| Abstract: |
| Purpose The fragmentation of farmland has always been a significant challenge hindering the modernization of agriculture in China. “Merging small fields into large fields”is an important achievement in the construction of high-standard farmland and land consolidation in our country. It is of great significance to clarify the current research status and identify the hotspots of“merging small fields into large fields”in China.Method This study conducted a nationwide analysis of these hotspots based on 153 research reports retrieved from the China National Knowledge Infrastructure（CNKI）database and the mainstream media "CCTV News". Using Excel，the study analyzed the types of research reports，annual publication volume，regions where the transformation from small to large fields was being implemented，and the number of publications in different regions. The study also used the natural breaks method in ArcGIS software to categorize the regions of the transformation from small to large fields into four levels：high-heat areas，medium-heat areas，low-heat areas，and cold spots.Result （1）"Merging small fields into large fields" had received increasing attention. The earliest research report with "merging small fields into large fields" as the theme appeared in 2008，and since 2021，"merging small fields into large fields" had received significant attention. （2）There were obvious regional differences in the implementation of "merging small fields into large fields". Among them，Anhui had the most research reports on this topic，with a total of 52 reports，accounting for 38. 52%. Jiangsu ranked second with 18 reports，accounting for 13.33%. （3）There were differences in the reporting angles among different subjects implementing "merging small fields into large fields". The government departments focused on implementation methods，while the mainstream media focused on implementation effects，and the researchers focused on scientific issues in the implementation process.Conclusion "Merging small fields into large fields" is currently a new direction and goal of rural land reform in China. The attention of domestic researchers to "merging small fields into large fields" is increasing，and future research on"merging small fields into large fields" change detection can be further conducted. |
