| 摘 要： | 以太湖和石头口门水库为例,建立了一种可直接计算水体叶绿素a浓度的区域化三波段模型。该模型通过对研究水体的光学特性分析,明确三波段组合与叶绿素a浓度间的函数关系参数,不仅可较好指示研究水体叶绿素a浓度水平,而且大大减小了回归算法所带来的模型不确定性。利用高精度、长时间序列的水体光学特性观测数据,建立针对不同研究水体的区域化三波段模型可为实现内陆水体叶绿素a浓度遥感监测业务化运行提供方法借鉴。

| Abstract: | we presented a newly regional three-band model to estimate Chla (Chlorophyll-a) directly by a case study in Taihu Lake and Shitoukoumen Reservoir. Inherent optical properties of the target waters were investigated to determine the model coeffi cients describing the relationship between three-band combination and Chla concentration. Results show that the proposed model is intended to both provide high accuracy and greatly reduce the uncertainty caused by regression algorithms. Based on the accurate and long-term water optical observations, the regional three-band models designed for different water areas would promote the operational monitoring of Chla in inland waters. |
