The establishment of the National Social Science Fund (National Social Science Fund) project is not only an important symbol of the scientific research strength and organizational ability of each region, but also reflects the development trend and hot direction of the discipline field. Existing bibliometrics studies focus more on bibliometrics analysis, and less on the perspective of national social science projects. Using the National Social Science Foundation project database as the data source, this paper collected and analyzed the projects whose provinces, regions, and cities were in Guangdong Province from 1994-2021 for statistical analysis, and used methods such as bibliometrics and knowledge map to describe the knowledge picture of social science research in Guangdong Province reflected in the national social science project in Guangdong Province. The results showed as follows: (1) During the study period, a total of 4 794 national social science projects were established in Guangdong Province, ranking fourth among all provinces, regions, and municipalities (excluding Hong Kong, Macao, and Taiwan), with an average annual growth rate of 15.7%. Among them, there were 3 211 general projects, youth projects and later funded projects, and 444 major projects and key projects, all of which were higher than the national average. (2) The project disciplines mainly focus on the applied economy, Chinese literature, linguistics, and sociology, with keywords such as "carbon emission", "leisure agriculture", "tropical climate", "rural tourism" and "rural revitalization" as the research themes. The research results are mainly monographs, papers, reports, and these combined, large-scale surveys, computer software, and reference books are lacking. (3) The project approval units are mainly institutions of higher learning, among which, Sun Yat-sen University, Jinan University, and South China Normal University have a large number of projects, while Guangzhou University and Guangdong University of Foreign Studies have made significant progress in recent years. (4) The number of projects initiated by the core hosts reached 57%, but the number only accounted for one-tenth of the total number of project leaders. The discipline of the core host is sociology. Overall, the number of national social science projects in Guangdong Province has increased steadily, and the projects are mainly concentrated in a few key universities, superior disciplines and core hosts. In the future, based on maintaining superior disciplines, Guangdong Province should focus on expanding non-superior disciplines, cultivating competitive scientific research institutions, building scientific and reasonable research echelons including senior, middle-aged, and young scientists, forming a situation that includes a wide variety of subject area, and further strengthening the strength of social science research in Guangdong Province.

Under the background of Chinese culture goes global, the study of Guangdong Province, one of the important economic regions in China, has become one of the most important contents for the construction of Guangdong's overseas image and Sino-Japanese cultural mutual understanding by Japanese academics. In this paper, we take the research topics on Guangdong included in the Database of Grants-in-Aid for Scientific Research(KAKEN) as the data source, and use CiteSpace to visualize and analyze the academic groups, research institutes, and core contents, in order to present the focuses and trends of the research on Guangdong Province in the Japanese academia. The results show that the research on Guangdong Province in Japanese academia involves a large number of research groups and research institutions, and the research hotspots show the characteristics of "economy-country-region" over time, mainly focusing on the Chinese diaspora in the East Asian region, the culture of Chinese clans, and the industrial economy of Guangdong, focusing on regional countries, economic development, and the development of Guangdong. The research focuses on the three core clusters of regional countries, economic development and language and culture. By systematically organizing and evaluating the academic achievements of Guangdong studies in the Japanese academic community, we can provide a "knowledge map of Guangdong studies in the Japanese academic community" with certain reference value for future research and policy making on the dissemination of Guangdong's culture overseas and image writing.

"Scholars" provide a core perspective to study academic history. Through scholars' lineage relationships, we can describe the formation of disciplines, the evolution of academic schools, the inheritance of academic thoughts, and even the internal factional disputes within the discipline. However, discussions on intellectual lineage relationships and their impacts have been overlooked in the study of the history of geographical thought. This paper takes the lineage relationships of prominent human geography scholars in the Chinese Republican era as an example. Based on the lineage relationships of representative scholars, it analyzes the formation and development of modern Chinese human geography as a discipline, explores the influence of lineage networks on the formation and inheritance of academic schools and the integration of Western and Chinese geographical thoughts, and discusses the political issues within the discipline triggered by lineage relationships. Finally, this paper systematically discusses the inspiration of the perspective of lineage relationships on the study of the history of geographical thought.
