Abstract: Revealing the spatial pattern and influencing factors of cultivated land fragmentation in typical counties in the northeast black soil region can provide a basis for high-standard farmland construction, three-round land contracting and black land protection in the black soil region. Taking Baiquan County as the research area, this paper calculated the weight of each index and the comprehensive evaluation value of cultivated land fragmentation by the entropy method, and examined the effect intensity of each influencing factor by the Pearson correlation coefficient analysis method. Results showed that: 1) the cultivated land fragmentation was deeply affected by the topography. The cultivated land fragmentation level was the highest in the border area of hills and plain, followed by hilly area and plain area. Cultivated land ownership fragmentation was affected by land subcontracting and the average cultivated land area per household; 2) in the cultivated land fragmentation mode, "low degree of landscape fragmentation-low degree of ownership fragmentation" and "low degree of landscape fragmentation-medium degree of ownership fragmentation" were dominant, accounting for 33.33% and 17.20%, respectively; and 3) the main influencing factors of cultivated land fragmentation included ownership, facility, and natural cutting forces. Ownership cutting force showed a high negative correlation, while facility and natural cutting forces showed moderate positive correlations, with correlation coefficients of -0.775, 0.617 and 0.661, respectively. Ownership cutting force had the greatest influence. The spatial differentiation of cultivated land fragmentation in Baiquan County was obvious. Therefore, this paper suggests exploring countermeasures of cultivated land fragmentation in the northeast black soil area from the dual perspectives of landscape and ownership to provide reference for promoting agricultural modernization and formulating the third round of cultivated land contracting policy.
