耕地功能变化具有明显的阶段性。日本、韩国、美国及欧洲发达国家耕地功能已普遍转型。中国农业发展及土地利用需求变化与以上国家颇为相似。那么,目前中国耕地功能变化是否也在发生转型?对此,在构建耕地功能变化分析框架与度量方法的基础上,分析1949年以来中国耕地功能变化过程。结果表明,中国耕地功能总体上于2006年开始转型,转型前后耕地功能供需协调与供需错位、供给滞后、形态扭曲并存。在综合考虑以上发达国家经验与中国耕地功能变化过程的基础上,尝试提出耕地多功能管理建议。此外,从耕地功能变化研究框架出发探讨了土地利用转型的研究路径。
Cultivated land function changes have obvious stage. Japan, South Korea, the United States and developed countries in Europe have generally transformed cultivated land functions. China’s agricultural development and changes in land use demand are quite similar to the above countries. So, at present, whether the change of cultivated land function in China is also undergoing transformation? On the basis of constructing the analysis framework and measuring method of cultivated land function change, this paper analyzes the change of cultivated land function in China since 1949. The results showed that the function of arable land in China started to transform as a whole in 2006. Before the transformation, the coordination of supply and demand of cultivated land and the supply and demand were dislocated, the supply lagged and the shape distorted. Based on the above experience of the developed countries and the process of the change of cultivated land function in China, this paper attempts to propose the multi-purpose management of cultivated land. In addition, starting from the study of the change of cultivated land function, this paper discusses the research path of land use transformation.
