Analysis of spatial and temporal distribution and influencing factors of fine particles in Heilongjiang Province

Based on fine particulate matter (PM2.5) data obtained from the Ministry of Environmental Protection of China, this study focused on analyzing the pollution situation, trends, and pollution frequency changes in the urban area of Heilongjiang Province from February 2015 to April 2019. We also used and analyzed the social emission source list and human comfort index data to examine the potential relationship between the above factors and changes in air quality. And we used the Spearman correlation coefficient to explore the correlation between groups of variables. This study quantified the impacts of social development factors and meteorological parameters on PM2.5 and the INDEX which is a comprehensive consideration of the evaluation indicators (social economy, PM2.5, living environment comfort) through the entropy method and stepwise regression analysis. The key findings included the following: (1) The pollution period in Heilongjiang Province was from October to February, and Harbin had the longest annual pollution period. (2) The PM2.5 concentration was weakly correlated (+) with the energy consumption of industry enterprise (ECIE) and temperature (T). (3) The most significant contributors to INDEX was number of automobiles per 100 Urban Households, which reflected that AUH can be controlled to achieve the goal of reducing PM2.5 concentration on the premise of ensuring stable social and economic development and reducing air pollutants to human health. This showed that social activities played an important role in the economy, air quality, and living environment comfort. This study is of great significance to urban environmental governance.

Analysis of Eco-Tourism Climate Resources in Xingwen, China Based on the Comfort Index and the Negative Air (Oxygen) Ion

The present work investigates an analysis of Eco-Tourism Climate Resources in Xingwen, China based on the Comfort Index and Negative Air (Oxygen) Ion (“NAI” for short in this article) concentration. The daily temperature, precipitation, wind speed, sunshine hours, and relative humidity data of the Xingwen National Meteorological Station from 1999 to 2018, as well as the NAI data of Feiwu Cave station and Shoushan Lake station in Xingwen of 2018 were used in this study. Based on the analysis of the characteristics of basic meteorological elements, the index of climate comfort of human living environment and the NAI variation in Xingwen, the eco-tourism climate resources in this area were evaluated comprehensively. The results show that: The climate is mild, the precipitation is abundant and the seasonal variation trend of precipitation and heat is similar in the study area. The annual average temperature of this area is 17.8°C, the annual average precipitation is 1096 mm, the annual average precipitation days are 186 days, the annual average relative humidity is 81%, the annual average wind speed is 1.3 m/s, and the annual average sunshine hours are 999 h. The living environment comfort level reaches the “comfort” level for 6 months per year. In addition, the concentration of NAI in Xingwen remains at the highest level 7 throughout the year, and the rate of good air quality is extremely high. Overall, the study area has high-quality ecological climate resources that are conducive to the development of forest recuperation, leisure and vacation and other ecological tourism activities.
