Atmosphere evaluation systems: Wu calculates the regional climate comfort index by using meteorological situations, like air temperature and relative humidity [24]. Yang establishes the comprehensive evaluation technique of green human settlements and ecological atmosphere elements, like atmospheric, urban kind, and temperature atmosphere [25,26]. Tang constructs a comprehensive evaluation technique focusing on living situations, urban ecological atmosphere, and social economy [27]. Sykes attaches significance to all aspects of urban livable environment, which includes the environment of socio-economy, living, and ecology [28]. The balance among the built residential atmosphere plus the natural atmosphere is often a crucial link in urban arranging and construction, and it is also an essential foundation and guarantee for improving the well-being of residents [291]. Evaluation of urban human settlements at property and abroad largely makes use of the complete index method to measure the regional benefits and disadvantages. Among them, the meteorological information of urban human settlements are essential for sustainable improvement [32] because they are able to quantify and analyze the adjust of urban human settlements greenness, at the same time as evaluate the urban disaster resilience and urban environmental cleanliness [11]. In addition, the atmospheric environment also exists in the evaluation factor of urban systems [33], which can quantitatively evaluate the quality and the livability of urban organic and cultural environments [34,35], theoretically guiding the building of a livable city [36].Land 2021, ten,3 ofWith the progress of geography and connected disciplines, quite a few Resolvin E1 Endogenous Metabolite modern remote sensing and computer technologies are applied to human settlements assessments to provide standard assistance for environmental quality assessment. In current years, using the combined data of satellite image, space, and also other multi-sources as the frontier, mainstream techniques, such as fuzzy mathematics, fuzzy measure theory, and vector operator have been adopted. Helpful information such as disaster prevention and arranging, surrounding regional linkage, and management policies happen to be determined, promoting the establishment, evaluation, and model discussion of human settlements program indicators [379]. The correlation involving air quality and surrounding regions makes the hyperlink involving human settlements and also the surrounding cities attract people’s attention [40,41]. Emedastine (difumarate) Agonist Scholars at home and abroad combine traditional and emerging strategies and technologies, formulate evaluation indicators, and establish mathematical models to conduct study, evaluation, and prediction of spatialtemporal variations [42,43]. They focus on urban organizing and future analysis in the point of view of livability plus the sustainability of human settlements, so as to study the relationship amongst air excellent and urban overall health [43,44]. At present, there are handful of research on examining a vital issue from a single viewpoint, formulating targeted policies and measures to serve a wide variety of social groups so as to defend existing urban bases [446]. To sum up, as a way to efficiently enhance the well being of residents and the quality of living atmosphere, as well as resolve the problems of human settlements, this paper takes the basic wants of urban residents as the core and selects the air-oriented evaluation method, which can be a unique indicator mixture variety, to be able to study the spatial-temporal differentiation of human se.
