Atmosphere-vegetation-soil body test system capable of controlling and simulating atmospheric natural environment

Abstract

The invention relates to an atmosphere-vegetation-soil body test system capable of controlling and simulating an atmospheric natural environment. The system comprises a climate simulation device, a standard vegetation-soil body experiment device, a data acquisition device and a data analysis device, wherein the climate simulation device comprises a natural environment simulation box and a rainfallsimulation device; a temperature controller and a humidity controller are arranged above the natural environment simulation box and used for controlling and adjusting the temperature and the humidityduring the test, and illumination controllers are arranged around the natural environment simulation box and used for simulating the illumination during the test; the water inlet pipe of a gas collecting bottle in the rainfall simulation device is connected with a water faucet, the water outlet pipe is connected with a spraying component arranged in the natural environment simulation box throughan electromagnetic valve and a water pipe, the water flow is adjusted in a stepless manner through the electromagnetic valve, and the required flow is controlled to simulate various rainfall forms; and the data acquisition device comprises a runoff drainage flowmeter arranged in a runoff drainage unit and measurement units respectively arranged on layered soil column barrels and used for acquiringinfiltration data of a rainfall soil column.

Description

technical field [0001] The invention relates to a natural environment test system, in particular to a covering layer test system capable of controlling and simulating the natural environment. 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 understanding of nature so that p...
