【摘要】：利用全国(港澳台地区除外)1985—2013年的面板数据,分析各省份城镇化水平的演进态势及耕地数量的动态变化,并分不同时段测算各省份城镇化发展水平与耕地资源变动的耦合协调程度。结果表明:(1)1985年以来,全国大部分地区的城镇化水平整体上都呈现上升的变化趋势,东三省城镇化水平稳定上升但活力不足,西北多省份上升中波动较大,西南地区水平偏低。(2)全国耕地资源在20世纪80年代普遍减少,后期多省份有所增加,但京、津、沪、苏、粤等地的耕地面积一直在以一定的速率减少。(3)全国城镇化与耕地资源关系的协调度呈现西高东低、北高南低的空间格局。较多地区在快速城镇化进程中城镇化发展与耕地资源的协调度呈恶化趋势。
[Abstract]:Using the panel data from 1985 to 2013 in the whole country (excluding Hong Kong, Macao and Taiwan), the paper analyzes the evolution of urbanization level and the dynamic change of cultivated land quantity in each province. The coupling coordination degree between urbanization development level and cultivated land resource change was calculated in different periods. The results show that since 1985, the urbanization level in most parts of the country has been on the rise. The urbanization level in the three East provinces has been steadily rising but its vitality is insufficient. The level of cultivated land in southwest China was on the low side. (2) in the 1980s, the cultivated land resources of the whole country generally decreased, and in the latter period many provinces increased, but Beijing, Tianjin, Shanghai, and the Soviet Union, The cultivated land area in Guangdong and other places has been decreasing at a certain rate. (3) the coordination degree between urbanization and cultivated land resources in China presents a spatial pattern of high in west and low in east and low in north and south. In the process of rapid urbanization, the degree of coordination between urbanization and cultivated land resources is worsening.
