Ecological protection slope
ActiveCN110714471ANot easy to loseDrain resistanceCoastlines protectionExcavationsVegetationEnvironmental resource management
The invention discloses an ecological protection slope and relates to the technical field of slope protection. The ecological protection slope solves the problem that at the early stage of existing vegetation protection, the water and soil loss occurs easily. According to the key points of the technical scheme, the ecological protection slope comprises a slope body, a sand stone layer, a pluralityof straw bricks and straw fixing columns. The straw bricks protect the soil at the early stage of slope protection, and protect vegetation in through holes, thus the soil is not lost easily, as the vegetation grows, the root system of the vegetation becomes developed, the effect of resisting the water and soil loss can be achieved, moreover, straw decays into fertilizer gradually, growth of the vegetation is accelerated, plant seeds buried into the straw bricks in advance also grow into plants after the straw decays, thus the vegetation also grows on the straw bricks, at the moment, the full-grown vegetation protects the vegetation germinating on the straw bricks, after the vegetation grows fully, by means of the root system of the plants, the effect of slope protection is achieved, and after the straw bricks decay, the growing space of the vegetation is not occupied.
