基于TM/ETM＋影像的新乡县土地利用演变研究

摘要

Taking Xinxiang county as an example,the paper analyzed evolutions of land use in order to provide scientific basis for intensive use to regional land and sustainable economic and social development.The evolutions of land use of Xinxiang county was analyzed based on multi-temporal Landsat TM/ETM＋ data in 1992 and 2004 in this paper.Considering the correlation matrix of bands and OIF index,optimal bands combination was selected to interpret images,and then the images were categorized.Lastly,Analysis to evolutions of land use was conducted by using SVM classification results.%加强新乡县土地利用演变研究,为新乡县区域土地的集约化利用和经济社会可持续发展提供科学依据。运用多时相Landsat TM/ETM＋影像,综合考虑波段间相关系数和OIF指数,选择最佳波段组合进行图像解译,在此基础上对遥感影像进行分类,并利用SVM分类结果进行新乡县土地利用演变分析。
