Against the background of the French "May Wave" and the postmodernist, the theory of assemblage as a research perspective starts to gain momentum. This paper proposes a philosophical view of "becoming" based on rhizome thinking, which critically exposes ignorance of the spatial topology in the current research based on network structure and opens up a new field of the knowledge for human geography. On the one hand, the assemblage theory forms a "heterogeneous generated space" on the basis of spatial theories such as "spatial production theory", "heterotopia" and "third space", emphasizing the interactions of the heterogeneous elements while also paying attention to the logic of the continuous generation and spatio-temporal change; on the other hand, the assemblage theory reconstructs the concept of relations, emphasizes the "object agency" and "relations of exteriority", which generates the "post-relational ontology" and acknowledges that all things are assembled through relations. With the application of the assemblage theory in the field of human geography, the existing empirical research mainly focuses on political assemblage and mobility, urban assemblage and critical urbanism, daily life assemblage and non-human agency, and compared with other related theories such as Complexity Theory and Actor Network Theory. In order to expound the connotation of the assemblage theory and enhance the applicability of the theory, the article analyzes the assemblage logic through border assemblage. In addition, based on the new research framework and theoretical paradigm constructed by the assemblage theory for human geography, as well as the coupling of the theoretical characteristics and the transitional period of Chinese society, it is expected that Chinese geographers can critically engage into the assemblage theory to explain the Chinese situation, as well as promoting the diversities of the Chinese geography theory and philosophical methodology.

Socioeconomic statistical data is usually aggregated in units of administrative regions. The socioeconomic statistical data can reflect the heterogeneity between statistical units, but it cannot reflect the heterogeneity within a statistical unit. The socioeconomic statistical data cannot meet the needs of socioeconomic departments concerned in arbitrary regions. The spatial disaggregation of socioeconomic statistical data is an effective way to solve this problem. This study summarizes the existing methods of spatial disaggregation of socioeconomic statistical data, the auxiliary data used in methods for obtaining spatial disaggregation of socioeconomic statistical data, and the main socioeconomic grid data products. This study also predicts future development trends of the spatial disaggregation of socioeconomic statistical data in three aspects: the constraints and improvement directions of methods, the exploration of new auxiliary data and the comprehensive utilization of multi-source auxiliary data, the development of high temporal and spatial resolution and high-precision grid data products. The research results can provide references for the selection and improvement of spatial disaggregation methods of socioeconomic statistical data, the selection and comprehensive utilization of auxiliary data, and the selection and improvement of socioeconomic grid data products.

Based on materials mainly comprising name lists, biographies, short introductions, dictionaries of/on geographers, historical records overviewing colleges and universities, histories of geography departments, and so on, this study aims at revealing the development process of geographers in China in the period 1912-1949 from a ternary perspective of source, growth, and structure. The key data on geographers' birth and death years, native places, subdisciplines or fields they contributed to, and their educational and working backgrounds are extracted and used to identify geographers and evaluate their development process. A total of 460 geographers (449 Chinese, 11 foreigners) are identified. The research reveals the following: First, geographers can be categorized into three types: traditional, foreign, and scientific cultivation (including domestic trained, overseas trained, and interdisciplinary scholars), and the changes in geographer type reflected the change of disciplinary traditions. Second, the development of geographers can be divided into four periods: initial growth (1912-1927), continuous growth (1928-1939), rapid growth (1940-1941), and slow growth (1942-1949). Third, the distribution of Chinese geographers' subdisciplines or fields, research directions, native places, ages, and gender showed a pattern of obvious unbalance but continuous optimization. Finally, the development of geographers was closely related to the establishment of teaching and scientific research institutions. The higher teaching institutions had a "double-track" effect (employing and training) on the development of geographers in terms of recruitment and training. In particular, the contribution of university geography departments to the cultivation of geographers was characterized as the "double-track" system related to the types of universities and departments. Geoscience departments in comprehensive universities and those jointly established with geology and meteorology departments made outstanding contributions to the development of geography, while geoscience departments in universities tended to train physical geographers. Overall, the number of geographers in China, particularly Chinese geographers, and the rate at which that number increased were considerable, albeit unevenly distributed over time. Notably, the development of Chinese geographers from 1912 to 1949 laid a solid talent foundation for the further development of Chinese geography after 1949. The progress of the development of Chinese geographers from 1912 to 1949 was also remarkable, and was the result of the efforts of senior, outstanding, famous, young, and female geographers, and the participation of foreign companions.
