Heilongjiang province is an important base for marketable grain production in China, whose total area of cultivated land, per capita cultivated area, and output of foodstuffs are all in the first place. The state of cultivated land resources of Heilongjiang province influences the security of national cultivated land resources and food security directly. This paper took Heilongjiang, the biggest base for marketable grain production in our country, as research region, from the aspects of cultivated land own security, economic security, social security and ecological security and combined with practical situation of Heilongjiang cultivated land resources, to establish evaluation index system and use method of analytic and evaluation hierarchy process to analyze the operation status of the security of cultivated land resources in Heilongjiang from 1998-2007.The results showed that the security state of cultivated land in Heilongjiang was different from period to period, the stage of the continued to deteriorate from 1998 to 2001, the state of fluctuation changed from 2002 to 2007 and the overall state is at a relatively security situation. Only the evaluation value of 2001 entered into the ranks of insecurity and the rest are in a relatively safe range, the social function and ecological function of land resources are basically the same as the trend of comprehensive evaluation.
