Abstract: In order to reveal the research progress and key points of SCS hydrology model in watershed research in China，and provide a reference for the future research，284 journal papers and 168 master and doctor papers in this field from 2000 to 2019were sort out． Citespace5． 7 Ｒ1 software and CNKI visual analysis module were used to conduct bibliometric statistical analysis on the paper volume，keywords，authors and research institutions in this field． The results show that the total amount of scientific research papers in the field of SCS hydrology model research is increasing． The research focuses on two aspects: on one hand，the coupling application research of SCS hydrology model and other models can provide theoretical support for flood disaster early warning and response; on the other hand，remote sensing technology is used to calibrate the CN value at small － scale basin，so as to establish the CN value database suitable for various regions in China，providing a foundation for runoff simulation in medium and large scale basin． Ｒesearch team has developed decentralized and diversified over time，including the team of Professor LIANG Zhongmin of Hohai University，Professor SONG Xiaoyu of Xi'an University of Technology，Professor LIANG Juping of Northwest A ＆ F University，Professor SHI Peijun of Beijing Normal University and Academician LIU Changming of University of Chinese Academy of Sciences，which were core research teams at different stages of development and have made important contributions to the development of SCS hydrology model． It can be seen that in the case of frequent heavy rain and flood disasters in China，theSCS model will be a hot research topic to simulate runoff in small，medium and large scale basins in the future．
