With the progress of holistic science and human society, development of geographical sciences has entered a new stage of interdisciplinary integration. Under this context, geographical sciences urgently needs to seek new paths through the deep integration of disciplines to better improve the knowledge system and contribute to the country and society development effectively. Based on the perspective of the National Natural Science Foundation of China (NSFC), this paper firstly deeply analyzes the current status and problems of the integration and development of geographical sciences in China, and points out that it is not fully integrated with the frontier of international geographical sciences, and the global political, economic and cultural influence of geographical research in China needs to be strengthened; considers that the ability of Geographic Sciences integrating national major practical needs for theoretical and technological innovation should be improved; suggests that the internal discipline system of geographical sciences in China should be further optimized according to the needs of knowledge integration. Then, this paper proposes three paths for the integrated development of geographical sciences under the guidance of funding policies, that is, the interdisciplinary integration facing the frontiers of science and technology in the world, the multiple fields integration facing the major national development strategies, and inner-discipline integration facing the optimized application codes of NSFC. In future, based on maintaining the continuity and stability of the development of disciplines, the NSFC will encourage the integration of geographical sciences with other disciplines and fields through the improvement and innovation, so as to promote and build a healthier and more innovative system.

The interaction between health and environment is the most essential man-land relationship. Geography plays a significant role in the construction of Healthy China. It can provide path guidance based on development strategy, process evaluation and policy orientation, theoretical guidance based on man-land relationship harmony and spatial system optimization, and practical guidance based on healthy life, health service, health environment, health security and health industry layout. Combining the disciplinary characteristics of geography and the five key areas of the construction of Healthy China, geography could play a unique part in the 18 aspects, including sub-disciplines of health geography, tourism geography, economic geography, urban geography, behavioral geography, population geography, information geography, social geography, cultural geography, rural geography, and environmental geography. First, it promotes healthy life in areas of regional residents' health literacy, living style, and spatio-temporal behavior, as well as regional population mental health. Secondly, it improves healthy service in areas of disadvantaged people health service, major diseases prevention and control, and sustainable health in key regions. Thirdly, it constructs an environment in areas of healthy eco-environmental construction, healthy climate change response, environmental health risk detection, healthy urban and rural environmental construction, and healthy cultural landscape construction. Next, it enhances healthy protection in areas of geographic information system (GIS), optimization of medical resource allocation, healthy services accessibility, and fairness. Finally, it develops healthy industry in areas of development of local medicine and traditional Chinese medical industry, healthy tourism and entertainment, optimization of senior care, maternal and infant industry. However, nowadays, the contribution of geography in building the Healthy China is limited because of the following reasons: (1) weak basis for health geography; (2) lack of strong sense of participation; and (3) lack of policy support from geographical organization. In the future, more research should be focused on problem-oriented and policy-oriented geographical theory, empirical and policy research, health promotion research of deep integration of geographic technology and thinking, and systematic guidance and policy support for geographers to participate in the construction of Healthy China.
