Description
Technical Field
The invention belongs to the technical field of detection devices, and particularly relates to a vegetation and litter water interception test device.
Background
Conservation of water resources refers to the measure of maintaining water resources. The purposes of controlling soil degradation and reducing water and soil loss can be achieved by recovering vegetation and building a water source conservation area generally.
The vegetation canopy and litter interception and water storage functions are one of the important factors influencing the water source conservation function of the grassland ecosystem. Research on the contribution of grass vegetation canopies and litter to the water conservation function is increasingly paid attention by scientists at the present stage. However, how to quickly simulate the effects of grass vegetation canopies and litter on trapping rainfall and conservation is one of the key technologies. In the past, a single plant soaking method is adopted, so that the difference of the composition and the structure of grassland vegetation communities is ignored, and the test result is larger finally; another common method is the trenching method, i.e. simulated precipitation of turf for the purpose of measurement, which is laborious and environmentally damaging. Therefore, based on the method, the technology explores a vegetation and litter water interception test device which is rapid, convenient, accurate and low in destructiveness.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a vegetation and litter water interception test device.
The vegetation and litter water interception test device is realized by the following steps that a base is arranged, a water collector is arranged at the upper end of the base, a water collection hole is formed in the middle of the water collector, and the lower end of the water collection hole is communicated with a welding funnel; the welding funnel is placed inside the base;
the outer wall of the water collector is embedded with a transparent toughened glass window, and the surface of the transparent toughened glass window is provided with a measuring scale.
Further, the base is welded and installed by adopting a frame structure, and the height of the base is 30 cm.
Further, the size of the water collector is as follows: 25cm × 25cm × 10 cm.
Further, the length of welding funnel is 15cm, the internal diameter of welding funnel is 2 cm.
Further, fixed teeth are arranged inside the water collector, and rubber sealing rings are integrally arranged at the edges of the fixed teeth; the size of the fixed teeth is as follows: 24.5 cm. times.24.5 cm. times.1 cm.
Further, the inner diameter of the water collecting hole is 2 mm.
The invention has the advantages and positive effects that:
firstly, the interception effect of tested grassland vegetation community components on rainfall and the storage effect of litter can be reflected, and the problem that the estimation result theory is larger because the previous research is only used for measuring several target plants of the vegetation community is solved;
secondly, rainfall interception amounts of different vegetation and litter thickness can be quantitatively simulated, and meanwhile rainfall retention amount of the litter can be measured, so that the storage capacity of the litter can be reasonably evaluated, and the interception capacity of vegetation rainfall of different thicknesses can be accurately measured;
thirdly, the labor is saved and the environment is not damaged.
