“…Studies have shown that global warming may increase the frequency and intensities of heatwaves and urban heat island effects, , such that the impacts of temperature-dependent AVOC emissions on ozone may become more pronounced in the future. Other underestimated or unrepresented natural and anthropogenic emissions of ozone precursors, such as soil-NO x emissions and emissions associated with urban greening practices, − may also cause complex ozone-temperature sensitivities. These linkages between air pollution and meteorology should be considered in our projection of long-term air quality trends to better inform the long-term emission reduction goals.…”

The evaporative emissions of anthropogenic volatile organic compounds (AVOCs) are sensitive to ambient temperature. This sensitivity forms an air pollution-meteorology connection that has not been assessed on a regional scale. We parametrized the temperature dependence of evaporative AVOC fluxes in a regional air quality model and evaluated the impacts on surface ozone in the Beijing−Tianjin−Hebei (BTH) area of China during the summer of 2017. The temperature dependency of AVOC emissions drove an enhanced simulated ozone-temperature sensitivity of 1.0 to 1.8 μg m −3 K −1 , comparable to the simulated ozone-temperature sensitivity driven by the temperature dependency of biogenic VOC emissions (1.7 to 2.4 μg m −3 K −1 ). Ozone enhancements driven by temperature-induced AVOC increases were localized to their point of emission and were relatively more important in urban areas than in rural regions. The inclusion of the temperature-dependent AVOC emissions in our model improved the simulated ozone-temperature sensitivities on days of ozone exceedance. Our results demonstrated the importance of temperature-dependent AVOC emissions on surface ozone pollution and its heretofore unrepresented role in air pollution−meteorology interactions.

“…Besides, green infrastructure serves as a significant source of ESs supply, offering various benefits such as cooling (Li et al 2022;Zhou et al 2021) and the enhancement of air quality (Yu et al 2022) within urban areas. It's worth noting that studies have revealed that using low-resolution data can lead to underestimations in green space assessment (Qian et al 2020).…”

Context Rapid urbanization has brought substantial changes in structure and function of ecosystems, significantly impacting ecosystem services (ESs) supply and demand, and thereby landscape sustainability. Objectives Revealing differences impacts of urbanization on ESs supply and demand across old, new and non-urban areas. Methods First, we quantified the supply and demand of four ESs, namely food production (FP), water retention (WR), carbon sequestration (CS), and habitat quality (HQ) within the ChangZhuTan urban agglomeration from 2000 to 2020. Then impacts of urbanization on ESs supply–demand ratio (ESDR)were investigated by OLS linear regression, alongside assessing sensitivities with Random Forest models. The differences in these impacts and sensitivities were compared across old, new, and non-urban areas, utilizing the proportional cover of construction land (CLP), population density (PD), and GDP density (GDPD) as urbanization indicators. Results (1) Urban expansion resulted in the increase of areas with low ESs supply but high demand, and thereby increased ESs deficits in urban edges. (2) CLP, PD and GDPD mostly had negative associations with ESDRs, especially in non-urban areas. Notably, they had positive impacts on ESDRs of CS and WR in old urban areas. (3) The sensitivity of ESDRs to urbanization differs in three areas. ESDRs were sensitive to GDPD and CLP in old and new urban areas, with only CLP emerging as the most sensitive indicator in non-urban areas, indicating the necessity for place-based strategies. Conclusions Urbanization exerted diverse impacts on ESDRs across old, new, and non-urban areas, and showed significantly negative impacts in new urban areas. This underscores the need for enhanced landscape management to balance ESs and urbanization. Results from this study can enhance understanding of relationships between urbanization and ESs, and provide insights for landscape sustainability in an increasingly urbanizing planet.

“…The spatial concentration of a large number of industrial enterprises leads to an increase in the total amount of industrial pollutants discharged in the region and an increase in the degree of environmental damage (Li H et al, 2020;Panda and Siva Nagendra, 2018), and is therefore measured by the ratio of the number of industrial enterprises above the scale to the area of the jurisdiction (Lin et al, 2022). 7) Vegetation index (NDVI): in this paper, the normalized difference vegetation index (NDVI) is used to measure the level of urban greening, which may have both positive and negative effects on air quality; on the one hand, green areas as carbon sinks can play a role in purifying the air, and on the other hand, excessive investment in urban green areas may crowd out environmental protection expenditures in other areas (Yu et al, 2022).…”

Poverty eradication and environmental protection as the two global goals of sustainable development. China’s poverty alleviation policy attempts to achieve green development in poverty-stricken areas by eliminating poverty while also promoting environmental protection. Since the Poverty-stricken counties on the Qinghai-Tibet Plateau also have the dual attributes of ecological degradation and ecological fragility, it is of great significance to study the impact of poverty alleviation policy on their environment. In this research, taking poverty alleviation policy as the entry point, based on panel data and Remote Sensing Ecological Index for poverty-stricken counties on the Qinghai-Tibet Plateau from 2011 to 2019, and using the difference-in-differences (DID) method to verify the impact of policy on environmental quality. The main findings of the study were: 1) The poverty alleviation policy has a significant improvement effect on the ecological environment quality of counties in the Qinghai-Tibet Plateau region, and this conclusion still holds in a series of robustness tests using methods including the changing sample size method and the variable replacement method. Moreover, the policy effect has a certain time lag and its effect persists in the long term; 2) It is mainly due to the increased level of government public expenditure and the easing of government financial pressure that has contributed to the improvement of environmental quality in poverty-stricken areas; 3) Policy heterogeneity suggests that industrial poverty eradication policies are more conducive to promoting synergistic economic and environmental development in poverty-stricken areas.
