| 介绍了1980-2011年陕西省耕地面积的变化态势，对影响陕西省耕地面积变化的驱动因素进行分析，指出陕西省耕地面积变化受政策因素和社会-经济-农业系统因素共同影响。其中，政策因素一方面在促进城镇化、工业化进程当中使得耕地面积减少，另一方面为了保障粮食安全，保护耕地红线，又通过政策因素来抑制耕地过快和非理性减少；社会系统因素中由于人口的不断增加和城市化进程的不断加快，进而导致耕地面积减少；经济系统因素中耕地面积的变化是由投资、外延扩张以及农业经济调整引致的；农业系统因素主要是通过农业科技要素影响耕地面积变化的。在实证定量分析的基础上，有针对性地提出了城市土地集约利用水平、实现区域耕地动态平衡等对策建议。 |
