低山丘陵区生态农业旅游景观的效果分析

在丘陵地区城乡结合带,“生态农业旅游”景观应按坡度和等高线布置。形成坡顶水保林木带,坡上桃树带,坡中枇杷带,坡下特种瓜果带,坡底特色水域带的“垂直生态景观模式”。试验区的道路系统依地形贯穿全园。“农家乐”型生态农业旅游散布试验区内。试验区形成了良好的生态植被,生物多样性得到了恢复和发展。垂直景观林带有助于降低气温和土温,减少土温日变幅,增加空气相对湿度。果园自然生草、种植牧草后有增加空气相对温度、降低温度、减少温度变幅和防止水土流失的效果。优美的景观环境在发挥了生态效益的同时,也产生了良好的经济效益和社会效益。图2,表6,参15。

Landscape efficiency of eco-agricultural tourism in the hilly area

In the suburbs of hilly area, the landscape of eco-agricultural tourism should be designed according to the degrees of Slope and Contour Line: in the top land, trees were planted to form a water-conserving forest; in the upper section of the slope land, peach trees were planted; in the middle section, loquats trees were planted; in the lower section, special species of fruit trees, melons and vegetables were planted; the bottom fields were characterized with water area.Convenient traffic system was designed according to the land terrain.The "Fanner-family-entertainment" featured the eco-agricultural tourism.Vegetation and biodiversity returned and developed in the experimental area.The vertical agricultural landscape helped to lower the air and soil temperature in decrease the temperature changes in a day, and increase the air temperature relatively.Wildly growing-grass and man-planting herbage can increase relative air humidity, decrease the temperature, lower the changes of temperature in a day and conserve water and soil. Beautiful landscape brought in considerably social and economical benefits while it was playing an important role in ecology.
