Peasant is the "practitioner" of ecology governance policy, and also the "inspector" of policy execution effect, whose satisfaction is essential to the sustainability of the policy implementation. In total, 1417 peasants were investigated around the perimeter of desertification land enclosed and desertification land sealed protection area of 14 pilot cities and counties in Gansu Province. Using Pareto analysis method and Ordered Logit model, this article analyzed the peasants' satisfaction and its influence factors of the national protection policy in the enclosed and forbidden reserves of desertification land. The analysis on externally influential factors indicated that peasant satisfaction with the national enclosed and forbidden reserves of desertification land protection policy was between "being ordinary" and "being satisfied" with average value of 3.67 (great satisfaction value with 5). There were positive correlations between aeolian sandy soil hazard alleviation degree, conversion level of desertification, improvement condition of family income, damage behavior reduction level and the peasants' satisfaction. In the ecological variation perception, aeolian sandy soil intention, water resource shortage level plays negative role, and variation of raining or snowing times, coverage level of desertification plants played the positive role. There were positive correlations between family average income per capital, ploughing, the governmental allowance, gender, education level, health conditions among peasant internal factors and peasants' satisfaction. The importance level paid to governance by local government among the controlled variable factors had the positive correlation with peasants' satisfaction. The satisfaction of peasants in plains was significantly higher than that of peasants in mountains. Where male in high education level and good health status resided with more attention given by local government, the satisfaction level of peasants was higher, and satisfaction of plain area was significantly higher than mountain area. Due to the difference between family planning type and income level, relatively big difference existed in the factors influencing peasant policy satisfaction. From policy point of view, paying attention to improvement of peasants' livelihood is the key for the successful fulfillment of future's desertification land sealed protection policy.
