Bibliometrics was used to statistically analyze key zones within the Yangtze River Basin (YRB) funded by the National Natural Science Foundation of China (NSFC) and national ministries over the past 20 years. This study determined that funds that derived from national ministries have mainly focused on issues related to environmental pollution, ecological security, technological water regulations, and river basin ecosystems, which offer a better understanding of the national requirements and the scientific knowledge of the YRB in combination with data from the NSFC. Under a background of bolstering the construction of green ecological corridors in the economic belt of the YRB, this study proposes future conceptual watershed research initiatives in this region as a study objective by reinforcing the implementation of the Chinese Ecosystem Research Network (CERN) and by emphasizing the use of new technologies, new methods, and new concepts for the prospective design of frontier research under the perspective of geoscience and earth system science. This study promotes large-scale scientific field and research objectives based on big science and big data.

Figure 2 Interannual variation in NSFC funding related to hot research topics in the YRB. The color of the bubbles in the figure was only used to distinguish different keywords. |
Figure 3 Time series changes associated with the YRB research topics funded by the MST in 2002-2018 |
Figure 4 Co-occurrence relationship of CNKI keywords in the YRB between 2002 and 2019 |
Figure 5 Timeline visualization of co-citation network in literature associated with YRB. The size of the node represented the cited times of the literature, and the color of the ring represented the cited time. The red citation tree-rings represented that the number of citations in this year is increasing explosively. The appearance of pink ring indicated that the literature has a high betweenness centrality. |
