Description

Loess hilly area terraced fields facility with rainwater is collected and is utilized function Technical Field The invention relates to the technical field of terraces, in particular to loess hilly area terraces facilities with rainwater collecting and utilizing functions. Background Loess hilly area terraced fields are used as important water and soil conservation engineering, play a remarkable role in the aspect of gentle slope cultivation and reducing soil erosion, but the rainwater recycling capability of the terraced fields still has obvious short plates. The terrains in the area are broken, the soil layer is deep, the traditional terraced fields are built by depending on natural slopes, the fields are narrow, and the fields are short, so that natural precipitation is difficult to effectively intercept. When precipitation is concentrated in rainy seasons, field runoffs quickly leak and cannot form effective storage, water demand critical periods of dry crops face water resource shortage contradictions, the existing rain collecting facilities mostly adopt simple reservoir structures, the site selection layout lacks systematicness, the structure design of the reservoir body does not fully consider the characteristics of regional high sand-containing runoffs, sediment accumulation phenomenon is common, the problem of blockage not only reduces the water storage volume, but also increases dredging maintenance cost, the sustainable operation of facilities is affected, technical faults exist in the cooperative design of a terrace system and the rain collecting facilities, a field runoff guide channel is imperfect, a sediment filtering mechanism is absent, and the rain collecting efficiency and the water quality guarantee are difficult to be compatible. Accordingly, it is necessary to provide loess hilly area terraced fields facilities having a rainwater collecting and utilizing function to solve the above-mentioned technical problems.
