Abstract: The use of visualized bibliometrics analysis helps the evaluation on the advancement of the researches on rural industry suitability under ecological constraints objectively, which promotes knowledge about frontiers of the researches at home and abroad, thus pushing the research fast forwards in China. With the aid of the CiteSpace software. the bibliometric analysis of the data cited from the Web of Science and China National Knowledge Infrastructure (CNKI) was performed to review the researches on rural industry suitability under ecological constraints both at home and abroad from 1992 to 2020. The relevant international researches for this direction has been pioneering researches on resource carrying capacity and industrial suitability under ecological constraints such as climate change, land use, water resources management, and industrial suitability driven by the economy. From 2011 to 2020, researches have been focused more on how climate change affects industrial suitability and the transition from ecological resources to asset management techniques instead of limited to the ecological constraints associated with resource carrying capacity. In China, the research direction in this field is affected by policy initiatives and pioneering foreign researches. From 1992 to 2010, the researches were focused more on optimizing and adjusting the rural industrial structure and constructing an ecological safety system, based on Wooden Barrel Theory, by accurately quantifying the elasticity of different ecological resources, defining the limit condition of specific industries that do not damage the restoration capacity of ecosystem. In recent ten years, as the ecological effect of industrial development constraints has become significant, the concept of "ecological constraint" has been formally accepted, and the focus of researches is no longer limited to "ecological suitability" one-way analysis. At present, "clarity and measurement, coordination and capitalization, policy and the bottom line" have become the focus of ecological constraints related to the development of rural industries. It is important to develop the industry as quickly as possible without sacrificing the resilience of the ecosystem. Finally, the contents, methods, and research results on the suitability of rural industries under the constraints of ecological security in the past 30 years are analyzed, and the insufficiency of relevant research in China and the future development directions are proposed.
