摘要
区域河流、水库容水资源量对该区的工农业生产和经济发展具有重要的作用,采用遥感影像分类技术对获取区域水系信息具有无可比拟的优越性。本文以山西省大同盆地为研究区,以Landsat TM影像为数据源,采用遥感影像监督分类技术,在ERDAS 9.2下对影像进行预处理并做监督分类,最后通过实地调查验证分类的准确性。研究结果表明,2005年9月份该区水系占地面积148.48km2,占该区总面积的2.12%。通过本次研究工作,可对大同、朔州地区的可持续发展提供基础信息支持。
Area rivers, reservoirs Yung quantity of water has an important role in the area of industrial and agricultural production and economic development, the use of remote sensing image classification techniques to obtain regional water system has incomparable superiority. To Datong Basin study area, the Landsat TM image data source using the technolo- gy of remote sensing image supervised classification in ERDAS 9.2 image preprocessing and do supervised classification, and finally through the field survey validation classification accuracy. The results show that in September 2005, the dis- trict water system area of 148.48 km2 , accounting for 2.12% of the area of the total area. Through this research, can provide basic information on the Datong, Shuozhou region, sustainable development support.
