基于RS技术的洪泽湖周边地区遥感影像信息提取

摘要

Hongze lake, China's fourth largest freshwater lake, in the west of jiangsu province huai river down-stream. This study of the surrounding areas including Sihong Country and HongZe Country, Siyang Country, XuYi Country and part of Huai'an city. Using remote sensing and geographic information system technology, this paper firstly have a geometric correction of remote sensing images in 2010 with administrative zoning map in the study area, and then get Hongze lake surrounding range of remote sensing image information, provide the basis of remote sensing information source for the land use and ecological effect research in Hongze lake surrounding areas.%洪泽湖，中国第四大淡水湖，在江苏省西部淮河下游。本次研究的周边地区包括泗洪县、洪泽县、泗阳县、盱眙县，还有淮安市区中的一部分。本文运用遥感和地理信息系统技术，先用研究区的行政区划图对2010年遥感影像进行几何校正，再进行裁减获得洪泽湖周边范围遥感影像信息，为后期洪泽湖周边地区土地利用及生态效应影响等研究提供基础遥感信息源。
