Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a comprehensive rock weathering experimental platform to solve the problem of rock weathering monitoring in the prior art relying on burying rock test pieces in the field and measuring their weight changes. Sample sampling work is labor-intensive, time-consuming and labor-intensive, and there are technical problems such as sample deterioration during long-distance transportation; it is impossible to perform long-term real-time dynamic monitoring of rock weathering at different depths and related driving factors

example 1

[0024] Example 1: Studying the hydrological process and soil geochemical state of the karst ecosystem

[0025] refer to figure 1 , open the rear side back panel of the sample box, fill in mixed samples of lime soil, limestone and dolomite, the height is flush with the scale of the sample box, fasten the back panel of the sample box, hang the sample box on the sample box weight measuring instrument, put The water seepage receiving device is directly under the sample box, and placed on the weight monitor of the water seepage receiving device, wrap the sample box and the water seepage receiving device with a non-transparent film, and read the sample box on the sample box weight measuring instrument after the sample box is stable Weight, temperature and wind speed parameters. Set the timing quantitative drainage controller according to the actual rainfall situation, so that it can automatically drain the sample box every day to simulate the quantitative rainfall. Open the soil w...

[0026] Example 2: Research on rock weathering driving factors and carbon sink inversion model

[0027] refer to figure 1 According to the scheme of Example 1, the experimental platform was built, and lime soil was filled in the sample box, and the dolomite rock test piece was buried at a specific depth, and the timing and quantitative drainage controller was set to allow it to automatically drain the sample box every day to simulate quantitative rainfall. At the same time, parameters such as wind speed, evapotranspiration, soil moisture at each depth, temperature, pH, and ion concentration are regularly measured. Take out the rock test piece regularly every month to measure its dry weight change, so as to measure the weathering rate of the rock test piece at different depths, and put it back to the original position after the measurement. The contribution rate of each factor to the rock weathering rate can be calculated by exploring the relationship between the weathering rat...

Abstract

The invention discloses a rock weathering comprehensive experiment platform. The rock weathering comprehensive experiment platform comprises a steel rack (100) and is characterized in that a sample box weight measuring instrument (110) is fixed to the lower bottom surface of the steel rack (100), a sample box (103) is fixedly connected to the weighing hook of the sample box weight measuring instrument (110), and a seeped-water receiving device (108) is arranged at the bottom of the sample box (103); the seeped-water receiving device (108) is placed on the weighing platform of a seeped-water receiving device weight monitoring instrument (109); the water outlet pipe of a model rainfall system extends into the top of the sample box (103); a soil water draining pipe (104) and a temperature monitor probe interface (105) are arranged on the left side and the right side of the sample box (103). By the rock weathering comprehensive experiment platform, the technical problems that weathering monitoring in the prior art is performed by burying rock pieces in the open field and measuring the weight change of the test pieces, a large amount related sampling work needs to be performed in the open field, the rock weathering monitoring is high in labor intensity, time-consuming and labor-consuming, and samples may deteriorate during long-distance transportation; the weathering monitoring in the prior art cannot perform long-term real-time monitoring on different-depth rock weathering and related drive factors, and the like are solved.

Description

technical field [0001] The invention belongs to rock weathering measurement technology, in particular to a rock weathering comprehensive experiment platform. Background technique [0002] Rock weathering is one of the important contents of the research on the evolution of ecological environment in karst areas. The systematic study of rock weathering is of great significance to solve the ecological security pattern and the imbalance of terrestrial carbon sink income and expenditure in karst areas. The current mainstream rock weathering flux monitoring scheme mainly depends on burying rock test pieces in the field and measuring their weight changes. There are problems such as sample deterioration during transportation. Most importantly, long-term real-time dynamic monitoring of rock weathering at different depths and its related driving factors is impossible. This has led to a series of issues that researchers have been unclear about the correlation and contribution rate of ...
