The human-earth system (HES) is a complex adaptive system that embodies the interconnection and interaction between human activities and the geographical environment, characterized by a variety of features such as comprehensiveness, regionality, complexity, openness, and dynamics. Socio-economic development is facing increasingly serious regional problems such as land degradation, environmental pollution, and biodiversity loss. In essence, it is the result of the intensified impact of human activities on the earth system, resulting in the coupling disorder and functional imbalance of HES. Therefore, the spatial identification, type diagnosis, and intensity evaluation of HES are critical topics in modern HES science and comprehensive geography. These themes form the foundation for scientifically cognizing the evolution process and mechanisms of HES, as well as for supporting decision-making aimed at HES coordination and sustainable development. Based on the theory of human-earth relationship areal system and the geographic methodology of “main function-oriented zoning, dominant type classification, and principal purpose grading”, this study constructed a top-down scientific cognition and method system for modern HES identification-diagnosis-evaluation. The study integrated multi-source spatial data of land use, population density, nighttime light index, and point of interest, adopted multiple quantitative methods of decision tree, spatial clustering, and human footprint intens...
