Abstract: Transboundary conservation has profound significance for the biodiversity conservation in the boundary, and is becoming a
hot topic in the development and study of reserve network. In recent years, studies on transboundary conservation in foreign are
becoming more and more mature, and the studies in China have also been improved. However, the concepts of different transboundary
types have been confused, and studies on trans-region cooperative conservation within the country is often ignored. First of all, this
study defines the concept of different transboundary cooperative conservation. Bibliometric analysis is used to analyze the trend of
transboundary study on environment or resources, and then statistical analysis is conducted on the numbers of trans-region reserves
and mutual-adjacent district boundary reserves in China. The results show that the study and cooperation of trans-region conservation
are rare in China, but trans-region reserves and mutual-adjacent district boundary reserves are common, and the demand for the
cooperation of trans-region conservation is strong. Finally, this study puts forward proposals on the study and cooperation of transregion
conservation in response to establish natural reserve system with national park as the main body, and is committed to meet the
needs of ecological civilization construction and sustainable development strategy in China.
