重庆市耕地非农化研究

对1997 2003年重庆市耕地非农化过程进行了时空分析, 并在此基础上对影响重庆市耕地数量动态变化的驱动机制进行了探讨, 对如何缓解重庆市耕地非农化提出了对策和建议. 结果表明: 重庆市直辖以来(1997 2003年)耕地非农化面积达20 403 31 hm2, 全市耕地非农化率为0 8%, 且各年期耕地非农化面积和非农化率逐年攀升且波动较大, 耕地非农化区域差异显著, 经济发展水平较高的地区, 一般耕地非农化率较高. 相关分析表明: 经济发展、城镇化和经营土地是重庆市耕地非农化的主要驱动力.

Research of Cultivated Land Non-Agriculturalization in Chongqing

The paper analyses the space-time character of the process of cultivated land non-agriculturalization in Chongqing during 1997 to 2003 and explores the drive factors. At last, the paper gives some advice on how to slow cultivated land non-agriculturalization in Chongqing. The area of cultivated land non-agriculturalization is 20 403.31 hm~2 and the ratio of cultivated land non-agriculturalization is 0.8% in Chongqing during 1997 to 2003. The area and ratio of cultivated land non-agriculturalization fluctuate under the total increase direction. The differences among districts are obvious. The districts of higher level of economic development have the higher ratio of cultivated land non-agriculturalization. The economic development, urbanlization development and land management are the main drive forces.
