Problems solved by technology

However, manual measurement cannot realize the process monitoring of water volume, and when the water volume such as heavy rain is too large, especially when the experimental environment is harsh at night, manual measurement cannot complete data collection in time, which may lead to data loss and loss of experimental data
The rain gauge can be used for water dynamic research, but due to the limitation of the working range, it cannot meet the monitoring of large flow

Abstract

A long-term forest eco-hydrology water yield automation dynamic measurement method and device relate to a forest eco-hydrology water yield measurement method and device. The invention aims at solving the problems that dynamic process research cannot be realized by the existing artificial measurement, the artificial measurement precision is low, and unpredictable data loss is caused by a harsh environment. The method comprises the steps: a measurement point is selected, a sample land is built, and a penetration rain water flow rate, a trunk runoff flow rate and a surface and soil runoff flow rate are obtained by utilizing an eco-hydrology water yield dynamic measurement device and calculating with corresponding flow rate formulas. The device comprises that a plug of a lower end port of a water level measuring tank is drilled to mount an ABS water tank joint, the ABS water tank joint is connected with a normally closed solenoid valve and a liquid level transmitter, water level probes are mounted on a water level measuring barrel, a solar cell panel is erected, and the solar cell panel, the liquid level transmitter, the water level probe I, the water level probe II and the solenoid valve are connected to a controller. The invention is used for long-term forest eco-hydrology water yield automation dynamic measurement.

Description

technical field [0001] The invention relates to a method and device for measuring forest ecological hydrological water volume, in particular to a method and device for long-term automatic and dynamic measurement of surface, soil runoff, tree trunk runoff and penetrating rainwater, which belong to the method and device for measuring ecological and hydrological physical property indicators. Its field of measuring instruments. Background technique [0002] Water is an important material in the material cycle of the forest ecosystem, and it also participates in the regulation and control of the forest ecosystem as the main carrier of the material and energy cycle of the system and the forest eco-hydrological process. The water in the forest ecosystem is mainly input through precipitation, but affected by the forest, the precipitation is redistributed during the input process, enters the forest in the form of tree trunk runoff and penetrating rain, and then collects in the forest...
