商洛各景区负氧离子浓度分布与相关性分析

Concentration Distribution and Correlation Analysis of Negative Oxygen Ions in Shangluo Scenic Spots

摘要: 陕西商洛享有“中国气候康养之都”的美称，对当地的相关气候因子开展持续深入研究具有重要的经济意义和社会效应。空气中负氧离子浓度的高低是衡量空气质量好坏的重要指标。本文对商洛市11个主要景区的负氧离子监测数据进行统计分析，结果表明当地负氧离子浓度呈现一定的年变化特征，夏、秋季高，冬、春季低；每年4~8月和11月下午负氧离子浓度高于上午，其它月份均为上午略高于下午；负氧离子浓度变化与温度、湿度、风速有关，而与气压、二氧化碳等要素的相关性不太明显。

Abstract: Shangluo, a city in Shaanxi Province, enjoys the laudatory name of “Climate Health Capital of China”, and it is of great economic significance and social effect to carry out continuous and indepth research on local climate factors. The concentration of negative oxygen ions in the air is an important index to measure the quality of air. In this paper, the negative oxygen ion monitoring data of 11 main scenic spots in Shangluo city are analyzed statistically, and the results showed that the local negative oxygen ion concentration showed obvious annual variation, with a high concentration in summer and autumn and a low concentration in winter and spring; the concentration of negative oxygen ion in the afternoon is higher than that in the morning from April to August and November, and it is slightly higher than that in the afternoon in other months; the change of negative oxygen ion concentration is related to temperature, humidity, and wind speed, while the correlation with atmospheric carbon dioxide is not obvious.
