基于卫星遥感影像的新增耕地利用状况动态监测与评价

Dynamic Monitoring and Evaluation of Newly-Increased Cultivated Land Utilization Based on Satellite Remote Sensing Image

以湖南省平江县为研究区,利用2008、2010和2012年3期卫星遥感影像数据,结合新增耕地相关资料、土地利用资料等,提取新增耕地利用状况信息,并建立了评价模型,对研究区2007年新增耕地近5年来的耕地利用情况进行了监测和评价,以期获得研究区2007年度新增耕地的利用状况和利用水平等信息。

With Pingiiang County in Hunan Province as study area, using satellite remote sensing data in 2008, 2010 and 2012, combined with new increased cultivated land relevant data, land use data, the utilization status inflrmation of new increased cultivated land was extrac- ted, the evaluation model was established. The utilization status of new increased cultivated land in recent 5 years were monitored and evaluated, so as to obtain the utilization status and levels of new cultivated land in 2007 in study area.
