Special tourism transportation is common in scenic area of different themes. For agricultural eco-scenic area, the road design has to consider the theme of the scenic area, thus animal power is a favorable transportation choice, it refl ects agricultural ecological characteristics and also takes production needs into consideration. This paper analyzed road design characteristics of agricultural eco-scenic area, and proposed the transportation model dominated by animal power and considering farming production, so as to meet the standards of "rural road" in agricultural eco-scenic area and comply with the style of agricultural tourism, and satisfy the visitors.展开更多
