山地城市骑行绿道选线适宜性评价研究——以云南省普洱市为例

Suitably Evaluation of Route Selection for Cycling Greenway in Mountainous Cities——A Case Study of Pu′er City in Yunnan

以云南省典型山地城市普洱市为例,通过问卷调查及访谈、实地调查、专家咨询等方法,筛选出山地城市骑行绿道选线影响因子,运用层次分析法(AHP)构建适宜性评价模型,对普洱市思茅区骑行绿道适宜建设区域进行评价。结果表明,山地城市骑行绿道选线除强制考虑地质灾害和空间管制因素外,主要受自然环境基底、景观资源、交通环境、使用需求的影响,其中自然环境基底影响最大,最适宜区域分布在海拔600~1200 m、坡度0~8°地形较平坦的城镇及其周边;适宜区及基本适宜区为海拔900~1500 m、坡度0~20°区域;不适宜区域为海拔高于1700 m、坡度大于20°区域。

The influence factors of route selection for cycling greenwayin mountainous cities wereselected by questionnaire survey,interview,field survey and expert consultation,andthe suitability evaluation model was constructed by analytic hierarchy process(AHP)to evaluate the suitable construction area of cycling greenway in Simao District of Pu′er City,a typical mountainous city in Yunnan Province.The results showed that,besides forcibly geological hazards and spatial regulation,the route selection for cycling greenway in mountainous cities was mainly affected by natural environment base,landscape resources,traffic environment and use demand,and the natural environment base had the greatest influences;the most suitable area was distributed in the towns and their surroundings with flat terrain between 600~1200 m above sea level and 0~8°slope;thesuitable areas and sub-suitable areas were areas with an altitude of 900~1500 m and a slope of 0~20°;theinappropriate areas were areas with altitude higher than 1700 m and gradient higher than 20°.
