Bibliometric Analysis of Black Soil Protection from the Perspective of Land-Use Monitoring

Land use affects ecosystem stability and agricultural ecological security in black soil regions. Additional attention is required regarding the impact of different land-use patterns on soil. However, construction sustainable environments a dynamic process that depends reviews experts statistical analyses literature data. This study quantitatively reviewed past 20 years Using superposition expert knowledge map machine clustering, land fields was classified structurally. Further, studies directly related to spatiotemporal pattern were identified, frequently cited works screened build network research. The results show (1) cooperative relationship among China, United States, Canada strongest, but density cooperation networks between other countries low; (2) research divided into four areas: microbial community activity, erosion processes, management use, organic matter, element cycling; (3) monitoring mode areas should be established include information incorporates cultivated factor potential, grain production capacity assessment, evaluation prediction, farmland landscape planning.
