Research Progress on Ecological Contol Measures of Sloping Orchards in the Three Gorges Reservoir Area

In order to provide reference for the ecological construction of sloping orchards in Three Gorges Reservoir area, relevant literatures about sloping orchards management and vegetation restoration were extensively reviewed, and the main ecological control measures and the eco-economic benefits were summarized. At present, there were four main measures to control soil erosion in sloping orchard including slope to terrace, plant hedge, tree-crop intercropping and mulching methods between agriculture and forestry, and the benefits were manifested in the following 4 aspects: controlling soil erosion, reducing nutrient loss, increasing soil fertility and increasing economic value. The soil and water conservation function of changing slope to terrace was remarkable, and the combination of plant hedge, covering technology and intercropping between agriculture and forestry had higher practical values and economic benefits. In the ecological treatment and vegetation restoration of sloping orchards in the reservoir area, relative factors such as topography, slope, climate, local social and economic development level and labor force status should be considered comprehensively. It would be more efficient to control soil and water loss of sloping orchards by combing engineering means with vegetation measures, and give full play to the eco-economic benefits of shrub and grass plants such as plant hedge, forage grass and crop.
