| General Comments: | "SWAT" was one of the high frequency keywords shown in Figure 8. The authors also state that SWAT "has attracted the attention of scholars in 2015 and has been widely used until now. It shows that the SWAT model has been
rapidly developed and widely used, with good simulation effects and practicality." |
| Abstract: | Based on the bibliometric and data visualization analysis software Citespace, this study
carried out document statistics and information mining on theWeb of Science database and characterized
the distributed hydrological model knowledge system from 1986 to 2019. The results show
a few things: (1) from 1986 to 2019, the United States and China accounted for 41% of the total
amount of publications, and they were the main force in the field of distributed hydrological model
research; (2) field research involves multiple disciplines, mainly covering water resources, geology,
earth sciences, environmental sciences, ecology and engineering; (3) the frontier of field research has
shifted from using distributed hydrological models in order to simulate runoff and nonpoint source
environmental responses to the coupling of technologies and products that can obtain high-precision,
high-resolution data with distributed hydrological models. (4) Affected by climate warming, the
melting of glaciers has accelerated, and the spatial distribution of permafrost and water resources
have changed, which has caused a non-negligible impact on the hydrological process. Therefore,
the development of distributed hydrological models suitable for alpine regions and the response of
hydrological processes to climate change have also become important research directions at present. |
