A water-soil interface physiochemical monitoring apparatus and a reservoir area hydro-fluctuation belt monitoring system based on the same. The water-soil interface physiochemical monitoring apparatus comprises a cylindrical shell, a conical head, a sensor data acquisition circuit, a sealing plug, and a plurality of sensor modules. One end of the cylindrical shell is in sealing connection with the conical head, and the other end is sealed by the sealing plug. The sensor modules are connected to the sensor data acquisition circuit, and are all located in the sealed space of the cylindrical shell. Each sensor module comprises a circuit board, a temperature sensor, a dissolved oxygen sensor and a conductivity sensor, which are combined together by casting using resin, and the temperature sensor, the dissolved oxygen sensor and the conductivity sensor are separately connected to the circuit board.

An experimental system comprises a water level indicator, a data processing module, and an experimental simulator. The water level indicator is connected to the data processing module, and the water level indicator is mounted nearby the experimental simulator when in use. The experimental simulator comprises several experimental units. Each experimental unit comprises a first pipe, a second pipe, and a third pipe, wherein the first pipe perpendicularly communicates with the second pipe, a check valve which allows water to flow out but allows no water to flow in is connected to the water outlet of the second pipe, and the third pipe perpendicularly communicates with the second pipe and is parallel to the first pipe. The heights of the third pipes of the several experimental units are in a decreasing or increasing order.
