Study on the Relationship between Acid Rain Characteristics and Weather Conditions in Nanchang

Based on the rainfall monitoring data and high altitude meteorological data,the present situation of acid rain pollution in Nanchang City was analyzed and the forming factors of acid rain were revealed. The results showed that acid rain in Nanchang had the characteristics of high acidity and frequency,and the pH value of rainfall reduced in recent years,belonging to sulfuric acid type,and the most serious acid rain pollution appeared in autumn and winter. The pH value of rainfall went up with the improvement of rainfall grade,and the increase of rainfall quantity had diluting effect on the rainfall acidity. High altitude meteorological conditions affected acid rain obviously,when the upper wind velocity was below 7 m/s,the frequency of acid rain was higher and its pH value was lower,with serious acid rain pollution,and it showed that upper wind had diluting effect on the horizontal transport of pollutants. The frequency of acid rain became higher with stronger inversion intensity. Moreover,the surrounding industrial areas had obvious effect on the formation of acid rain. Unstable meteorological conditions were beneficial to the horizontal and vertical diffusion of pollution in the lower atmosphere,reducing the effect of induced-acidity pollutants on a region.

Study on the Relationship between Characteristics of Haze Days and Lung Cancer in Nanchang City

Based on the conventional meteorological observation data during 1959-2014 and data of lung cancer cases of a third-grade classA tumor hospital in Nanchang City during 1997-2013,the annual variation of haze days in Nanchang City during 1959-2014 and its correlation with the related meteorological factors,as well as the characteristics of different types of lung cancer patients in Nanchang during 1997-2013 were analyzed. A correlation analysis method was used to study the correlation between the number of urban lung cancer patients and the number of haze days and fog days in each month in Nanchang. The lagging period of lung cancer was also discussed. The results show that the number of haze days in Nanchang rose since 1959,which is mainly related to the increase in the emissions of urban pollutants and the decrease of surface wind speed. The average age of female lung cancer was earlier than that of men. The number of men lung cancer patients was significantly larger than that of women. The number of urban lung cancer patients was obviously larger than that in rural areas. Haze had a great impact on the occurrence of lung cancer,with the lagging period of three years. Haze had a greater impact on urban women than urban men. The impact of haze on old people was greater than that of young and middle-aged people.

Impacts of Nanchang Metro on Accessibility of Public Transport Network and Fairness of Travel for Indemnificatory Housing Residents

Based on the GIS spatial analysis technology,this paper assessed the effects of Nanchang metro in improving the accessibility of public transport networks in different spatial patterns.Besides,from the perspective of transport fairness,this paper evaluated the fairness of allocation of transportation resources for indemnificatory housing residents.Then,it revealed the reasons for the welfare loss of indemnificatory housing residents in fast rail transit resources,so as to provide a reference for promoting the space adaptation of indemnificatory housing residents.The study found that(i)the subway has improved the accessibility of the urban public transport network in terms of travel time and accessibility,but it has a different effect on improving the accessibility of the public transport network.After crossing a certain transit time and distance,there is a weakening trend,showing a pattern of"central expansion-peripheral weakness".(ii)The relative improvement of the metro on the accessibility of public transport for indemnificatory housing residents is lower than the overall improvement efficiency,and the fairness of the redistribution of transportation resources of the indemnificatory housing residents is impaired.(iii)In order to prevent and reduce the problem of space mismatch between indemnificatory housing and rail transit,it can be achieved by planning the metro network according to the spatial characteristics of indemnificatory housing residents’activities,guiding the selection of sites for indemnificatory housing with the TOD model,and forming a mixed community by combining the indemnificatory housing construction with commercial housing,to guarantee fair resource allocation of indemnificatory housing residents.
