Understanding the driving mechanisms of crop suitability is critical for ensuring global food security, particularly in promoting the sustainable development of alpine agriculture and alpine civilizations. In contrast to climate factors, how anthropogenic adaptation measures affect crop suitability remains largely unknown. This overlooked mechanism may explain why climate-driven model simulations underestimate the upper altitude limit for highland barley compared with observed records. Here, we used two decades of site-based phenological observations on the Tibetan Plateau and biophysical modeling, finding that anthropogenic adaptation measures can expand suitable cropping limits. These measures mainly involve breeding genotypes with lower thermal units, which enhance the adaptability of highland barley phenology to cold climates. Such adaptation mechanisms clarify the conflict between thermal niche model predictions and the observed distribution of highland barley up to an altitude of 5000 m. Considering these mechanisms, we developed an explainable framework to predict the potential habitat of highland barley under current climates. Results showed that anthropogenic adaptation measures expanded the suitable cropping area for highland barley by 27 × 104 km2 and the upper altitude limit for highland barley could reliably increase by approximately 50 m. This observation-based evidence underscores the crucial roles of anthropogenic adaptation measures in expanding suitable cropping limits of crops and highlights its importance for supporting food security and simulating accurate crop suitability. © 2025 Science China Press

A clear understanding of the relationships among multiple ecosystem services(ESs) is the foundation for sustainable urban ecosystem management. Quantitatively identifying the factors that influence ES trade-offs and synergies can contribute to deepening ES research, from knowledge building to decision making. This study simulated soil conservation, water yield and carbon sequestration in Beijing, China, from 2015–2018. The spatial trade-offs and synergies of these three ESs within the five major river basins in Beijing were explored using geographically weighted regression. Furthermore, geographical detector was applied to quantitatively identify the driving mechanism of the environmental factors for the ES trade-offs and synergies. The results show the following:(1) the spatial relationships between soil conservation and water yield, as well as between water yield and carbon sequestration, were mainly trade-offs. There was a spatial synergy between soil conservation and carbon sequestration.(2) Regarding the spatial trade-off/synergy between soil conservation and water yield in Beijing, the dominant influencing factor was temperature/elevation, and the dominant interactions of the spatial trade-off and synergy between these two ESs in Beijing and the Chaobai River Basin are all manifested in the superposition of precipitation and potential evapotranspiration, temperature, and elevation.(3) Topographic factors were the dominant factors influencing the spatial relationship between soil conservation and carbon sequestration in Beijing and its five major river basins. As a result of the distribution of water systems and hydrological characteristics of the basins, differences were observed in the effects of different combinations of interaction factors on the spatial relationship between these two ESs in different basins.(4) Temperature had the strongest explanatory power in terms of the spatial trade-offs and synergies between water yield and carbon sequestration.

Against the background of global climate change, the increasing heat health risk from the combined effect of changes in high temperature, exposure, vulnerability, and other factors has become a growing *** the low number of temperature observation stations is insufficient to represent the complex changes in urban heatwaves, and subdistrict-scale(town, township, neighborhood committee, and equivalent) heat health risk and adaptability assessments are still limited. In this study, we built daytime and nighttime high-temperature interpolation models supported by data from 225 meteorological stations in *** models performed well at interpolating the cumulative hours of high temperature and the interpolation quality at night was better than that during the day. We further established a methodological framework for heat health risk and adaptability assessments based on heat hazard, population exposure, social vulnerability, and adaptability at the subdistrict scale in Beijing. Our results show that the heat health risk hotspots were mainly located in the central urban area,with 81 hotspots during the day and 76 at night. The average value of the heat health risk index of urban areas was 5.60 times higher than that of suburban areas in the daytime,and 6.70 times higher than that of suburban areas in the night. Greater population density and higher intensity of heat hazards were the main reasons for the high risk in most heat health risk hotspots. Combined with a heat-adaptive-capacity evaluation for hotspot areas, this study suggests that 11high-risk and low-adaptation subdistricts are priority areas for government action to reduce heat health risk in policy formulation and urban development.

Large regional differences and uneven regional development are fundamental challenges for China. Balanced regional development is an important issue in research on development geography. This study reviews the course of balanced regional development in China and summarizes its characteristics in each period. The results show that inter-regional development in China has undergone successive periods of balanced and unbalanced development. Each period has enhanced social development and contributed to a more balanced regional development. This paper discusses the scientific connotation of balanced regional development, and invokes sustainable development theory to argue that we should pay attention to the differences in resource endowments among regions, and solves the imbalance among the economy, humans, and nature to promote the spatial balance of regional development and green development for better coordination between economy and ecology. The balanced promotion of the well-being of people in each region is the ultimate goal of balanced regional development. We then use concepts from development geography to examine China’s path of balanced regional development from the three perspectives of society, the economy, and ecology. Suggestions are also provided for the balanced development of China’s regions and the improvement of public well-being.

Comprehensive understanding of guest compound intercalated layered double hydroxides: Design and applications in removal of potentially toxic elements

引用

Critical Reviews in Environmental Science and Technology 2023年第4期53卷 457-482页

作者： Cui, Shihao Peng, Yutao Yang, Xiao Gao, Xing Guan, Chung-Yu Fan, Beibei Zhou, Xue Chen, Qing Beijing Key Laboratory of Farmland Soil Pollution Prevention and Remediation College of Resources and Environmental Sciences China Agricultural University Beijing China School of Agriculture Sun Yat-sen University Guangdong Shenzhen China Key Laboratory of Land Surface Pattern and Simulation Institute of Geographic Sciences and Natural Resources Research Chinese Academy of Sciences Beijing China State Key Laboratory for Pollution Control and Reuse School of Environmental Science and Engineering Tongji University Shanghai China Department of Environmental Engineering National I-Lan University Yilan Taiwan

Layered double hydroxides (LDHs) and LDHs-derived materials are emerging as potential engineered adsorbents for the protection of water environment. Particularly, LDHs intercalated with different guest compounds (GC-LDHs), which differ from traditional interlayer anions (such as Cl−, SO42−, NO3−, CO32−, and PO43−), are widely reported by recent studies showing their promising multifunctional roles in water purification. Herein, this review systematically presents the synthesis methods and characterization techniques of GC-LDHs and their application as adsorbents in removing potentially toxic elements (PTEs) from the aqueous phase. This review also elaborates on the important roles of complexation, chelation, precipitation, isomorphic substitution, and ion exchange in the process of PTE removal by GC-LDHs. Among them, compared with PTE cations, ion exchange is an additional mechanism for the removal of PTE oxyanions by GC-LDHs. Furthermore, the influence of pH, ionic strength, temperature, physiochemical properties of original LDHs and guest compounds on the GC-LDHs adsorption performance are also summarized. Finally, the development trends and future challenges related to GC-LDHs are proposed. © 2022 Taylor & Francis Group, LLC.
