“…In the past 20 years, Xi'an has undergone rapid urbanization, with the resident population increasing from 7.41 million in 2000 to 12.95 million in 2020, and the urbanization rate increasing from 42.1% to 79.5% (Sun et al 2023). This study focuses on the six main urban areas in Xi'an, as shown in Fig.…”

The continuous process of urbanization and climate change has led to severe urban heat island (UHI) effects. Constructing parks with cooling capabilities is considered an effective measure to alleviate UHI effects. However, most studies only quantify the cooling effect from a maximum value perspective, lacking a measure of temperature diffusion in space. This study combines the perspectives of maximum value and accumulation to define a cold island index, quantifying the cooling effect of 40 urban parks in the main urban area of Xi'an city. The results show that, on average, urban parks can reduce the surrounding environment by approximately 2.3℃, with a cooling range of about 127.1ha, which is three times the park area. Different factors drive the measurement of the cooling effect using different cold island indexes, but all indexes are highly correlated with green space area. There are significant differences in the cooling effect among different types of parks, and overall, ecological parks have the best cooling effect. The directional spread of internal cold islands in parks is most related to park shape, while external spread is related to surrounding green spaces. The research results have practical value in the construction of parks with cooling effects and the sustainable development of cities in urban planning processes..

“…It is estimated that more than one billion people will live in cities in China by 2030 ( Wang et al, 2018 ). Although urbanization provides people with education, medical, and other conveniences, it is associated with negative effects such as environmental pollution ( Sun, Wang & Zhu, 2023 ; Yue et al, 2020 ). Therefore, rapid urbanization has a profound and lasting impact on local and even national public health ( Li et al, 2016b ).…”

Background With the rapid urbanization in many countries, more attention is being paid to the relationship between urbanization and mental health, especially depression. However, in countries with rapid urbanization, few empirical studies exist on the relationship between urbanization and adolescent depression. Methods Nationally representative survey data from the China Family Panel Studies in 2012, 2016 and 2018 were used. Data of 1,588 adolescents were obtained from 25 provinces. Depression was measured using the Center for Epidemiology Studies of Depression 20-item score. The urbanization rate was obtained from the National Bureau of Statistics of China. The generalized estimating equation was used to estimate the statistical relationship. Results The participants’ mean age at baseline was 15 years, and 51.2% (813/1,588) of participants were male. After adjusting for all covariates (gender, age, ethnicity, level of education, marital status, urban/rural areas, body mass index, self-rated health, academic pressure, smoking, drinking and exercise), the rate of urbanization was monotonically and negatively associated with adolescent depression (odds ratio 0.34, 95% CI [0.14–0.79]). Compared with female adolescents, male adolescents had a lower risk of depression (odds ratio 0.80, 95% CI [0.67–0.97]). Conclusion In the context of China, urbanization has a positive effect on the mental health of adolescents. Female adolescents are more likely to experience depression than male adolescents.

“…Urban agglomeration regions have become pivotal areas of global population concentration, economic intensity, and high socio-cultural development [3]. The rapid expansion of urban agglomerations has widespread and far-reaching impacts on economic, social, and ecological development of peri-urban areas (PUAs) [4,5]. In particular, the large-scale and diversified demand for agricultural products in cities has driven the shifts from traditional monoculture farming (mainly grain crops) to multifunctional modern agriculture [6,7].…”

Agricultural transition and specialization in PUAs have reshaped the ecological landscape, economic structure, and rural cultural values worldwide. There is a gap in how to analyze the linkages of ecosystem services (ES) and human well-being (HWB) and how to clearly identify the differences on the dimension (primary concerns) of HWB from a comprehensive perspective. Thus, we selected three typical agricultural transformation modes in the Xi’an metropolitan zone in China, employing social surveys, field mapping, ecosystem service assessment methods, and qualitative analysis methods, and proposed an analytical framework from a comprehensive perspective of “ecological-social-cultural” contexts to examine the changes and mechanism between ES and HWB. The results indicated the following: (1) Agricultural transition has driven the changes not only in ecological landscape, agricultural structure planting and practice modes, and rural economic structure, but also the shift in rural social relationships and cultural values together restructured rural society during agricultural specialization. (2) Due to triggering by the agricultural transition and specialization, great changes occurred in “ecological-social-cultural” contexts in PUAs, the changes of HWB not only reflected in its degree (level), but more importantly, in its dimension (primary concerns). (3) With agricultural transition and specialization, the total value of ES increased, while the HWB rose in three transition modes. (4) The analytical frameworks proposed in the study are suitable to analyze the mechanisms of ES and HWB, and helpful to address the issues on the relation of ES to HWB inevitably being combined with the nature–land system. The approach proposed in the study on distinguishing the differences among the dimensions of well-being based on grounded theory could clearly identify the differences among different “ecological- social-cultural” contexts.
