Abstract:: Based on the annual survey data of land use changes in Qinghai, we analyzed the change characteristics of cultivated land quantity by taking the situation of cultivated land increase or decrease and cultivated land used for construction into consideration. And in terms of the regional differences in cultivated land changes and the difference of cultivated land increases, we also analyzed the regional features of cultivated land changes in Qinghai. On the basis of these analyses, we put forward different management strategies. The results showed that: (1) cultivated land resources mainly concentrate in Xining city and Haidong district, land management and consolidation were the major source of new cultivated land, while ecological restoration and construction were the major forces driving cultivated land loss; (2) farmland occupation was usually delayed after getting approval, which had a big impact on farmland occupation plan in the year; (3) in order to protect farmland in Qinghai, we should stick to the most stringent farmland protection laws and should carry out the differentiated land use policies.
