Vegetation covering layer model box for simulating climatic environment change and rainfall space-time change

Abstract

The invention relates to a vegetation covering layer model box for simulating the climatic environment change and rainfall space-time change. A climatic environment simulation unit comprises temperature and humidity controllers which are connected with the model box, an illumination controller and an environment simulation chamber; a water tank in a rainfall simulation unit is connected with a water pump, two electromagnetic valves and multiple irrigation spray nozzles in sequence to form a rainfall loop; a testing platform unit is arranged under the rainfall simulation unit and comprises thevegetation covering layer model box with a changeable inclination angle, multiple drainage rods arranged in the vegetation covering layer model box, multiple water tanks communicated with the drainagerods and multiple sensor embedding holes formed in the vegetation covering layer model box; a data collection analysis unit comprises multiple tensiometers, multiple soil moisture sensors, multiple water feeding flowmeters, multiple drainage flowmeters and a sensor data collection module, wherein the tensiometers and the soil moisture sensors are arranged in the sensor embedding holes respectively; a computer control module is connected with the sensor data collection module and an electromagnetic valve control module separately.

Description

technical field [0001] The invention relates to a vegetation cover model box, in particular to a vegetation cover model box capable of simulating climate environment changes and rainfall temporal and spatial changes. Background technique [0002] During the rapid economic development in China and the construction of a large number of civil engineering projects, the destruction of vegetation has led to the emergence of some geotechnical problems. For example, rainfall caused a large number of shallow slope damage and surface erosion, and severe weather such as sandstorms occurred successively in the northern and western regions, which not only destroyed the ecological environment, but also threatened the safety of people's lives and property. [0003] Nature provides human beings with a harmonious and beautiful living environment, which should be cherished and protected. Researchers should strengthen interdisciplinary cooperation to gain a comprehensive and in-depth understa...
