高速铁路可达性对区域、城市和车站层面土地使用的影响——基于研究综述的评价框架

The Impact of HSR Accessibility on Regional,Local and Station Level Land Use:An Evaluation Framework Based on Literature Review

相关理论和实证研究表明,高铁对于城市用地发展具有深远的影响,并会带来城市用地发展的不平衡。然而,用地变化能在多大程度上归因于可达性,结论差异性较大,尚没有定论。为了将现有聚焦于结论的文献综述转型为注重研究方法和变量,追溯3个空间层面的研究,分离可达性和其他要素,并分析在不同背景下实证研究结论差异的原因。目前大部分研究方法可以归纳为4类:情景比较、分组对照、回归模型和离散选择模型。同时,可达性指标包括定性分析、影响区划分、单个指标、综合指标和成组指标。最后,推荐采用基于实证的纵向研究,选取与研究目的相符的弹性指标。

Theoretical and empirical studies have found that high-speed rail(HSR)has profound impacts on urban land use development.Most studies revealed inequity development brought about by HSR.However,the consensus has not been reached concerning the extent to which the observed urban land use changes can be attributed to accessibility.To turn from current literature reviews focusing on conclusions to methodologies and variables,this paper traces different research approaches on three geographic scopes,separates the effects of accessibility from other factors and sheds light on the reason for controversial conclusions among case studies under specific backgrounds.To date,most studies addressing the relationship between HSR accessibility and land use fall into four categories of research methods:scenario comparison,group contrast,linear regression models,and discrete choice models,whilst accessibility indicators include descriptive analysis,influence zone,single index,integrated index and grouped indexes.Finally,a longitudinal study applying elastic evaluation indicators in accordance with research purpose is recommended.
