Abstract
The invention discloses an experimental device and method based on non-point source pollution of a karst binary space structure, belongs to the field of environmental pollution experiments, and solves the problem that pollution research of a binary space structure cannot be performed on soil in a karst region in the prior art. An experimental device is fixedly arranged below the spraying device, soil is contained in the experimental device, the upper end of the experimental device is connected with an earth surface collecting tank, the lower end of the experimental device is connected with an underground collecting tank, and a water through hole and a pore adjusting device are arranged in the experimental device; the research on surface and underground pollution of a binary space structure in the karst region is realized, and the technical effect of collecting surface water and underground water is realized.
Description
technical field [0001] The invention belongs to the field of environmental pollution experiments, and in particular relates to an experimental device and method for surface source pollution based on karst binary space structure. Background technique [0002] Agricultural non-point source pollution has become a serious environmental problem of common concern in the world. Agricultural non-point source pollution control is an effective way to achieve a healthy agricultural production environment, and at the same time provides a path and guarantee for the green development of agriculture. [0003] In the karst region of southwest China, the surface carbonate rocks are exposed and the ecological environment is fragile. The special geological background and soil-forming environment in the karst area. As a result, the area has few soil-forming substances, barren and intermittent soil, and extremely scarce agricultural land resources. Social, economic, and educational developmen...
