摘要/Abstract

摘要： 为探索生态旅游城市张家界市大气 PM2.5、 NO2 浓度与旅游活动及天气因素间的相关性, 运用多重分形去除趋势波动交叉分析法 (MFDCCA) 进行分析。首先验证了张家界市大气 PM2.5、 NO2 浓度与旅游活动及天气因素间的交叉相关性和多重分形特征。然后通过对旅游淡旺季大气 PM2.5、 NO2 浓度与旅游人数、平均气温及相对湿度的多重分形特征的详细分析, 发现在旅游淡季, 大气 PM2.5和NO2 浓度在相对湿度影响下波动范围更大, 且更倾向于出现较低浓度值; 而在旅游旺季, 大气 PM2.5 和 NO2 浓度在旅游活动影响下波动范围更大, 且更倾向于出现高浓度值。

Abstract: To explore the correlation between the concentrations of PM2.5, NO2 in atmosphere and tourism activities as well as weather factors in Zhangjiajie, China, an ecotourism city, the method of multifractal detrended crosscorrelation analysis (MFDCCA) was used. Firstly, the cross-correlation test was carried out and the results indicate that cross-correlation behaviors exist statistically between them.Then the multifractal characteristics between PM2.5, NO2 and number of tourists, average temperature and relative humidity in both low and high tourism seasons were compared. It is found that in the off-season of tourism, PM2.5 and NO2 concentration of Zhangjiajie is affected by relative humidity in a wide range of fluctuations, and is more likely to have lower concentrations. While in the peak tourism season, PM2.5 and NO2 concentration of Zhangjiajie fluctuates widely under the influence of tourism activities, and tends to appear high concentration values.

Key words: multifractal, method of multifractal detrended cross-correlation, PM2.5, NO2, Zhangjiajie
