摘要: 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。

Abstract: With obvious phase characteristics, cultivated land function changes in Japan, South Korea, USA, and European developed countries share a common experience of transition. Agricultural development and land use demand change in China are similar to the situation in the above countries. Clarifying whether cultivated land function transition are occurring in China is of significance to cultivated land management. This paper aims at depicting the evolving cultivated land function in China since 1949. First, the research framework of cultivated land function change coupled by policy development analysis and quantitative assessment is established. Then, methods of measurement of cultivated land functions are proposed. Results show that cultivated land function transition was found in 2006. It is worthwhile that co-ordination and malposition of supply and demand of cultivated land functions coexisted with supply lag and function morphology distortion. Considering the experiences in the above developed countries and cultivated land function change in China, this paper proposes suggestions on multifunctional management of cultivated land. In addition, route of land use transition research is discussed based on the research framework of cultivated land function change.
