Embodiment Construction
[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0023] Such as figure 1 , a field monitoring system for field slope soil infiltration performance proposed by the embodiment of the present invention, which includes a pit 2, which is dug vertically on the slope 1, preferably, the pit 2 is an L-shaped groove, and its bottom surface is horizontal Or tilt downward, so that the water flowing into the pit 2 flows out along the bottom of the pit, so as not to accumulate in the pit 2, which will bring inconvenience to the monitoring; In the slope 1, the lower end of the sump 3 is exposed from the side wall of the pit. When the water seeps into the sump 3, since the sump is placed along the slope, the water is subjected to the a...

The invention relates to the field of monitoring of soil infiltration capacity, and particularly relates to a field monitoring system for infiltration property of wild hillside soil. The field monitoring system comprises a header tank, a pit slot and a water receiver, wherein a notch of the header tank is upward and arranged inside the hillside field along the inclination direction of the hillside field; the pit slot is vertically dug on the hillside field and the lower end of the header tank is exposed outside; a water inlet is formed on the water receiver; the water inlet of the water receiver is arranged below the notch at the lower end of the header tank. The pit slot is dug on the hillside field, the header tank in the hillside field and the water receiver at the lower end of the header tank are arranged, the infiltration time and the infiltration capacity of rainfall of the hillside field are monitored, and the infiltration rate is calculated, so as to reflect the infiltration property of the hillside soil. The monitoring system is simple in structure, convenient to carry out and low in cost.
Description
technical field [0001] The invention relates to the field of soil infiltration capacity monitoring, in particular to an on-site monitoring system for field slope soil infiltration performance. Background technique [0002] Soil infiltration is an important part of ecosystem hydrology research, and an important way to study ecosystem water conservation function and water resource utilization. After natural rainfall falls through the vegetation canopy, part of it is transformed into surface runoff, and part of it infiltrates into the soil. Sklash and Farvolden used isotope tracer technology in 1979 to find that most of the water in rivers comes from soil infiltration, and rainfall The resulting runoff will infiltrate through the soil, and even if there is no surface runoff, the rainfall will eventually collect into the river through soil infiltration. Therefore, it is of great significance to use effective means to observe soil infiltration (combined with surface runoff obser...
