The North China Plain is a crucial agricultural region in China, but irregular precipitation patterns have led to significant water shortages. To address this, analyzing the high-resolution dynamics of root-zone soil moisture transport essential for optimizing irrigation strategies and improving resource efficiency. Richards equation robust model describing across multiple layers, yet its application at large spatial scales hindered by sensitivity boundary conditions parameters. This study...

Cities are growing higher and denser, understanding constructing the compact city form is of great importance to optimize sustainable urbanization. The two-dimensional (2D) urban has been widely studied by previous researchers, while driving mechanism three-dimensional (3D) morphology, which reflects reality environment seldom developed. In this study, land surface temperature (LST) was retrieved using mono-window algorithm method based on Landsat 8 images Xiamen in South China, were...

Climate change and urbanization have led to an increase in extreme weather urban heat islands. Green space can help regulate the thermal environment, but previous studies focused on two-dimensional (2D) indicators, neglecting intrinsic three-dimensional (3D) characteristics of green space. Therefore, we developed a set 3D landscape indices define configurations, including characteristic, shape, compactness, based ecology law universal gravity, quantify its benefits for environment. We...

The rapid rate of urbanization is causing increasing annual urban energy usage, drastic shortages, and pollution. Building operational consumption carbon emissions (BECCE) account for a substantial proportion greenhouse gas emissions, crucially influencing global warming the sustainability socioeconomic development. As foundation building conservation, determination refined statistics BECCE attracting attention. However, reliable accurate representation remains lacking. This study proposed...

Building sector consists of a major part global energy consumption and carbon emission. Reducing in buildings can make substantial contribution towards the strategic goal neutrality. emission (BECCE) is highly correlated with microclimate. Green space has long been recognized as natural way to improve microclimate reduce BECCE. However, effective distance optimized configuration green for reduction BECCE are hardly known. To this purpose, we developed compactness (GSC) index an indicator...

Urban sprawl has led to various economic, social, and environmental problems. Therefore, it is very significant improve the efficiency of resource usage promote development compact urban form. It a common topic that measuring compactness done with certain ways methods as well. Presently, most measurement are based on two-dimensional (2D) formats, but three-dimensional (3D) formats can precisely describe actual spatial conditions still lacking. To measure 3D form accurately, Compactness Index...

Habitat selection has been a central focus of animal ecology, with research primarily concentrating on habitat choice, utilization, and evaluation. However, studies confined to single scale often fail reveal the needs animals fully accurately. This paper investigates wintering whooper swan (Cygnus cygnus) in Manas National Wetland Park, Xinjiang, using satellite tracking determine their locations. The Maximum Entropy model (MaxEnt) was applied explore multi-scales Park’s swans across...

Based on the resource-based cities, we could establish a comprehensive evaluation index system. Principal component analysis (PCA) model is perfect to such evaluation. It can eliminate related influence between indexes and reduce workload of The paper applied principal Baotou city other 5 western cities so as make about sustainable development ability. results show that ability from2003 2012 fluctuated improving trend. And it ranks fourth in selected cities. issue way improve discussed this paper.
