“…Research methodologies that have been employed in relation to impervious surfaces include the land use approach (Sharma, Ghosh, & Joshi, 2013) and accessing the population (Lu & Weng, 2006). Urban planning and land use approaches (Chen & Yu, 2016;Xiao et al, 2018), urban green space planning (Zhang et al, 2017) and also urban environmental assessment Trivero et al, 2012) have been used in urban impervious surface research. Sinha et al (2016) found that urban builtup land applies high reflection on SWIR and TIR wavelengths and low reflection on NIR.…”

Impervious surface is one of the major land cover types of urban and suburban environment. Conversion of rural landscapes and vegetation area to urban and suburban land use is directly related to the increase of the impervious surface area. The impervious surface expansion is straight-lined with decreasing green spaces in urban areas. Impervious surface is one of indicator for detecting urban heat islands. This study compares various indices for mapping impervious surfaces using Landsat 8 OLI imagery by optimizing the different spectral characteristics of Landsat 8 OLI imagery. The research objectives are (1) to apply various indices for impervious surface mapping and (2) identifies impervious surfaces in urban areas based on multiple indices and provide recommendations and find the best index for mapping impervious surface in urban areas. In addition to utilizing the index, land use supervised classification method, maximum likelihood classification used for extracting built-up, and non-built-up areas. Accuracy assessment of this research used field data collection as primary data for calculating kappa coefficient, producer accuracy, and user accuracy. The study can also be extended to find the land surface temperature and correlate the impervious surface extraction data with urban heat islands.

“…A variety of methods for air quality research are put forward by domestic and foreign scholars: (1) using fuzzy logic to deal with air quality indicators [24] and neural networks to forewarn air pollution [25] and so on. e AQBI (Air Quality Balance Index) is used to assess air quality and environment in a three-dimensional diffusion model [26], in addition to distance discrimination, matter element analysis, breakpoint regression analysis, parting model, and so on [27]; (2) in the background of the development, we use the statistics of Weibo (microblog), DMSP/OLS (Defense Meteorological Satellite Program/Operational Linescan System), "World Map," and other methods to study on the urban air quality [28][29][30].…”

Based on the monthly data of 12 months in 30 major cities and combined with the monthly data of the air quality index (AQI) in 30 major cities, this paper analyzed the quality of human settlements in 2015 with the ArcGIS spatial analysis method. On the basis of the quality of air in this analysis, the coupling degree of the five great systems in these human settlements was also calculated. e finding shows that (1) according to the spatial distribution of the human settlements quality index in the main cities, the quality of urban human settlements was gradually decreased from the coastal regions to northwest inland regions, presenting an overall look that the quality was high in the south and low in the north, which converged to the change of the air quality; (2) the human settlements quality index apparently changed with season variation. A significant difference was found in the fourth quarter, and the biggest deviation among cities in China was up to 0.680, while the smallest deviation in the second quarter was 0.448; and (3) on the basis of factors that influenced the quality index, related kinds of norms in the main cities were built in the five great systems of human settlements, and the evaluated coupling degree between the five systems was at the antagonistic stage.

In addition to using such methods to characterize the amount of pollution level in selected areas, the enhanced air quality index (AQI) can also be used 47 48 49 , such as in the form of pollutant concentration values divided by their standards 50 . The air pollution monitoring networks have been greatly improved worldwide in recent years with increased and updated sites 51 52 .…”

Although air quality monitoring networks have been greatly improved, interpreting their expanding data in both simple and efficient ways remains challenging. Therefore, needed are new analytical methods. We developed such a method based on the comparison of pollutant concentrations between target and circum areas (circum comparison for short), and tested its applications by assessing the air pollution in Jing-Jin-Ji, Yangtze River Delta, Pearl River Delta and Cheng-Yu, China during 2015. We found the circum comparison can instantly judge whether a city is a pollution permeation donor or a pollution permeation receptor by a Pollution Permeation Index (PPI). Furthermore, a PPI-related estimated concentration (original concentration plus halved average concentration difference) can be used to identify some overestimations and underestimations. Besides, it can help explain pollution process (e.g., Beijing’s PM2.5 maybe largely promoted by non-local SO2) though not aiming at it. Moreover, it is applicable to any region, easy-to-handle, and able to boost more new analytical methods. These advantages, despite its disadvantages in considering the whole process jointly influenced by complex physical and chemical factors, demonstrate that the PPI based circum comparison can be efficiently used in assessing air pollution by yielding instructive results, without the absolute need for complex operations.
