A device for stratified in-situ monitoring of the water quality and dissolved oxygen of sediments in a tidal river network region includes a floating platform. Three take-up and pay-off assemblies are fixedly connected to the edge of a top surface of the floating platform. The device can provide high-density data of stratified dissolved oxygen, all monitoring units perform sampling and monitoring directly at the positions where they are located, samples do not need to be transferred, sediments will not be disturbed, and monitoring is performed in the field environment, such that researchers can obtain the long-term diurnal change of stratified dissolved oxygen and the continuous change process of dissolved oxygen in one and even multiple hydrologic years, and basic data is provided for study of the dissolved oxygen change mechanism and accurate control of the water environment in tidal river network regions.

Disclosed is a method for carrying out ecological water supplement by using tidal power, including the following steps: constructing a first water supplying river channel at an upper and middle reach of an artery and tributaries of a river channel, storing water at high tide and supplying water to the tributaries at low tide based on the first water supplying river channel; and setting a storage tank at an urban river channel, constructing a second water supplying river channel at an other end of the storage tank connected with the urban river channel, and supplying the water to a city based on the interconnected storage tank, the urban river channel and the second water supplying river channel.
