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.

Analysis of Characteristics of Lightning and Atmospheric Electric Field in Nanchang County

Based on ground observation,lightning locator and atmospheric electric field instrument data,the characteristics of lightning and atmospheric electric field in Nanchang County were analyzed. The warning effect of the atmospheric electric field instruments on lightning was studied,and the threshold of some atmospheric electric field instruments was adjusted according to the expectation of the warning accuracy rate. In Nanchang County,the annual number of thunderstorm days averaged 48. 6. Lightning mainly occurred from March to August,with a maximum of 8. 8 d in August. The lightning areas were mainly concentrated in the south,followed by the north,and the frequency of lightning in the middle was relatively low. The diurnal variation of lightning was obvious,and lightning happened most frequently from afternoon to evening. Five atmospheric electric field instruments were set up according to the lightning areas of Nanchang County. The average electric field intensity on a sunny day was 0. 06,0. 05,0. 16,0. 07,and 0. 17 kV/m respectively,with certain seasonal variations. The field intensity in June was the lowest in the whole year. The atmospheric electric field on a sunny day also had obvious diurnal variation characteristics,generally presenting the characteristics of double peaks and double valleys. The first peak of atmospheric electric field intensity appeared one hour later than that of relative humidity,and then the change trends were relatively consistent. After the adjustment,the warning accuracy rate of the atmospheric electric field instruments was greatly improved to meet the expectation.

The aging of the population in China has entered an accelerated stage. One of the goals for the micro transformation of old residential areas is to create a community space suitable for aging, promote outdoor activities and neighborhood social activities of the elderly, and thus improve the physical and mental health of the elderly. Starting from physiological, psychological and behavioral characteristics of the elderly,four characteristics of micro renovation of community public space for aging are analyzed. Qingshanhu Community is taken as research object. Based on the field survey of the elderly in the community, the problem of the insufficient current community space suitable for aging is summarized, and how to adapt to aging and micro transformation to promote healthy life of residents is analyzed, which could provide the reference for building an aging community.

Influence of Nanchang Metro Construction on Urban Traffic

With the acceleration of urbanization and motorization in China,traffi c congestion has becomethe“bottleneck”in the development of major cities in China.If the urban traffi c problem can not be solvedeffectively,it will seriously affect the sustainable development of big cities.However,to solve the traffi cproblems in big cities,it is necessary to have a forward-looking view,and to determine the developmentstrategy of transportation in big cities according to China’s national conditions and the characteristics ofmajor cities.China’s urban land resources are limited,and the land available for road traffi c is increasinglyscarce,and the contradiction between supply and demand of transportation is intensifi ed.Urban populationis gathering in big cities and megacities,and the demand for urban transportation will increase at a fasterspeed.Based on GIS spatial analysis technology,the accessibility of public transport for residents in themain urban area of Nanchang City before and after the metro opening is measured,and improvementbenefi ts of accessibility of metro in different spatial patterns are analyzed.This paper puts forward theimprovement measures of metro to Nanchang traffi c as the suggestions of Nanchang traffi c management.

基于DSM的城市公园对PM_(2.5)和PM_(10)的消减特征研究——以南昌市人民公园为例

【目的】PM_(2.5)、PM_(10)等空气颗粒物是城市空气首要污染物,在城市空气污染中占主导地位。了解固定外源下PM_(2.5)、PM_(10)在城市绿地的消减特征,可为城市阻控空气颗粒物、缓解空气污染提供有利依据。然而目前空气颗粒物的研究大多以点测定方式量化空间结构及植被类型对空气颗粒物的影响,对固定外源污染下PM_(2.5)、PM_(10)在城市绿地空间尺度上的影响机制研究较少。【方法】研究结合DSM与地统计学,以南昌市人民公园为例,探索城市公园阻隔外源污染的空间梯度效应及空间结构类型差异。利用克里金插值法对其空间分布特征进行可视化模拟;利用Arcgis和R语言等软件分析不同空间结构PM_(2.5)、PM_(10)的浓度差异。【结果】人民公园PM_(2.5)、PM_(10)的浓度在空间分布上趋势一致,均表现为以固定外源点为核心,浓度随距离增加呈极显著梯度递减的趋势,且在中部(约距外源点150~220 m处)消减效率最高,约为全园PM_(2.5)平均消减值的7.5倍,PM_(10)平均消减值的3.8倍;PM_(2.5)、PM_(10)受多种因子影响:与空气温度、距离(主导因子)显著负相关、与相对湿度显著正相关,且PM_(2.5)、PM_(10)对不同因子响应特征存在差异;城市公园不同绿地空间结构对PM_(2.5)、PM_(10)的消减及扩散作用差异显著,受其双重影响,PM_(2.5)、PM_(10)的浓度表现为水体>广场>树林>草坪,其中PM_(2.5)受影响更显著;此外,受各因子和绿地空间结构耦合影响,部分区域PM_(2.5)、PM_(10)分布异常。【结论】以固定外源点为核心,PM_(2.5)、PM_(10)浓度随距离增加呈极显著梯度递减的趋势,且在中部消减效率最高;PM_(2.5)、PM_(10)浓度与相对湿度显著正相关,与空气温度与距离显著负相关,其中PM_(10)对距离和相对湿度响应较为明显,而PM_(2.5)受空气温度影响较大;在随距离变化基础上,不同城市绿地空间结构对PM_(2.5)、PM_(10)消减和扩散作用差异导致了局部分布差异。

滨水生态驳岸对水体的净化效果研究——以南昌市象湖湿地公园为例

为研究滨水生态驳岸对水体的净化效果,本文以南昌市象湖湿地公园生态驳岸为例,通过重新构建生态驳岸植物群落等工程改造,监测和评价生态驳岸工程改造前后示范段的近岸水体净化效果。结果表明,改造前,区域内各水体的污染程度均较严重,原硬质驳岸、自然缓坡和木桩驳岸的近岸水质均为地表水Ⅴ类或Ⅴ类以下,以总氮为主要污染物,而总磷的污染程度较小。改造完成后,区域内的主要水体水质上升为地表水Ⅲ类,透明度明显增大;仅有局部的微小区域水质仍为Ⅴ类,但其污染指数已有明显降低。因此,生态驳岸的营建和滨水地带植物群落的合理布局,结合污染控制,能够较好地保护和重建水陆边缘地带的自然生态过程及岸栖生物栖息环境,有效地发挥其生态系统边缘效应,形成自然优美、生态功能持续稳定的湖泊湿地景观。

湘南起义的历史定位及与井冈山根据地的关系

1928年初爆发的湘南起义,是中国共产党在土地革命战争初期领导的具有一定规模的一次正规军与工农群众相结合的武装暴动。湘南起义不仅再度点燃了建军建政和开展土地革命的烽火,而且湘南起义部队奔赴井冈山,聚拢三支革命力量共同接受毛泽东、朱德等中国共产党人的领导,成为井冈山革命根据地的重要武装力量,为开辟中国革命道路、开创农村革命根据地进行了可贵探索。
