In-depth analysis of uncertainty factors and spatial shifts was made in this study.It combined different geographic data types using digital twin technology and geographic information system (GIS) to create a spatial database for simulating rural water and soil environments.By extensively investigating the affecting aspects, the goal was to improve the accuracy and reliability of rural water and soil environment simulations.The soil and water assessment tool (SWAT) model was explicitly used to characterise changes in soil moisture and hydrological processes.The biological processes of transpiration, photosynthesis, and vegetation development were taken into consideration in the a model for agroforestry systems (AGROFOREST).Climate change was simulated by the autoregressive integrated moving average (ARIMA) model.It was found that various rural activities had obvious effects on the soil erosion rate.In this paper, an accurate simulation of rural soil and water conditions was created by combining GIS and digital twin technology.

The concept of low-carbon and green logistics has pointed out the direction for the development of China's logistics enterprises. This paper analyses the significance and management strategies of China's logistics industry to develop green logistics based on the specific problems in the ecological environment of the current logistics industry development. In addition, constructs a 'three in one' green logistics management strategy from the three dimensions of logistics enterprises, supply chain system and government, that is, from the enterprise's own carbon reduction. In combination with the low carbon requirements for each participant in the construction of the supply chain system, an electronic archive data system for carbon emissions of each logistics enterprise has been set up to form a bottom-up, inside out green logistics construction system strategy, providing reference for the specific implementation strategy of green logistics development.

The concept of smart city (SC) is an extensive approach to the functioning of urban centres and among the most important issues associated with SC's applications is urban waste management, which negatively impacts society's environment and health if not properly managed. This article proposes to identify the worldwide trends in solid waste collection and transportation in SC and the main challenges in future research. Hence, a review was performed using Methodi InOrdinatio and bibliometrix R-tool, applied to two merged databases, to review a selected portfolio and contribute to direct future research. Results show that environmental and economic dimensions appeared more frequently in the articles (94.3%) and that social analysis is scarce when dealing with waste management, since only 10% of articles addressed social aspects. The social contexts of sustainable development are important factors to be considered due to the many informal and associated waste pickers working with waste collection and separation in low and middle-income countries.

This paper studies the external wall energy conservation construction technology of campus buildings under the premise of considering the energy consumption quota limitation. Firstly, it analyses the exterior wall structure system of campus buildings, analyses the influencing factors of structure system selection, and calculates the ultra-low energy consumption of campus buildings; Secondly, the steady-state calculation method is used to estimate the internal surface temperature at the corner of the external wall of the school building, and the energy-saving structure of the external wall of the school building is realised by considering the restriction. According to the wall design requirements of campus building exterior wall, the corresponding evaluation indexes are determined, and the reasonable evaluation results of campus building exterior wall energy conservation are selected. The energy-saving performance of the proposed method is verified by the condensation in summer and the accuracy of energy-saving control of campus building exterior wall.
