The optimal control of the human-earth system plays the most important role in the theoretical foundation of human-earth areal system (abbreviated as the "human-earth system") advocated by Academician Wu Chuanjun. Based on the thinking and related discussion of optimal control of human-earth system proposed by Academician Wu, this paper deepened and expanded the theoretical and methodological aspects of structure, nonlinear effects, coupling relationship and evolution of the human-earth system. After that, we focused on the following two aspects. The first is to discuss the optimization of human-earth system and coordinated development of regional PRED (i.e., population, resources, environment, and development), including the relationship between human-earth system optimization and PRED coordinated development, as well as the objectives, key points, theoretical models and quantitative measures of coordinated development of PRED. The second is to explore the path and countermeasures of comprehensive regulation of human-earth system in the new era. First of all, we should promote the continuous and healthy development of human-earth systems through innovation. Secondly, we should optimize the spatial pattern of the human-earth system according to the main function-oriented zoning. Thirdly, we should build a modern economic system through supply-side structural reforms. Fourthly, setting long-term balanced development of population as a goal, we should gradually improve the population policy. Finally, we should follow the market principles to improve the mechanism of paid use of resources and environment and ecological compensation.

Key words: human-earth system (human-earth areal system), optimization, coordinated development of regional PRED, comprehensive regulation, theories and methods
