摘要
采用文献综述法分析三峡库区坡地果园治理和植被恢复相关研究成果,总结坡地果园生态治理的主要措施及其生态经济效益,为库区坡地果园生态建设提供参考。现有库区坡地果园水土流失治理的主要措施有坡改梯工程、植物绿篱、农林间作和覆盖措施,其生态经济效益体现在控制水土流失、减少养分流失、提高土壤肥力、增加经济价值等方面。坡改梯水土保持功能显著,而结合植物绿蓠、覆盖技术、农林间作等措施进行治理,具有更高的实用价值和经济效益。库区坡地果园的治理和植被恢复,应综合考虑地形、坡度、气候以及当地的社会经济发展水平与劳动力状况等因素,将工程措施和植物措施有效结合,充分发挥植物绿篱、生草和农作物等灌草植物的生态经济效益。
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.
