摘要：

目前快速城市化地区土地利用变化研究是土地研究的热点之一。为了研究快速城市化地区土地利用变化及其驱动因子，将快速城市化地区划分为城区、郊区和工业主导区3个部分，分2个时段研究了2002—2010年各分区土地利用的时空变化，并分析了土地利用变化驱动因子。研究结果表明，土地利用变化的热点集中在城区和工业主导区；2006—2010年研究区土地利用变化幅度要明显大于2002—2006年，其中两期建设用地分别增加806.40 hm2、3112.91 hm2；耕地、林地等地类大规模减少，二者两期减少之和均占减少总面积的85%以上，建设用地迅速增加；经济发展、外部政策干扰是刺激土地利用变化的主要因素。在土地利用和产业规划过程中进行用地分析，科学实施规划改善土地利用结构，保护水体、林地、耕地等地类，提高土地利用率是保护耕地、林地等地类的关键因素。

Abstract:

The fast city changes area land to use change research is one of the hotspots in the research of land. To study the fast city changes area land to use change and its driving factors, the rapid city area is divided into urban, suburban and industrial dominant area three parts, divided into 2 periods of time were studied the division land use change in 2002-2010, and analyzed the driving factors of land use change. The results showed that: land use change hot concentrated in urban areas and industrial dominant area. The area land uses variation amplitude in 2006-2010 significantly more than 2002-2006, the first time construction land increase 806.40 hectare, 3112.91 hectare for the second time. Farmland, forest land and other land mass reduction, construction land increased rapidly, for the two phases reduced occupy the total reducing area more than 85%. Economic development, external policy interference was the stimulation of main land use change factors. In the land use planning process and industrial land use analysis, scientific planning and implementation of improving the land use structure, protection of water bodies, woodland, farmland land, raise land utilization rate was the key factors for protecting farmland, woodland and other kinds.
