摘　　要：用野外光谱仪与航摄同步对苏南大运河水体进行水质测定的17个同步采样断面进行光谱测试,以TM波段与水体有机污染参数DO、COD_(Mn)、BOD_5、NH_3-N、NO_2-N、石油类和有机污染综合评价A值进行相关分析和多元回归分析。结果表明,水体反射光谱与有机污染参数高度相关,并以A值、BOD_5、DO、COD_(Mn)对R、TM_2,TM_1的贡献最大,为水遥感研究、解译、分类和水质遥感定最分析提供了基础和依据。In the remote sensing study on water pollution of the Grand Canal through southern Jiangsu,17 cross sections of water body of the canal,from which were simultaneously taken the samples for the determination of water quality,were synchronously measured using a field spectrum analyzer and the aerophotography. The correlative analysis and multiple regression analysis were carried out on the TM wave band and water organic pollution coefficients such as DO,CODMn,BOD5、NH3-N,NO2-N and A value as a comprehensive evaluation A value of oil and organic pollution. Results show that the reflection spectrum of water body was highly correlated with the organic pollution coefficient; and A value, BOD5, DO and CODMn made the highest contribution to RTM2 TM1, which provide a scientific basis for water remote sensing study, interpretation , classification and the remote sensing quantitative analysis of water quality.
