Mobile Monitoring of Urban Air Quality at High Spatial Resolution by Low
Mobile monitoring of urban air quality at high spatial resolution by low-cost sensors: Impacts of COVID-19 pandemic lockdown Shibao Wang1, Yun Ma1, Zhongrui Wang1, Lei Wang1, Xuguang Chi1, Aijun Ding1, Mingzhi Yao2, Yunpeng Li2, Qilin Li2, Mengxian Wu3, Ling Zhang3, Yongle Xiao3, Yanxu Zhang1 5 1School of Atmospheric Sciences, Nanjing University, Nanjing, China 2Beijing SPC Environment Protection Tech Company Ltd., Beijing, China 3Hebei Saihero Environmental Protection Hi-tech. Company Ltd., Shijiazhuang, China Correspondence: Yanxu Zhang ([email protected]) Abstract. The development of low-cost sensors and novel calibration algorithms provides new hints to complement 10 conventional ground-based observation sites to evaluate the spatial and temporal distribution of pollutants on hyperlocal scales (tens of meters). Here we use sensors deployed on a taxi fleet to explore the air quality in the road network of Nanjing over the course of a year (Oct. 2019–Sep. 2020). Based on GIS technology, we develop a grid analysis method to obtain 50 m resolution maps of major air pollutants (CO, NO2, and O3). Through hotspots identification analysis, we find three main sources of air pollutants including traffic, industrial emissions, and cooking fumes. We find that CO and NO2 concentrations show a pattern: 15 highways > arterial roads > secondary roads > branch roads > residential streets, reflecting traffic volume. While the O3 concentrations in these five road types are in opposite order due to the titration effect of NOx. Combined the mobile measurements and the stationary stations data, we diagnose that the contribution of traffic-related emissions to CO and NO2 are 42.6 % and 26.3 %, respectively. -
Spatial Distribution Pattern of Minshuku in the Urban Agglomeration of Yangtze River Delta
The Frontiers of Society, Science and Technology ISSN 2616-7433 Vol. 3, Issue 1: 23-35, DOI: 10.25236/FSST.2021.030106 Spatial Distribution Pattern of Minshuku in the Urban Agglomeration of Yangtze River Delta Yuxin Chen, Yuegang Chen Shanghai University, Shanghai 200444, China Abstract: The city cluster in Yangtze River Delta is the core area of China's modernization and economic development. The industry of Bed and Breakfast (B&B) in this area is relatively developed, and the distribution and spatial pattern of Minshuku will also get much attention. Earlier literature tried more to explore the influence of individual characteristics of Minshuku (such as the design style of Minshuku, etc.) on Minshuku. However, the development of Minshuku has a cluster effect, and the distribution of domestic B&Bs is very unbalanced. Analyzing the differences in the distribution of Minshuku and their causes can help the development of the backward areas and maintain the advantages of the developed areas in the industry of Minshuku. This article finds that the distribution of Minshuku is clustered in certain areas by presenting the overall spatial distribution of Minshuku and cultural attractions in Yangtze River Delta and the respective distribution of 27 cities. For example, Minshuku in the central and eastern parts of Yangtze River Delta are more concentrated, so are the scenic spots in these areas. There are also several concentrated Minshuku areas in other parts of Yangtze River Delta, but the number is significantly less than that of the central and eastern regions. Keywords: Minshuku, Yangtze River Delta, Spatial distribution, Concentrated distribution 1. -

Firstly, using Gephi software, we constructed the public bicycle networks of different urban areas based on the real-time data of the Nanjing public bicycle system. Secondly, we analyzed and compared degree, strength, radiation distance, and community structure of the networks to understand the internal relations of the public bicycle system. The results showed that there were many stations with low usage of public bicycles. Furthermore, there was a geographical division between high-demand and low-demand areas for public bicycles. The usage of public bicycles at a station was not only related to land use but also related to the usage of bicycles at stations nearby. -

The binary structure of the floodplain in the reaches of the Yangtze River is obvious and has unique hydrogeological features. In this paper, the hydrogeological survey of the floodplain area is carried out. It is found that the permeability coefficient of the floodplain area is gradually increasing from top to down, and is larger than that of the similar layer in other areas. The horizontal and vertical permeability coefficients are not much different. This hydrological survey results of this paper provide a certain reference for similar dewatering projects in the floodplain area of the lower reaches of the Yangtze River. 1 Introduction The lower reaches of the Yangtze River have a wide river 2 Geological conditions surface and a slow flow velocity.

SPATIAL DISTRIBUTION of AFFORDABLE HOUSING PROJECTS in NANJING, CHINA JIA YOU, SUN SHENG HAN and HAO WU Abstract Introduction
SPATIAL DISTRIBUTION OF AFFORDABLE HOUSING PROJECTS IN NANJING, CHINA JIA YOU, SUN SHENG HAN and HAO WU Melbourne School of Design, the University of Melbourne, Australia Abstract Traditional location theory matches location choices and stakeholder (e.g. developer, user) decisions in a competitive efficient market framework. Developer profit and land value are directly linked to the location characteristics of the property development project. Recent progress in theory & empirical studies has indicated the imperfection of the market e.g. market competition is monopolistic in the urban property sector. Urban affordable housing is typically under direct government intervention e.g. planning, finance and taxation benefits and/or restrictions. We investigate the Nanjing (China) affordable housing sector. Data is collected from all existing affordable housing projects (2002-2010) in the city. Semi-structured interviews and site visits were conducted in 2009 and 2010. Through the study of the Nanjing affordable housing case, we found that (1) the site (location) selection of most projects has shown positive relationship with the general land value ingredient of Nanjing; (2) site selection is heavily influenced by nearby urban development projects, which cause strong resettlement demand; (3) due to the local government’s dual role, they consider the economic factors, such as the surrounding conditions of the sites, and the pervious use and compensation fees. We argue that demand and institutional factors place important role in determining the location of affordable housing projects in Nanjing. Keywords: Location distribution, government, allocation, affordable housing, Nanjing Introduction Affordable housing in China is a central government initiative to housing reform, which is a crucial part of economic reform started in 1978. -
