摘要

水体叶绿素浓度是水域研究中的重要参量。本文根据在密云水库测量的水体光谱反射比

用多元线性回归方程

估算叶绿素浓度

相关系数大于0.94。逐步回归分析也得到了相似的结果。同时还比较了估算叶绿素浓度的不同方法

讨论了利用陆地卫星MSS

TM和气象卫星CZCS波段反射比数据监测叶绿素浓度的可能性。

Abstract

Chlorophyll concentration in water is an important parameter in waters study. But conventional methods are time-consuming and strenuous. In this paper

the reflectances which chaiacterized the nature of chlorophyll concentration in 400-1100 nm band in spectrum were ased to regress with chlorophyll concentrations which were measured in Reservoir Miyun. According to multi-linear regression equation

the chlorophyll concentrations estimated with correlation coefficient more than 0.94. The similar results were obtained by using step regression analysis. The different methods for estimating chlorophyll concentration were compared and possibility of monitoring chlorophyll concentration in water using reflectance data in Landsat MSS

and Nimbus CZCS bands was discussed.
