Surface and soil water storage capacity integrated measuring instrument

Abstract

The invention relates to a surface and soil water storage capacity integrated measuring instrument. The surface and soil water storage capacity integrated measuring instrument comprises a soil water storage capacity measuring instrument and a water pipe, wherein the soil water storage capacity measuring instrument is located under the ground surface; the water pipe comprises an upper pipe located on the ground surface and a lower pipe located under the ground surface; a communicating pipe I capable of being communicated with the outside is arranged at the junction of the upper pipe and the lower pipe; the upper pipe, the lower pipe and the communicating pipe I are mutually communicated; a piston capable of sliding along the pipe wall is arranged in the lower pipe of the water pipe; a traction motor pushes the piston to move up and down in the lower pipe and is in signal connection with the soil water storage capacity measuring instrument. The surface and soil water storage capacity integrated measuring instrument realizes integrated monitoring of the surface and oil water storage capacities, and boundary change processes such as evaporation and permeation.

Description

Technical field [0001] The invention relates to the field of hydrological measurement, in particular to a measuring instrument suitable for monitoring the surface environment of wetlands and other wetlands. The measuring instrument realizes the joint monitoring of surface and soil water storage and evapotranspiration and other interface change processes, especially wetlands Wait for the water interface transformation and joint measurement in the wet surface environment. Background technique [0002] The temporal and spatial changes of surface and soil water storage are important monitoring indicators for the natural ecological environment such as wetlands. The temporal and spatial changes of surface water and soil water, as well as the transformation between the surface and the soil, also affect the ecological process of the natural ecosystem of the landing site. Succession pattern. In order to quantitatively monitor the hydrological fluctuation characteristics of the natural su...

Problems solved by technology

[0005] Traditional small water surface evaporation instruments are often placed in mid-air above 70cm above the ground, away from the real environment of the ground surface, and the measurement accuracy is not high. Traditional large water surface evaporation instruments are particularly inconvenient to install due to their bulky volume
