Abstract: In order to summarize the research status of mammal species diversity and geographical distribution in China's provinces （autonomous regions and municipalities directly under the central government） based on infrared camera technology, and to clarify the research blank or less research areas, so as to provide a basis for formulating relative protection, monitoring and management plans. Using the literature retrieval method, the relevant literature of wildlife diversity investigation and research in Chinese territory based on infrared camera by scholars from various countries was systematically collected and sorted out. The results showed that at least 208 wild mammal species were recorded by infrared cameras in China, belonging to 11 orders and 37 families, accounting for 30.06% of the total mammal species in China. At present, the mammal species diversity monitoring research by infrared camera in China has basically covered the whole country. Among the 34 provinces （autonomous regions and municipalities directly under the central government）, 32 provinces （autonomous regions and municipalities directly under the central government） have recorded animal species investigation based on infrared cameras, but most of them are concentrated in the southwest and northeast regions. According to the number of research sites, the number of documents and the proportion of mammal species recorded by infrared camera in the total number of species in each province （autonomous regions and municipalities directly under the central government）, Chongqing, Liaoning, Jiangsu, Fujian, Inner Mongolia, Taiwan and Shanghai have potential investigation values. There is still some room for improvement of mammal species diversity monitoring based on infrared camera technology in China, and more systematic and in-depth monitoring research is needed.
