Water and soil conservation ecological management system for erosion badland

Abstract

The invention discloses a water and soil conservation ecological management system for an erosion badland. The water and soil conservation ecological management system comprises a slope crest and a terrace arranged along a contour line, wherein a water and soil conservation forest used for controlling water and soil loss is arranged on the slope crest; water and soil conservation arbors are planted in the water and soil conservation forest; the terrace comprises a terrace wall and a terrace surface; a first planting area is arranged on the terrace surface; and economic plants are planted in the first planting area. Generally, the water and nutrient conditions of the slope crest of the erosion badland are poor; the water and soil conservation forest is planted on the slope crest of the erosion badland; rainfall runoff is intercepted; soil infiltration is increased; the water content of soil is increased; secondary distribution of the rainfall runoff is achieved; the utilization rate ofwater resources is increased; meanwhile, the coverage rate of vegetation can be increased; barren mountains are greened; the roughness of an underlying surface is increased; the runoff speed is reduced; the flow rate of surface runoff is reduced; the scouring capacity of the runoff is weakened; thus, the water sources are conserved, and the water and soil loss is reduced; and the first planting area is arranged on the terrace surface, and the economic crops are planted for greening and also can be utilized for increasing the income and recovering the cost.

Description

technical field [0001] The invention relates to the technical field of ecological environment management and the field of water and soil conservation, in particular to an ecological management system for soil and water conservation in eroded and bad land. Background technique [0002] Soil erosion degrades land, reduces productivity, and causes deterioration of the ecological environment, causing serious obstacles to agricultural production. The subtropical and tropical areas south of the Yangtze River Basin in my country have formed the southern red soil erosion area due to the combined effects of climate, biological conditions, geological topography and landform, plants, soil and many other factors. Over the years, due to the destruction of natural and human factors, the red soil area has become one of the areas with the widest range and highest degree of soil erosion in my country. The severity is second only to the Loess Plateau. The environment is deteriorating day by d...

Problems solved by technology

However, due to serious soil erosion, harsh environment, poor soil and other factors, erosion and poor land are extremely unfavorable for the survival and growth of plants.

Conventional soil and water conservation grass species are mostly used in the traditional treatment of bad land. Although they can exert good control effects in a short period of time, because the soil of the eroded bad land is too barren, it is often difficult to maintain it for a long time before it degrades and even reappears. become a bad place

[0004] Secondly, a series of engineering practices have been carried out in related fields, such as building ecological grass ditches on slopes, or afforestation and grass planting on bare slopes. Systematic design and comprehensive treatment of "surface-slope bottom", organically combine "mountain management" and "water management", and organically combine soil and water conservation with ecological agriculture
