嘉陵江流域坡耕地“生态农业旅游”垂直景观模式

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。

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

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.
