地貌成因以冲积、洪积为主的平原区,土地类型及其组成要素之间,渐变和过渡特征明显,利用遥感技术进行土地类型调查,必须采用有别于其它地区的方法。本文以河南省封丘县为例,利用1983年9月和1984年3月航空彩红外影像,并辅以计算机增强的假彩色陆地卫星影像,结合实地调查,做了初步分析。 Geomorphic causes The alluvial, alluvial-dominated plain areas have obvious characteristics of gradual transition and transition between land types and their components. Land type surveys using remote sensing technology must adopt methods different from those in other areas. This article takes Fengqiu County, Henan Province as an example. Based on the aerial color infrared images of September 1983 and March 1984 supplemented by the computer-enhanced false color land satellite imagery combined with the field survey, a preliminary analysis is made.
