| 摘 要： | 基于2014年2月19日、2014年6月7日和2014年10月8日的三景资源三号卫星影像分别作为春季、夏季和秋季的代表,以河南省内的丹江口水库为研究区域,采用面向对象的遥感影像监督分类方法进行影像的分割和分类,提取出遥感影像中的水体,并结合南水北调中线工程对水域面积和周围地物的影响对这3个时期的影像进行比较和分析,得出这3个时期水域面积的变化数据。

| Abstract: | Based on three ZY-3 satellite images on February 19,June 7,and October 8 in 2014,as the representative of spring,summer and autumn season respectively,this paper takes the Danjiangkou reservoir area in Henan province as the study area,and then image segmentation and classification was completed by using the object-oriented remote sensing image supervised classification method,and water bodies in remote sensing images were extracted.Comparing images of the three times in combination with the influence of middle route Project of South-to-North Water Diversion on water area and the surrounding terrain,water area change of the three times was summarized. |
