Compared with the increasingly obvious humanistic tendency in foreign human geography, China's human and economic geography still follows Academician Wu Chuanjun's theory, with human and economic geography as an interdisciplinary subject which is the study of the formation and evolution of the distribution pattern of human activities under the interaction of natural circle and human circle. And China's mainstream school on human and economic geography has been formed with studies on spatio-temporal rule of sustainable development on territories with different space scales, territories with important production and living, and territories with typical geospatial patterns as the main research points. "Territorial System of Human-environment Interaction", developed by Academician Wu Chuanjun, is the important theoretical foundation not only for human and economic geography, but also for the comprehensive research on geography. The essence of the theory, which includes territorial functional, system structured, orderly process for spatio-temporal variation, and the difference and controllability of human-environment interaction system effect, is entirely harmonious with the forefront of thought of the "Future Earth" studies program. In recent decade, with scientific mode of urbanization, major function oriented zoning, road map for the Belt and Road Initiative, Beijing-Tianjin-Hebei urban agglomeration, rural hollowing and targeted poverty alleviation, revitalization of Northeast China and transformation of resource-based cities, and administrative area optimization as the main research objects, theoretical methods have been developed in the aspects of important sustainable process of human and economic geography, territorial function formation and ordering rules for comprehensive geographical pattern, formation and evolution mechanism of urban agglomeration and its resources and environmental effects, sustainable life cycle and the revitalization of the path for problem areas, the interaction between geopolitics, geo-economy and regions, and effect of cultural boundaries on sustainable development. China's human and economic geography has made great progress in discipline development, and the application results have produced profound influences on the ecological civilization construction and sustainable development in recent years. With decades of hard work, China's human and economic geography has reached a world-class advanced level, so as to console the soul and spirit of Wu Chuanjun on the occasion of commemoration of the centenary of his birth.
