Beautiful China Initiative (BCI) aims at sustainable development with blue sky and green land, lucid waters and lush mountains, prosperous society and rich people, and harmony between humans and nature. The BCI is a Chinese practice to implement the SDGs 2030 of the United Nations, and an important method to promote the harmonious development between humans and nature and to win the gold and silver mountains by maintaining clear waters and green mountains. Geography, an applied cross-discipline serving the country's socio-economic development, has comprehensive and regional characteristics. Geographers shoulder the historical mission of building a beautiful China, and are duty-bound to take the lead in becoming pioneers and practitioners of the BCI. The theory of pericoupling and telecoupling between humans and nature is the theoretical foundation of the BCI. The interdisciplinary and comprehensive integration of geography is the practical means for the BCI. The complex system simulation and optimization of geography provide a scientific tool for coupling ways between humans and nature of the BCI. The main coupling ways for geography to promote the BCI include: carry out major scientific and technological projects and coupling demonstrations; perform dynamic assessment and monitoring of the coupled human and natural systems for the BCI; draw up the strategic coupling roadmap and the action plan of the 14th Five-Year Plan (2021-2025) for the BCI; build a concept of beautiful land to comply with the objectives of the National Territorial Space Plan of China; develop a comprehensive regionalization of coupled human and natural systems in accordance with local conditions, and build a group of beautiful urban agglomerations and national parks; undertake pilot projects for the construction of Beautiful China and summarize the regional coupling models for the BCI. These coupling paths will ensure that the whole country and each of its provincial-level region are getting closer to the target according to the schedule and roadmap for building a beautiful China, and diverse regions will achieve the overall goals in the competition.
