【摘要】 耕地是关系到整个国家社会稳定和持续发展的根本问题,通过遥感对耕地的动态监测,对优化耕地利用格局,促进经济发展有利.本文运用ENVI 5.3软件对太谷县的遥感影像图进行预处理,解译得到耕地变化图像,然后运用ArcGIS软件提取太谷县耕地面积数据,通过与该地的经济发展水平对比分析得出相关性结论,并分析内容得出近几期太谷县耕地变化的原因,为进一步提高耕地资源的利用率,为太谷未来几年耕地的时间空间变化提供依据.更多还原

【Abstract】 Geographic information technology has been widely used in social economic construction,and is an effective means of land monitoring in a region. Cultivated land is the fundamental problem of social stability and sustainable development in the whole country. The dynamic monitoring of cultivated land by remote sensing is beneficial to optimize the pattern of cultivated land and promote economic development. This paper uses envi 5. 3 software to preprocess the remote sensing image of Taigu county,cuts,fuses,supervised classification to interpret the image of cultivated land,and then uses ArcGIS 10. 22 software to extract Taigu county land area data.Through comparing with the economic development level of the map,and analyzes the causes of the changes in Taigu county,in order to further improve the utilization ratio of cultivated land,and provide basis for the spatial change of arable land in the next few years.更多还原
