| 摘 要： | 在构思地块尺度耕地社会保障功能价值测算方法,测算调查水田、旱地地块社会保障功能价值的基础上,识别耕地社会保障功能价值影响机理,构建促进耕地社会保障功能价值供需平衡的综合措施体系.结果表明:①水田地块的社会保障功能价值水平总体高于旱地地块,耕地地块复种指数越高、经济作物种植比例越高,越利于耕地地块社会保障功能作用的发挥；②耕地地块社会保障功能价值受到农户家庭人均耕地面积和农户家庭农业人口人均非农纯收入因子的显著负影响,受到耕地地块地均纯收益因子的显著正影响；③要促进耕地社会保障功能供需平衡,一要通过增加耕地资源数量和提高耕地资源的物质产品产出能力来提升耕地资源的社会保障功能供给能力,二要从提高农户家庭的非农收入水平、加快农村人口向城镇转移、进一步加强农村社会保障体系的建设与完善来减弱人类对耕地资源社会保障功能的依赖程度.

| Abstract: | Here,we determine a method for calculating the social security function of cultivated land plots and survey social security and cultivated land across three villages. Through this process, the mechanism underlying the social security function value of cultivated land was recognized,and a comprehensive system to promote social security functional balance between supply and demand, was constructed. The results suggest that the value of paddy field social security function per unit area in three villages is higher than that of dry fields. The social security function value of plots with a high multiple cropping index was generally greater than that of traditional planting plots, indicating that a higher multiple cropping index and economic crop proportion is better for social security function. The per capita cultivated land area of rural households and the per capita non-farm income of farmers had a negative impact on the social security function value of cultivated land. The net income of cultivated land per unit area had a positive impact on the social security function value of cultivated land. To promote balance between the social security function of the supply and demand of cultivated land,we should (1) enhance the social security supply capacity of cultivated land resources by increasing the amount of cultivated land resources;(2) improve the material goods output capacity of cultivated land resources;(3) weaken our dependence on the social security function of cultivated land resources by increasing non-farm income for rural households;(4) speed up the transfer of rural populations to urban areas,and (5) further strengthen the rural social security system. |
