测数据,以及同期对应的气象环境数据,根据隶属度函数及森林康养气象条件综合评价指数等公式,分析空气负氧离子浓度、人体舒适度、空气质量等因子的康养适宜性特征,以及适宜森林康养
的时间。结果表明,塞罕坝及周边森林空气负氧离子浓度值超过2 000 个/cm3,月变化均呈“单峰型”分布,空气负氧离子条件全年均适宜康养;塞罕坝及周边森林仅在夏季舒适度等级为-1~0 级,
舒适度条件适宜康养,其他季节均不适宜康养;塞罕坝及周边森林年、季、月PM2.5、PM10浓度分别
低于35、50 μg/m3,均呈现冬季最高、夏季最低特点,PM2.5、PM10浓度月变化分别呈“W”型分布及
先减后增的变化趋势,全年空气质量条件均非常适宜康养;利用森林康养气象综合评价指数计算得
出,塞罕坝及周边森林康养气象综合评价指数月变化呈“单峰”型分布,峰值出现在7月,6—9月综
合评价指数均超过0.7,为适宜康养月份,南部地区适宜康养的时间长于北部。 |

| To enhance and fully utilize the forest health and wellness function of Saihanba, this study utilized
monitoring data from three air negative oxygen ion stations in Saihanba and its surrounding areas
from 2020 to 2022, along with corresponding meteorological data. By applying membership functions and
a comprehensive evaluation index for forest health and wellness meteorological conditions, the suitability
characteristics of factors such as air negative oxygen ion concentration, human comfort, and air quality
were analyzed, as well as the optimal times for forest health and wellness. The results indicated that the concentration of air negative oxygen ion in the air of Saihanba and its surrounding forests exceeded 2 000
ions/cm3, with a monthly “single-peak” distribution, making the air negative oxygen ion conditions suitable
for health and wellness throughout the year. The comfort level in Saihanba and its surrounding forests
was only at levels -1 to 0 during summer, making it suitable for health and wellness during this season,
while other seasons were less suitable. The annual, seasonal, and monthly PM2.5 and PM10 concentrations
in Saihanba and its surrounding forests were below 35 and 50 μg/m3, respectively, with the highest levels
in winter and the lowest in summer. The monthly variations in PM2.5 and PM10 concentrations showed a
“W” shaped distribution and a trend of decreasing followed by increasing, with air quality conditions being
highly suitable for health and wellness year-round. Using the comprehensive evaluation index for forest
health and wellness meteorology, it was calculated that the monthly variation of the index in Saihanba
and its surrounding areas followed a “single-peak” distribution, peaking in July. The comprehensive evaluation
index exceeded 0.7 from June to September, indicating these months as suitable for health and
wellness, with the southern region having a longer suitable period than the northern region. |
