传统测量水中悬浮物质如泥沙、叶绿素等的方法是通过大面积、大范围的逐点采样,存在着速度慢、周期长、成本较高等不足,不利于进行区域的科学研究。而利用水体光谱分析能够克服以上诸多缺点。本文分析了含沙水体、含叶绿素水体及污染水体等水体的光谱特征,阐述了利用水体光谱的分析来测定水中泥沙、叶绿素含量的方法和原理,从而说明水体光谱分析法在遥感解译方面的应用及其重要意义,并讨论了光谱分析法在这些具体应用中存在的某些缺点和不足,提出了可行的解决方法。 更多还原

【Abstract】 The traditional measurement of suspended material in the water such as sediment,chlorophyll and so is sampling point by point in a large area,which is slow,long period and high cost,and is not conducive to scientific research in the region.But the using of water spectral analysis can overcome such shortcomings above.This paper analyzes the characteristics of the spectral of the sandy water,,the water with chlorophyll and the polluted water,and describes the methods and theories of the using of w...
