| 摘 要： | 利用大比例尺低空遥感飞行所获得的多光谱图象和地面同步、准同步测量的各种数据,经过理论分析,公式推导,先得出于桥水库叶绿素浓度与水的双向反射率的复相关关系;并对所获取的120张多光谱图象进行几何校正、镶嵌等恢复处理,建立精确的水体双向反射率和图象光学密度的关系。依靠这些关系计算出于桥水库内浮游植物叶绿素α的含量。分析结果表明:利用遥感的宏观优势,配合必要的实地测量,可以较精确地对内陆水域的叶绿素分布进行数值估算,它是一种监测内湖水域营养状态极为有力的手段。

| Abstract: | In this paper,by using the remotely sensed multi-spectral images,which are of large scale, and series of measurements taken simultaneously on the ground, estimates of the chlorophyll distribution, which is a principal index of nutrient laden in Yuqiao Reservoir,are made quantitatively with employing such a technique as complex correlation and paying more attention to the optical characteristics of chlorophyll. This approach is a means to monitor nutrient laden in the lakes. |
