The presence of black and odorous water bodies is a pervasive problem that negatively affects the per-ception and productivity of city inhabitants.Therefore,efficient surveillance and administration of this issue is of enormous importance in the current context.This research focuses on Chebei and Yonghe Rivers,which are typi-cal locations with black and odorous waters.The objective of this study was to investigate the remote-sensing response mechanism of urban water bodies with black and odorous characteristics by examining their optical properties.The results showed that ① Remote sensing reflectance values and spectral slopes at 550～580 nm can effectively differentiate between urban black-odor water bodies,normal water bodies,and highly turbid water bodies.② When the concentration of total suspended solids(TSS)exceeds 100mg/L,TSS becomes the primary factor affecting the optical properties of black-odor water quality indicators.③ The inversion model constructed for the key indicators of black-odor demonstrates high accuracy and provides essential guidance for the manage-ment and protection of black-odor water bodies.
