武昌东湖水体污染的航空遥感分析

本文以彩红外航片为主要判释资料,采用航空摄影与地面同步测量的方法,对东湖水体污染状况进行分析。结果表明,凡是能造成水色差异的污染物质,都能在影像色彩和水体光谱亮度值上反应出来。污染物质的类型、浓度与其光谱亮度值具有某种相关关系。根据影像特征和光谱亮度值,结合水样分析和地面调查,可较快地确定水体类型,营养状态,稀释扩散方向。

THE ANALYSIS THROUGH AEROSPACE REMOTE SENSING OF WATER POLLUTION IN EAST LAKE,WUHAN

The state of water pollution in East Lake is analysed in this article by using the method of synchronizing aerial photography and earth measurement, by taking the color infrared aerial photography as a main interpretation material. The result shows that all pollutant which can make difference in water optical spectrum brightness. The certain correlations among pollutant's type, consistency and optical brightness. The water type, nutrition state and dilution spreed direction can be determined quickly by image feature and optical spectrum bright value,as'well as the water biochemical analysis and ground survey.
