基于SP法的市民绿道游憩偏好实证研究——以四川省成都市为例

On Public Recreational Preference of Greenway Based on Stated-Preference Method——A Case Study of Chengdu

绿道作为绿色基础设施的重要组成部分,为市民创造了开放的线形绿色空间.基于叙述性偏好法(stated-preference method,SP法),从市民游憩需求侧角度出发,通过构造离散选择模型,对市民的绿道游憩偏好需求进行了量化性实证研究.研究结果表明,市民对于环境安静度、自然生态景观、沿线道路绿化、离家距离、公共交通接驳方式的关注度较高,而对于游憩健身设施、历史人文景观的关注程度较低;绿道离家距离越远其负效用增加越明显;绿道多样的交通接驳方式能显著增加绿道的正效用.最后,依据离散选择模型得到的拟合结果对未来成都绿道规划建设提出理性建议.

As an important part of green infrastructure,greenway creates an open green space for citizens.Based on the stated-preference(SP)method,studies have been done on the public recreational preference of greenway in Chengdu by constructing a discrete choice model to analyze the public recreational demand.The results show that the public pay more attention to the environment quietness,natural landscape,greening of roads,distance from home and public transportation connection,less attention to fitness facilities,historical and cultural landscape,and the further the greenway is from home,the more obvious the negative utility increases,and variety of traffic connections on the greenway can significantly increase the positive utility of the greenway.Finally,based on the results obtained from the discrete selection model,some advice has been offered to greenway planning of Chengdu in the future.
