摘　　要：为有效推进风景道路网健康、可持续发展,针对风景道路网评价方法不完善、规划建设依据不充分等问题,从风景道路网的定义及内涵入手,基于路网布局规律,借助物理学、系统学等相关理论,提出了风景道路网耦合性的基本内涵与分析目标。遵循"作用机理与耦合关系-指标构建与阶段分析-问题诊断与目标明确-空间优化与系统提升"的总体思路,利用物理学中"耦合度"的概念,运用耦合性分析理论,对风景道路网及其子系统的发展水平及相互影响进行了分析评价。通过构建风景道路网耦合协调度模型,提出了风景道路网评价指标体系,并对风景道路网线路与节点系统进行了耦合性分析。根据耦合度评价结果,将耦合关系划分为"失调发展、濒临失调、基本协调和高度协调"4种状态。以河北草原天路风景道路网为例,通过耦合度评价指标构建及耦合性分析,对草原天路风景道路网所处的发展阶段、存在的突出问题进行了研究,根据耦合度评价结果分别对草原天路风景道线路和节点系统提出了优化提升措施。这些研究可为风景道路网结构优化和系统提升提供理论支撑和实证参考,对促进我国风景道路网建设具有重要意义。In order to effectively promote the healthy and sustainable development of scenic byway network,in view of the imperfect evaluation method of scenic byway network and the insufficient planning and construction basis,starting from the definition and connotation of the scenic byway network,the basic connotation and analysis objective of the coupling of the scenic byway network are proposed based on the layout of road network with the help of physics,systematology and other related theories.Following the general idea of"interaction mechanism and coupling relationship-indicator construction and stage analysis-problem diagnosis and objective definition-space optimization and system improvement",using the concept of"coupling degree"in physics and coupling analysis theory,the development level and mutual influence of scenic byway network and its subsystems are analyzed and evaluated.Through the construction of the coupling coordination degree model of scenic byway network,the evaluation indicator system of scenic byway network is proposed,and the coupling analysis of the route and node system of scenic byway network is carried out.According to the coupling degree evaluation result,the coupling relationships are divided into 4 states:maladjusted development,on the verge of maladjustment,basic coordination and high degree coordination.Taking the Grassland Tianlu Scenic Byway Network in Hebei Province for example,through the construction of coupling degree evaluation indicators and coupling analysis,the development stage and outstanding problems of the Network are studied.According to the evaluation result of the coupling degree,the optimization measures for the route and node system of the Grassland Tianlu Scenic Byway are proposed.These studies can provide theoretical support and empirical reference for the structural optimization and system improvement of scenic byway networks,and are of great significance for promoting the construction of the scenic road networks in China.
