摘要
作者用野外光谱辐射计对伊宁盆地地物的反射率进行了野外测量,并用计算机对基础资料(4个波段、93个地物点的反射率)进行了对应分析。盆地地物可分成水体、积雪、植被、岩石沙土四类,它们的反射光谱各有特点,并与假彩色合成影象之间存在相关关系。某些自然因素对地物的反射光谱特征有一定影响。
Abstract
An in situ field survey of the reflectance of ground objects was made inYining Basin,Xinjiang Autonomous Region.Correspondence analysis of data(reflectance of 93 groud objects in 4 wave bands)obtained in the surveywas taken by computer.The objects in the basin can be divided into 4 kinds,i.e.water body,snow,vegetation,rock-sand-soil.The reflection spectrumsof the objects are correlative with false-colour synthetic pictures.Some naturalfactors,such as the humidity of soil,the weathering of rock outcrops arebound to have certain influence on the reflection spectrum features.
