Summary: | The invention relates to an underwater optical sensing technology, in particular to a water body multi-wavelength attenuation coefficient measuring method and a water body multi-wavelength attenuation coefficient measuring system, and aims to overcome the defects of low measuring precision and large error of a water body multi-wavelength attenuation coefficient measuring method and a water body multi-wavelength attenuation coefficient measuring system in the prior art. The method for measuring the multi-wavelength attenuation coefficient of the water body comprises the following steps: emitting a laser signal in the water body to be measured, receiving the laser signal at a first receiving distance, and obtaining an optical power value I1 at the first receiving distance according to the received laser signal; adjusting the distance between the emitting laser signal and the receiving laser signal as a second receiving distance to obtain an optical power value I2 under the second receiving distance; according t |
