It is of great practical significance for protecting cultivated land and guaranteeing national food security to thoroughly explore the spatio-temporal variation characteristics and driving factors of cultivated land. Based on the land use data of Heilongjiang Province in 1980, 1990, 2000, 2010 and 2015, this article determined the spatiotemporal differentiation characteristics and main driving factors of cultivated land change in Heilongjiang Province in the four periods from 1980 to 2015 by using GIS and geographical detector model. The results show that from 1980 to 2015, the cultivated land quantity in Heilongjiang Province increased, and the increased cultivated land mainly came from forest land, grassland and unused land. The variation of cultivated land quantity in each period was obviously different, with the largest variation from 1990 to 2000. The spatial difference of cultivated land change in each period was obvious. From 1980 to 2015, the dynamic degree of cultivated land use in Heilongjiang Province showed a trend of increasing first and then decreasing, and the regions with active dynamic degree of cultivated land use were concentrated in the Sanjiang Plain and the Songnen Plain. The explanatory ability of drivers factors are different in each period. Population size, policy factors, GDP and urbanization level are the driving factors with strong explanatory ability. The influence of driving factors on the spatiotemporal change of cultivated land is realized through the interaction of various factors, which is manifested as double factor enhancement and nonlinear enhancement.

Key words: cultivated land, land use, temporal and spatial variation, driving force, Heilongjiang Province
