Research Progress, Hotspots and Trends of Land Use under the Background of Ecological Civilization in China: Visual Analysis Based on the CNKI Database

Land use is a fundamental element of ecological civilization, whose relevant academic results are not only a concentrated expression of the construction of ecological civilization and land use but also an important theoretical basis for guiding land use changes to promote the construction of ecological civilization. Therefore, based on CiteSpace visual software, this paper analyzes the research progress, hotspots, and trends of 558 articles related to land use under the background of ecological civilization in China based on the China National Knowledge Infrastructure (CNKI) database. The results are as follows: (1) The research cycle is characterized by two distinct stages: the nascent stage and the fluctuating growth stage. (2) The number of publications by researchers and institutions is low, the collaborative network is fragmented, and a core of research researchers and institutions has not yet been formed. (3) The journals in which the papers are published indicate that the research is cross-disciplinary in character, while the highly cited journals have a central role, and the research content of the high-frequency cited papers mainly includes three parts: spatiotemporal evolution pattern and measurement, spatial planning, and land reclamation. (4) The research hotspots are grouped into 12 keyword clusters, which can be further grouped into two sections: "ecological civilization construction and land use" and "national spatial planning". (5) The burst of territorial spatial planning has reached 2022 and will continue to be a research hotspot in this field in the future. The results of this study can help relevant scholars clarify the research context and current situation in this field and grasp future research directions.
