Abstract: With subtropical monsoon climate, abundant mountain resources, and diverse soil conditions, the southeastern hilly areas in China are ideal for the growth of tea plants and indeed pivotal for the agriculture development in the nation. President Xi Jinping viewed forests as a grand repository of water, food, wealth, and carbon resources, which he descriptively named it “Four Reservoirs.” Truly, the vision can fittingly be applied to ecological tea farming in hilly regions. To extrapolate the concept for practice, this article formulated a theoretical framework and utilized the past experiences of the industry at Anxi, Wuyishan, and Pinghe in Fujian Province to explore plausible venues in building a “tea forest” that is operated under the green and ecological principles of symbiosis, vertical planting, soil improvement, green pest control, and diversified management. The system development would synergistically achieve the goals of water conservation, providence of eco-friendly products, sustainable economic growth, and needed carbon sequestration, materially making four “reservoirs” out of the lands. Meanwhile, by following the “Three Tea Integration” principle for the industrial development, this study aims to achieve simultaneously the green and ecological idealism, industrial development, and technical advances on water retention and carbon sequestration. In the end, the “invaluable assets of lucid waters and lush mountains” could be realized. Moreover, the implicit tea culture teaching would unite spirits of visitors, the evolving tea sci-tech would usher in innovation and advancements, and the flourishing tea industry would foster social and economic progress in the regions. With the theoretic framework and pathway proposed in this article, hopefully, a transformation from a singularly purposed economic operation to a multifunctional service provider of the tea industry would become a reality, as the southeastern hilly regions turn from wilderness to ever-productive lands of the future.
