嘉陵江流域坡耕地“生态农业旅游”垂直景观模式

THE MODEL OF ECO-AGRICULTURAL TOURISM IN THE SLOPE LAND ALONG THE JIALING RIVER CATCHMENT

从治理水土流失角度出发,提出了坡耕地“生态农业旅游”技术与示范。其垂直生态景观模式按坡度和等高线布置:在坡度大于25°的山坡顶形成水保林木区,坡上15°～25°的陡坡种植桃树,坡中5°～15°的斜坡种植枇杷,坡下小于5°的缓坡地带种植特种水果、瓜类及蔬菜,坡底形成“稻—鱼”和“藕—鱼”特色水域区。道路系统设计为环山而下的水泥主路、观景石板干路、埂边地界小路三级,道路两侧实施还林还草。“农家乐”型旅游接待自然分布在试验区内,同时在坡上建立旅游“一条街”、坡底试验旅游产业化经营。果园内实施多熟作物覆盖、间种套种。垂直生态景观产生了独特而丰富的景观效果,并具有较好的生态功能、经济功能和社会功能。

To control water and soil loss, the technology and model for eco-agricultural tourism in the slope land of the hilly land were discussed. The model of vertical eco-landscape was designed according to the slope and contour line: in the top land over 25 °, trees were planted to form a water-conserving forest; in the slope land between 15° and 25°, peach trees were planted; between 5° and 15°, loquats trees were planted; less than 5 °, special species of fruit trees, melons and vegetables were planted; the bottom field was characterized with water area of “rice and fish”, “lotus and fish”. Road system is consisted of concrete road running down the hills, stone pass-way going among the landscapes, low banks stretching among the fields. At both sides of the pathways, grasses and trees were planted. “Farmer-family-entertainment” eco-agricultural tourism was distributed in the experimental area; a tourism-street was built on the slope land; and eco-agricultural tourism industrialization was managed in the bottom fields. Inter-planting models were designed with various species of crops ripening at different times. Vertical eco-landscapes brought in a special and abundant landscape efficiency , and functioned ecologically, economically and socially.
