The results show that: in the 20 years, under the guidance of national policies, the number and amount of cultivated land use management projects are increasing; the types of projects are mainly youth science fund projects, general projects and regional science fund projects; the youth scientific research team is growing, and the scope of project approval units is wide, but most of the projects are concentrated in institutions with strong research strength; the project departments and research directions tend to be diversified. While deeply exploring the traditional mainstream directions, the funding expands the research theme, innovates the research ideas and grasps the new hot spot of the research. According to the analysis, the research content of the fund project is becoming more abundant and the research system is gradually systematic, but the depth and real-time of the research should be strengthened, the protection, the sustainable utilization and the evaluation of cultivated land are the hot spots in recent years, and the related research needs to be improved.
