摘　　要：高速铁路建设给沿线景观生态、人群健康带来一定生态风险。基于压力-状态-响应模型构建了高速铁路建设生态风险评价指标体系,利用层次分析法确定各指标权重,以中心点三角白化权函数灰色评价方法为基础研究适用于高速铁路建设生态风险评价模型。将模型应用于京沪高速铁路某段,得到该段路域生态风险总体综合评价状态以及影响生态风险等级各对象评价状况。为管理决策者进行路域生态风险管理提供有效的依据。The construction of high-speed railway increases certain risks to the ecological environment and people healthy along the route. A study is made on ecological risks assessment model for high-speed railway construction based on the central point Triangle Whitening Weight Function gray assessment method. A high-speed railroad construction ecology risks assessment indicator system has been constructed according to the Pressure-Statc-Response（PSR）conceptual model and the analytic hierarchy process was used to determine that various targets weight in the model. Applies the model in one section of Beijing-Shanghai high-speed railroad, obtains ecological risks synthetic evaluation condition as well as the appraisal condition of various objects that influence ecology risks rank. Thus it helps the Beijing-Shanghai high-speed railway construction and management unit effectively to control the ecological risk and reduce the related loss.
