基于景观功能的山区旅游公路水土保持设计思路——以湖北神农架木鱼坪至兴山县昭君桥旅游公路为例

为了充分发挥山区旅游公路水土保持措施的景观功能,以湖北神农架木鱼坪至兴山县昭君桥旅游公路为例,从景观美化功能和景观协调功能2方面进行水土保持设计。景观美化功能方面,根据项目沿线的自然、人文和公路本身的特点,分为3类景观特色带、3个景观过渡带和8个景观特色点,并配置相应的水土保持措施。景观协调功能方面,依据沿线的具体情况,使用渐缩式（阶梯式）空心砖护面墙、上挡墙L形种植槽、路基外侧悬墙式植槽和木桩栅栏式挡墙等绿化技术,进行公路沿线的绿化和美化。

Thoughts of soil and water conservation design for tourism highway in mountain area based on the landscape function: A case study of the tourism highway from Muyuping in Shennongjia to Zhaojun Bridge in Xingshan County, Hubei Province

In order to give full play to the landscape function of soi and water conservtion measures of tourism highway in mountain area,we took the tourism highway from Muyuping in Shennongjia to Zhaojun Bridge in Xingshan County,Hubei Province as the example and collocated the soil and water conservation measures based on the optimization of landscape function and the coordination of landscape function. In terms of the optimization of landscape function,the highway was been divided into three landscape characteristic zones,three landscape transition zones and eight landscape characteristic spots according to the characteristics of natural,human culture conditions along the highway.At the same time,the soil and water conservtion measures were collocated in corresponding zone or spot.In terms of the landscape coordination function,the afforestation technology of ladder hollow brick facing wall,the L plant trough top retaining wall,the suspended type plant trough outer roadbed and the timber pile fence facing wall were used to landscape construction and greening along the highway.
