Background

The wetland hydrological survey is a statistical behavior for acquiring wetland hydrological situation changes, is a basic way for mastering the supplement, diameter and discharge conditions of wetland water, defining a wetland water circulation mechanism and selecting a wetland long-acting supplement water source, and is an important data source for supporting wetland ecological evaluation, protection and recovery. The scientific and applicable investigation device is a material basis for developing wetland hydrological research, and the efficient and accurate investigation method is a key link for promoting the modern wetland ecological hydrological observation system to be improved day by day.

The current wetland surface water level monitoring method mainly comprises three methods of self-gauging water level gauge measurement, water gauge measurement and manual handheld water level gauge measurement. The self-metering water level meter has the characteristics of automatic recording and remote control, but the purchase cost is high, the device layout process is complicated and easy to lose, and meanwhile, the self-metering water level meter is limited by a factory-set recording threshold value and is not suitable for surface water measurement in a large area; the water gauge device is low in cost, but is limited by subjective factors of visual level conditions and objective conditions such as wind waves, barriers, water blocking and blocking, and the like, and the accuracy level of measurement results is low. When the water level is measured by manually using the handheld water level gauge, a fixed reference object is not available, the reference elevation measurement is inaccurate, the multiple measurement positions cannot be accurate to the same place, and the water level is greatly disturbed by the outside. Therefore, how to prepare an investigation device which has high measurement accuracy, low cost, suitability for large-scale arrangement and low interference degree to the ecological environment and a scientific and efficient investigation method matched with the investigation device become important problems to be solved in the field of wetland hydrological investigation.
