摘要
通过研究MODIS遥感数据与太湖现场监测数据之间的规律,确定了一个基于MODIS数据的叶绿素a指数,并以此为基础构建出一个具有普适性的、反映太湖叶绿素a时空分布动态变化的反演模型,为太湖藻类爆发的机理、预警研究以及水环境管理累积数据,提供决策依据。
Based on the correlation analysis of MODIS data and field meast, rement results, the chlorophyll-a index was achieved. And an empirical algorithm has been constructed, which could describe the spatial-temporal distribution of chlorophyll-a in Taihu Lake. Application of MODIS image in water quality observation will accumulate data for mechanism and forecast of alga breaking out and provide basis for the decision-making of water environment management.
