摘要
1997年 8- 9月期间 ,野外调查了吉兰泰盐湖及其外围的 2 5个典型地物 ,并对其实地进行了 10个通道的光谱反射率测试 .根据吉兰泰盐湖地物地学特征 ,可将所测得的 2 5个典型地物分为 5类 :植被、基岩、水体、化学沉积物和松散沉积物 .通过对 5类典型地物波谱反射率特征及其影响因素的研究 ,并依据彩红外航空图象和 TM标准假彩色的成象原理 。
From 1997 August to September, 25 typical surafce surface features were investigated in the field and the reflectivities of 10 channels of them were determined on the spot in Jilantai Salt Lake, Inner mongolia and its periphery. Based on geological characteristics of Jilantai Salt Lake, 25 typical surface features can be divided into 5 types which are vegetation, base rocks, waters, chemical sediments and loose deposits. Through studying the characteristics of the reflectivities of typical surface features and their influencing factors and according to the formation principle of infrared aerial photo and LANDSAT Thematic Mapper (TM) image, the authors established symbols of remote sensing interpretation in Jilantai Salt Lake.
