Contour planting ecological management method and structural body thereof in medium-steep soil slope drawdown area

Abstract

The invention discloses a contour planting ecological management method and a structural body thereof in a medium-steep soil slope drawdown area. The method comprises the steps that the openness of a medium-steep soil slope ecological system and the basement stability of an earth surface are improved through an open-type reinforced concrete overall frame structure; the vegetation coverage and soil fertility of the drawdown area are improved through a contour planting plane surface greening technology and an earthwork standard room vertical greening technology; and biological diversity and stratification of landscapes in the drawdown area are improved through the arrangement of arbor-bush-grass-vine, bush-grass-vine and grass-vine plants suitable to drawdown areas in different high-level zones. The structural body is an open-type reinforced concrete overall frame and is composed of a plurality of structural single bodies. According to the contour planting ecological management method and the structural body thereof, a traditional concrete slope protection technology and a modern ecological slope protection technology are combined, and the contour planting plane surface greening technology and the earthwork standard room vertical greening technology are combined, so that biological control measures and engineering measures are in high unity, system stability and openness are in high unity, and the vegetation coverage and stratification of landscapes are in high unity.

Description

technical field [0001] The invention belongs to the field of ecological management, and in particular relates to a method for ecological management of contour planting in low-fluctuation areas of medium and steep soil slopes and a structure thereof. Background technique [0002] The "Three Gorges Follow-up Work Plan" passed in 2011 listed "construction and protection of the ecological environment in the reservoir area" as one of the six major goals, and how to develop appropriate ecological slope protection technology to solve the problem of ecological environment safety in the drawdown area has attracted much attention. And it has increasingly become the focus, difficulty and hot spot of the work. Therefore, the present invention takes the middle (15-25°) and steep (25-75°) soil slope fading areas where the eco-environmental problems of the Three Gorges Reservoir are the most prominent as the research object. The ecological management device for contour planting in the sin...
