| 摘要: |
| 利用2016年5月-2017年4月赤水市境内复兴驿站、古迹驿站及相邻县市内共6个大气负氧离子自动观测点和气象站的观测资料,分析了赤水市大气负氧离子浓度的时空变化特征及其与气象因子的关系。参照世界卫生组织制定的空气负氧离子等级标准,区划赤水市空气负氧离子的等级。结果表明：(1)日均大气负氧离子浓度5056个/m3,高于临近县市的负氧离子浓度,白天略高于夜间,远远超过负氧离子含量的一级标准；(2)年均大气负氧离子浓度为5125个/m3,各季节浓度相差不大；(3)赤水市大气负氧离子浓度空间分布规律为复兴站>古迹站,景区大于街道；与邻近县市比较,植被覆盖率大的区域大气负氧离子浓度高于植被覆盖率小的区域；(4)不同天气条件下大气负氧离子与气象因子的相关性不同,在雨日,大气负氧离子与气温、气压、水汽压相关；无雨日,大气负氧离子与日照相关；同时,白天雨对于大气负氧离子浓度的增加较夜雨更为明显。 |

| Abstract: |
| Using the observation data of the atmospheric negative oxygen ion from May in 2016 to April in 2017, the 2 observation points of the rejuvenation post station and the historic post station are used.The results showed that:(1) The concentration of negative oxygen ions in the atmosphere is 5056 /m3, which is higher than the concentration of negative oxygen ions in the adjacent counties and cities, and the daytime is slightly higher than that in the night.(2) The annual atmospheric negative oxygen ion concentration is 5125 /m3, and the summer is slightly lower than the other seasons.(3) The distribution law of atmospheric negative oxygen ion concentration in Chishui, the revival station is higher than the antiquities station, scenic area is larger than street.(4) Under different weather conditions ,the relationship between atmospheric negative oxygen ions, such as rain, the air of negative oxygen ions and temperature, pressure and vapor pressure; no rain days, atmospheric oxygen anion and sunshine; at the same time, day and night rain rain on the atmospheric concentration of negative oxygen ions increase has a significant positive correlation. |
