“…This area is affected by the warm southeast monsoon in summer and the cold continental monsoon in winter, causing seasonal variability in precipitation [34,35]. The annual average precipitation in this area is about 740 mm, but nearly 43% of it is concentrated in summer, with frequent high-intensity rainstorms [36,37]. The area of the Guanzhong plain accounts for 26.94% of the area of Shaanxi province, but the population and GDP of Guanzhong plain account for 63.35% and 62.35% of population and GDP of Shaanxi province respectively [38].…”

“…In this research, the respondents' basic information for the two communities was divided into three different parts, shown in Figure 3, with which the investigation of the residents' characteristics of age, educational background and occupation informed the next analysis. Four age cohorts were established ≤18, [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]36-60 and ≥61. The proportion of the age group 18 and 61 were 9.6% and 1.9% in Baihualinjian, followed by 0.9% and 0% in Tongdejiayuan, illustrating few very young and very old respondents.…”

Comparative Assessment of Sponge City Constructing in Public Awareness, Xi’an, China

Climate change and urbanization are causing increasingly frequent urban flooding in countries around the world. Various innovative approaches have emerged to address this challenge. In China, the Sponge City was first proposed in 2012 to achieve an urban hydrological balance through natural storage, natural infiltration and natural purification. This article presents a comparative investigation (using a survey method) of new and old communities in Xixian New District and Xi’an in September 2021 to investigate public awareness of the Sponge City and understand levels of satisfaction and acceptance. Individuals of the same age or education residing in the Sponge City generally know more about the Sponge City and were more willing to accept it than those in traditional cities. Moreover, the residents of Sponge City understand the Sponge City concept well, with a majority of the respondents (71.82%) expressing clear understanding on the conception of Sponge City. However, residents in a traditional city exhibited much less understanding of the concept (44.24%). Furthermore, for those living in the same area, people who are younger or have higher education exhibited a clearer understanding of and acceptance of the Sponge City and local government. In this survey, the average scores (assign values to the different responses, then average and percent it) of respondents in Xixian New District with master’s degrees, bachelor’s degrees and high school degrees or below were evaluated at 76.88, 67.94 and 62.15, respectively, compared to 62.07, 50.18 and 50.78 in Xi’an. Lastly, we found that differences in living environment have a significant influence on residents’ perceptions. Residents living in the Sponge City are generally satisfied with the travel and living conditions and greatly support the local government. Meanwhile, this study will help relevant authorities pay more attention to residents’ opinions and help them to formulate policies to spread the concept of Sponge City and encourage residents’ participation.

Understanding the seasonal patterns and in uencing factors of nitrogen atmospheric deposition is essential to evaluate human impacts on the air quality and nitrogen biogeochemical cycle. However, evaluation of the nitrogen deposition ux, especially in South America agricultural regions, has not been fully investigated. In this paper, we quanti ed the atmospheric wet deposition uxes of total dissolved nitrogen (TDN), dissolved organic nitrogen (DON) and dissolved inorganic nitrogen (DIN), in a region with agricultural and livestock predominance in the Southern Minas Gerais region, Brazil, from May 2018 to April 2019. Deposition uxes of nitrogen species in the wet season (October -March) were on average 4.8 fold higher than dry season, which revealed signi cant seasonal variations driven largely by the seasonality of rainfall and agricultural operations. We also found high NO 3 − /NH 4 + ratios (average = 8.25), with higher values in dry season (NO 3 − /NH 4 + = 12.8) in comparison with wet season (NO 3 − /NH 4 + = 4.48), which revealed a higher relative contribution of NO x emissions from tra c sources in dry season. We also estimated the in uence of atmospheric deposition of inorganic nitrogen (N-DIN) on environmental ecosystems, being 2.01 kgNha − 1 yr − 1 with potential risk of acidi cation and eutrophication of 30%.Therefore, attention should be paid to the role of wet atmospheric deposition of nitrogen as a source of nitrogen environmental pollution in agricultural regions.
