快速城镇化过程中的小区域土地利用变化及其驱动力分析——以杭州市千岛湖镇为例

在分析1993—2004年千岛湖镇土地利用变化特征和驱动力的基础上，揭示了千岛湖镇土地利用的时空分异特征。结果表明，土地利用变化以城镇及工矿用地的输入和林地的输出为主要特点；耕地、林地、未利用地和其他未利用地的转出面积超过转入面积，而园地、其他农用地、交通用地、水利设施用地和城镇及工矿用地则相反；自然因素、城镇化、农业结构调整、比较经济利益、交通条件和政策因素是引起其土地利用变化的主要驱动力因子，距一级干道的距离是最重要的自然驱动因子。

Analysis of Land Use Change and Its Driving Forces in a Small Region Scale in Rapid Urbanization Stage

Based on analyzing the driving force of land use change characteristics in Qiandaohu Town, Hangzhou City from 1993 to 2004, the dynamic trend and degree of land use in the district was analyzed by spatial analysis of GIS, and its driving forces were also discussed and e- valuated. The results showed that the main characteristics of land use ehange were the input of urban and industrial and mining land and the output of forest land. The output area of cultivated land, forest land, idle land and other idle land exceeded its input area. However the area changes of garden land, other agricultural land, water facilities land and urban area and mining land were opposite. Factors, such as the natu- ral factor, urbanization, structure adjust of agriculture, economic benefits, traffic development and national policy were the main driving forces that caused land use changes in this district. The distance to the federal highway was the most important natural driving factor.
