太湖遥感反射率变化特征及其影响因素分析
An Analysis of the Variation Features and Influential Factors of the Remote Sensing Reflectance of the Taihu Lake
摘要
Abstract
The spectral data and numerical analyses of the Taihu Lake during the period of October 4 -8, 2010 were used to analyze the influence of solar zenith θ, the ratio of scattering and absorption coefficient b/a and parameter Q upon the variation of remote sensing reflectance. According to the results, remote sensing reflectance increases with solar zenith θ, while θ changes in the range of 0° ~20° or 80°~89°, which has little influence on the growth of remote sensing reflectance. Remote sensing reflectance increases with the increase of b/a, and there obviously exists a positive relation between them. When Q is large (6 ~ 7) , its alteration has little effect on the variation of remote sensing reflectance. On the contrary, when Q is small (2 ~3), its variation has enormous impact on the growth of remote sensing reflectance. Remote sensing reflectance tends to decrease with the growth of Q.关键词
