Description

Loess slope collection rain afforestation slope protection structure Technical Field The utility model relates to the technical field of slope greening, in particular to a loess slope rain collecting greening slope protection structure. Background The loess hilly area is used as an ecological sensitive zone with most active water and soil loss worldwide, and the special coupling effect of the geological structure and the climate conditions deeply aggravates the water and soil loss risk. The fourth-period aeolian loess widely distributed in the area forms a fragile matrix with low shear strength and easy disintegration when meeting water due to the vertical crack development and loose porous structural defects, and has obvious disintegration and slippage characteristics under the combined erosion of gravity and water power. The long-term weathering soil forming process shapes the barren soil environment, is characterized by extremely deficient organic matters, loose aggregate structure, weak water holding capacity and the like, and obviously weakens the erosion resistance of the soil. The influence of typical continental monsoon climate is overlapped, seasonal precipitation is highly concentrated and is frequently generated in short duration of storm, so that dynamic unbalance of a water-soil system is caused, severe surface runoff and lamellar erosion processes are induced, and an ultra-high strength erosion pattern mainly comprising lamellar erosion and trench erosion is formed. Of particular concern is the continued hydraulic erosion that exacerbates soil desertification and water regulation degradation by stripping off surface fines, making vegetation reconstruction a "erosion energy-land decay-ecological retardation" chain reaction dilemma. The current engineering treatment system obtains staged effects through terraced fields soil preparation and sand blocking water storage engineering, but is limited by engineering geological characteristics of loess foundation softening collapse when meeting water and ecological threshold constraint of vegetation community water bearing capacity under drought stress, a systematic short plate still exists in the traditional treatment mode when coping with sudden heavy rainfall, and a comprehensive treatment paradigm combining soil and water process mutual feedback regulation and ecological engineering toughness improvement is needed to be constructed.
