| 摘 要： | 根据2009年6月巢湖32个样点的实测数据,分析巢湖水体漫衰减系数光谱特征、主导因子、空间分布规律以及400-700nm各波段Kd与Kd(490)之间的关系,并在此基础上,建立了Kd的遥感反演模型.结果表明:巢湖水体Kd具有一致的光谱特征,400-600nm之间Kd随波长的增加呈指数衰减趋势,在600-700nm之间的...

| Abstract: | According to the in situ measured data on 32 sampling sites in Lake Chaohu in June 2009,the spectral characteristics of diffuse attenuation coefficient(Kd),dominant factors,spatial distribution,as well as the relationship between Kd and Kd(490) in 400700nm bands were analyzed.On the basis of these analysis,remote sensing inversion model was developed to calculate Kd(490).The results indicate that Kd presented the consistent spectral characteristics.The Kd in 400600nm showed a exponential decay trend,but Kd ... |
