Abstract

The invention discloses a remote real-time monitoring system for soil runoff, belonging to the field of agricultural science. The system comprises a manual simulation rainfall device, a test stand device and a test device, wherein the manual simulation rainfall device comprises a water tank, a safety valve, a constant-pressure pump, a one-way valve, an electromagnetic valve, a flowmeter, a lifting rack and a spray nozzle; the test stand device comprises a table-type test stand, a soil bearing device, a guide hopper, a water container and a filter screen; and the test device comprises a test system and the like. The system disclosed by the invention can conveniently perform monitoring on the rainfall runoff process as well as research on the water erosion mechanism under different gradients, different earth surface conditions and different soil underlying surface conditions, and can realize remote online monitoring on the dynamic phenomenon of soil runoff.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a remote real-time monitoring system for soil runoff. Background technique [0002] At present, soil and land degradation caused by various unreasonable human activities have seriously threatened the sustainability of world agricultural development. According to statistics, the global soil degradation area reaches 19.65 million square kilometers, accounting for 13.10% of the total surface area. In terms of soil degradation types, soil erosion accounts for 84% of the degraded area and is one of the most important causes of soil degradation. Soil water erosion accounts for 56% of global soil erosion and degradation, of which 53% is caused by unreasonable production links of agriculture and animal husbandry. my country is one of the countries and regions with the most severe soil erosion in the world. Soil erosion and its ecological and environmental impacts have...
