青海柴达木盆地地物波谱特征和遥感最佳波段选择

本文叙述了在航空多光谱扫描成像前, 首先要在工作区进行地物波谱测试, 为多光谱扫描成像取得理想效果、选择最佳波段提供依据。1986年在青海柴达木盆地测得了190多个水、土、植被、岩石与盐类沉积物等地物的波谱数据, 经综合整理, 按DS-1260②的可见光到近红外10个波段, 用数理统计的T检验和秩和检验进行青海柴达木盆地找钾盐航空多光谱遥感最佳波段选择的方法探索。

SPECTRAL CHARACTERS AND OPTIMUM BANDS FOR GROUND-COVER IDENTIFICATION IN CHAIDAM BASIN OF QINGHAI PROVINCE

The spectral measurments of ground-cover before the flight with an airborne multispectral scanner in Chaidam Basin, Qinghai Province are represented in this paper, in order to provide the basis for selection of best spectral bands of ground-cover identification. The spectral data over 190 samples to be taken in site, such as water, soil, vagetation, rock and salt ect, has been obtained in 1986. The optimun bands for exploration of potass resources have been selected according to the ten spectral bands in the DS-1260 scanner arranging from visible to near-infrared spectrum, with the help of the T-test and sequence-test methods in statistics.
