基于环境可供性的骑行风景道规划设计研究 ——以昆明滇池骑行线路为例

运用环境可供性理论探讨骑行风景道物理环境及其使用者行为之间的相互关系，以昆明滇池骑行线路为例，通过参与式观察及深度访谈获取环境可供性的实现和需求情况，对可供性的类目特征、时空分布及可供性实现的影响因素进行分析。发现骑行风景道环境可供性在类型上主要包括消费、游憩、应急、运动4个大类；可供性空间分布与既有兴趣点高度邻近，时间分布基本与骑行者行为的时间特征相匹配；可供性实现的影响因素分为路内环境、路外环境、气候环境三方面，包括交通组织、路面材质、景观质量、天气类型等内容。根据分析结果，总结了骑行风景道规划设计策略，讨论了风景道骑行行为背景下可供性相互关系的多中心网络，提出通过网络中关键节点的识别来指导风景道建设。

Planning and Design of Scenic Bikeway Basedon Environmental Affordances: A Case Study ofKunming Dianchi Lake Cycling Route

This study focuses on the interaction between physicalenvironment and users'' behaviors in the context of scenic bikewaysthrough the perspective of Environmental Affordances theory. Theresearch adopts participatory observation and in-depth interview toexamine the demand and actualization of environmental affordances.Acquiring materials are used to analyze the environmentalaffordances'' taxonomy, time-space distribution and actualizationfactors. The results show: 1) consumptive, recreational, incidentaland sportive affordances constitute the 4 fundamental types ofenvironmental affordances, 2) the spatial distribution of environmentalaffordances shows a pattern of neighboring the Points of Interestalong the road, the temporal characters generally match with cyclists''behavioral timetable, and 3) factors that affect the actualizationprocess are basically relate to road itself, roadside environment andclimatic conditions, including the organization of transportation,materials of road surface, landscape quality, weather types, etc.According to these results, the authors summerize the planningand design strategies for scenic bikeways, discuss the multicentricnetwork of interrelation between different environmental affordances,and propose to identify the key nodes of this network gives guidancefor building better scenic bikeways.
