| 摘 要： | 以1995、2003与2013年的Landsat TM/OLI影像为数据源,基于CART算法的动态变化分析方法对杨凌示范区1995~2013年的土地利用动态变化情况进行了分析和统计。研究结果表明,1995~2013年18年间杨凌示范区农用地减少了27.65 km~2,林用地减少了16.86 km~2,城市用地增加了41.82 km~2,减少的农用地和林用地主要流向城市用地。通过对自然、社会和经济因素的分析,可知杨凌区土地利用变化主要驱动力为经济和社会因素。

| Abstract: | The dynamic change of land use in Yangling Demonstration Zone was computed and analyzed by using the atmospheric cor -rection, image registration, dynamic change which based on of CART algorithm and that based on 1995, 2003 and 2003 TM /OLI Landsat images as data sources.The results showed that, in the past 18 years, which between 1995 and 2013, the area of farmland reduced 27.65 km2 in yangling demonstration zone , forest land reduced 16.86 km2 , urban land increased 41.82 km2 , reduce farm-land and forest land is mainly flow to the urban land .Through the analysis of the natural , social and economic factors , the main driv-ing force of Yangling Demonstration Zone land use change were the economic and social factors . |
