A novel entropy-based method for quantifying urban energy demand aggregation: Implications for urban planning and policy

Sustainable Cities and Society, Journal Year: 2024, Volume and Issue: 103, P. 105284 - 105284

Published: Feb. 19, 2024

Urban energy demand aggregation (UEDA) is a key aspect of urban sustainability, as it can help to improve the efficiency systems and reduce their environmental impacts. However, UEDA challenging task, involves aggregating heterogeneous diverse demands individual buildings into collective at given spatial scale. This paper proposes novel entropy-based method for that quantifies information loss or distortion resulting from this process. The also identifies optimal scale minimizes distortion, evaluates quality reliability results using metrics. We apply case study Chicago, where we estimate analyze 10 scales, ranging 1.5 km 15 km, different types sources. calculate entropy each source, compare with building characteristics ZIP codes. assess metrics, such gain ratio normalized mutual information. Our show scales reveal patterns relationships demand, choosing an appropriate enhance accuracy UEDA. there balances preservation reduction, may vary depending on type source context. findings contribute field sustainability by developing perspective dynamics, revealing complexity diversity systems, population, land use, transportation, demand.

Forests are an important part of natural resources and play role in carbon sinks. We measured sinks provincial forest parks using data from four inventory surveys China the stock expansion method. Carbon emissions tourism were also estimated energy statistics park data. On this basis, spatial analysis was used to summarize temporal evolution balance influencing factors. The results show following: (1) With passage time, all provinces have increased different degrees, national 1,071,390.231 (million tons) 2003 286,255,829.7 2018; spatially, distribution is uneven, with overall high south low north, a east west.

Can digital literacy promote farmers’ cultivated land quality protection behaviors?

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(2), P. e0319050 - e0319050

Published: Feb. 27, 2025

Cultivated land is the most valuable agricultural resource and important factor of production. The protection cultivated quality not only foundation national food security but also a strategic issue related to sustainable development economy society as whole. This paper uses survey data from Jiangxi Province's "Double Hundred Thousand" in 2023 empirically analyzes impact digital literacy on farmers' behaviors its mechanism by using O-probit model mediating effect model. results show that can effectively promote behaviors. Furthermore, indirectly through cognition use ability. Heterogeneity analysis indicates farmers are more inclined participate In context better soil fertility conditions higher literacy. Therefore, it necessary continuously improve farmers, their awareness protection, strengthen

Long-Term (2015–2024) Daily PM2.5 Estimation in China by Using XGBoost Combining Empirical Orthogonal Function Decomposition

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(9), P. 1632 - 1632

Published: May 4, 2025

Fine particulate matter (PM2.5) has garnered significant scientific and public health concern owing to its capacity for deep penetration into the human respiratory system, presenting risks. Despite implementation of strict environmental policies in China over past decade reduce PM2.5 levels, long-term concerns remain a serious issue. Our study aims provide high-quality, seamless daily dataset covering years 2015 2024. A two-step estimation model is established based on machine learning algorithm spatio-temporal decomposition method. First, we utilize XGBoost (EXtreme Gradient Boosting) address gaps MAIAC (Multi-Angle Implementation Atmospheric Correction) AOD (Aerosol Optical Depth), with R2/RMSE (coefficient determination/Root Mean Square Error) 0.67/0.2678 compared AERONET Robotic Network) AOD. Then, novel approach by integrating EOF (Empirical Orthogonal Function) introduced estimation. The integration allows incorporation entire meteorological field information model, significantly enhancing accuracy: spatial CV (cross-validation)-R2 improved from 0.8340 0.8935, CV-RMSE reduced 13.8177 11.0668. Leveraging newly produced dataset, analyze variations across decomposition, particularly noting that levels eastern anthropogenic intensive regions continuously declined 2020, fluctuated steadily during 2020–2024. This research underscores critical need sustained effective air quality management strategies China.

Uncovering the black box of public data: the contribution of open government data to air pollution control

Frontiers in Environmental Science, Journal Year: 2025, Volume and Issue: 13

Published: May 15, 2025

Enhancing data elements to support environmental governance is a key initiative for promoting digital transformation and ecological development. This study constructs quasi-natural experiment based on panel of Chinese cities from 2010 2021, using the staggered rollout open government (OGD) platforms evaluate their impact air pollution (AP) underlying mechanisms. The results show that OGD significantly reduces annual average PM 2.5 concentrations by approximately 1.55 units (p < 0.01), indicating notable improvement in quality. Mechanism analysis suggests disclosure affects AP through three pathways: enhancing regulation, stimulating green innovation, optimizing industrial structure. A one-unit increase these mediating variables 0.02, 15.3, 11.75 units, respectively (all p 0.01). In addition, market size openness positively moderate effect OGD. Heterogeneity reveals regional variation. Western China, about 5.61 0.01); Eastern reduction 1.11 0.05), while not significant Central China.

The integration of agriculture, culture, and tourism industries as a driver industrial modernization has become an essential strategy during China’s transition from rapid growth to high-quality development. In pursuit the goal common prosperity, local governments at various levels have actively responded by attempting promote economic through these three industries. Data 126 key national rural revitalization counties in China between 2018 2020 is selected sample, entropy value analysis used, this paper discusses level whether such promoted growth. results show that while seen fluctuating growth, overall remains low with significant disparities across regions. Counties higher development, human capital, digitalization tend However, compared ethnic counties, non-ethnic despite their disadvantage achieved caught up adapting conditions leveraging features. Further indicates even though current not high, it still promotes conclusions provide insights for transitioning poverty alleviation revitalization. By promoting integrated development industries, can achieve narrow regional gaps, ultimately realize prosperity.

Introduction Pollutants from farming and rural life have a serious negative impact on water soil. The advantages of green finance in financial support credit management can guide the transformation agricultural production, thus protecting ecological environment. Methods Based panel data 30 provinces China 2005 to 2021, study used inventory analysis, entropy method two-way fixed effect model analyze non-point source pollution (ANSP) mediating mechanism. Results ANSP has experienced an inverted U-shaped trend first rising then falling, environment is improving. At time level, produced by production evolution increasing decreasing during sample period. spatial significant low regional differentiation. central region coastal economic development area higher than that western region. results linear regression show ANSP. Promoting areas effectively agriculture reduce dependence crop cultivation fertilizers pesticides. This result held even after elimination endogeneity various tests. Land transfer environmental supervision are important intermediary mechanisms. Under influence these two variables, role reduction be fully brought into play. However, there heterogeneity effects ANSPs. Its stronger major grain-producing regions with well-developed digital infrastructure.
