Abstract

The invention relates to a super-humid earth surface environment water lysimeter. The lysimeter is vertically inserted into soil. The lysimeter comprises an outer frame and a plurality of water storage devices, which are arranged in the outer frame and in different depths; at least one water storage device is provided with a descending water collecting sheet; a horizontal pushing device can push the descending water collecting sheet to horizontally slide relative to the water storage device and stretch out from the outer frame; and the water storage device and the horizontal pushing device are connected to a central processing module through a circuit. The lysimeter can be used to monitor the super-humid earth surface environment such as wetland, and the like; can detect the soil evapotranspiration and infiltration amount and earth surface evapotranspiration and infiltration amount, and is especially suitable for the monitoring on super-humid earth surface environment such as wetland, and the like.

Description

technical field [0001] The invention relates to a lysimeter, which is suitable for hydrological lysimeter process detection in a natural state, in particular to a lysimeter for monitoring in wetland and other over-humid surface environments. Background technique [0002] Evaporation and infiltration are important contents of hydrological monitoring. Evaporation mainly includes soil water evaporation and water surface evaporation, and infiltration is divided into soil saturated infiltration and unsaturated infiltration. [0003] Most traditional soil lysimeters can only measure soil infiltration and soil water evaporation under unsaturated conditions. When the soil water content is saturated and the surface is waterlogged, it cannot measure soil infiltration and water surface evaporation. Therefore, the traditional lysimetry instrument is not suitable for the measurement of the water accumulation area, only suitable for the field measurement. [0004] Traditional small water...
