Abstract: Since the third national land survey, although the area of agricultural land has increased, the number of cultivated land has decreased compared with the second adjustment period． The state proposes to implement hard measures of ＂long teeth＂ for cultivated land protection, strictly abide by the red line of 120 million hm² of cultivated land, and prevent non-agricultural and non grain transformation of cultivated land． Two county-level databases were selected to analyze planting attributes and restoration attributes of database from perspective of investigation, and a conclusion was obtained that there were large differences in cultivated land planting between plain areas and mountainous areas and different directions of cultivated land circulation due to location reasons． Finally, three countermeasures for cultivated land protection were put forward．
