Abstract: Taking the 186 cultivated land protection policy texts issued by the state from 2005 to 2017 as research samples, the cooperation of policy-making subjects, the change of policy quantity and the configuration of policy tools was analyzed by text quantitative analysis method. The results showed that the main body of cultivated land protection policy issued by the state from 2005 to 2017 remained a diversified feature but lack of synergy. There was an obvious characteristic that the central government dominated the policy-making process. In terms of policy tools allocation, there were some structure defects such as excessive application of environmental policy tools, low frequency of supply policy tools, insufficient application of demand policy tools. It payed too much attention on the functions of "construction" and "characteristic management" of cultivated land, but lacked in the functions of "eating" and "ecological protection". Finally, In view of the deficiencies in the above policy making process, some suggestions for future policy adjustments were put forward.

Key words: policy tools, cultivated land protection policy, text quantitative analysis
