摘要
山西省沿黄旅游公路走廊带大部分位于黄河阶地,配建生态绿道具备较好的工程条件及可使用性,但是受地形地物限制,仍存在部分长距离越岭路段,越岭段连续纵坡直接影响生态绿道能否很好地为使用者服务。在越岭段生态绿道与公路主线共幅布设的情形下,对旅游公路及生态绿道使用者市场予以细分,从使用者视角及难度分级定量化角度出发,通过与《公路路线设计规范》的相关规定对比分析,论证了生态绿道纵断面设计满足合规性后,可以较好地为使用者服务,从而为生态绿道纵断面设计提供借鉴及参考。
Most of the tourism highway corridors are located in the Yellow River terrace,with good conditions and applicability for ecological green passageways,but constrained by landform and terrain,there are some long road sections needing to cross mountains where the continuous longitudinal gradient directly affects the serviceability of ecological corridors.Under the conditions that the green corridor needs to be built together with the main route of highway in some road sections across mountains,the sources of users are analyzed in details,and from the perspectives of users and quantified grading of difficulty,and through comparisons with the related stipulations in the Specifications for Design of Highway Alignment,it is verified that after meeting the requirements of profile design for ecological green corridor,the users can be better benefited so as to provide reference and basis for design of profile for ecological green corridors.
