This book presents the Future Land Use Simulation (FLUS) model, a cutting-edge land change modeling framework that seamlessly integrates human activities with natural processes. From theoretical foundations to frontier applications, it enables multi-scale, high-resolution, and dynamic 3D simulation of land systems. Covering critical issues such as urban growth delineation, ecological impact assessment, and global carbon stock forecasting, this volume offers an essential toolkit for researchers and practitioners in geography, urban planning, and environmental science.
