摘要

为了明确三峡库区(重庆段)各区(县)城市化阶段与粮食播种面积变化驱动力分区,并明确对应城市化阶段与粮食播种面积变化驱动力分区之间的关系,笔者运用了统计分析法、层次分析法、模糊综合评价法进行研究。研究结果表明:(1)研究区城市化率增长速度快,根据城市化率确定了不同时期各区(县)所处的城市化阶段;(2)粮食播种面积总体上呈现下降趋势与“适度增加—急剧减少—小幅增加—小幅减少”的状态,并且区(县)差异明显;(3)粮食播种面积驱动力空间分区可分为最优型经济福利—生态安全驱动区、最优型经济福利—粮食安全驱动区、生存型经济福利—粮食安全驱动区;(4)确定了研究区城市化阶段与粮食播种面积变化驱动力分区的对应关系。此项研究有利于缓和粮食安全保障与经济发展的矛盾,也可为研究区制定差异化的粮食安全保障措施提供参考。

Abstract

To define the urbanization stage of the Three Gorges Reservoir Area (Chongqing section) and the driving forces of grain sowing area, and analyze the relationship between these two, the authors used the statistical analysis method, AHP, fuzzy comprehensive evaluation method to conduct the study. The results showed that (1) the rate of urbanization in the study area increased fast, and the levels of urbanization of different districts (counties) were recognized by urbanization rate; (2) the grain sowing area showed a downward trend and a “moderate increase- sharp decrease- slight increase- slight decrease” trend, and the difference among districts (counties) was obvious; (3) the change of the driving forces of grain sowing area could be divided into three kinds of spatial regions: the most superior economical welfare-ecological safety driving area, the most superior economical welfare-grain safety driving area and the survival economical welfare-grain safety driving area; (4) the relationship between the urbanization stage and the driving forces of grain sowing area was determined. This study could ease the contradiction between food security and economic development, and provide reference for the study area to make different food security measures.
