基于分类分级管控的绿道综合安全风险评估体系建构

随着我国绿道建设的大量兴建和投入使用,绿道的综合安全风险问题也越来越引起关注。基于详细的现场调查,通过全面梳理绿道安全问题及其影响因素,辨识绿道安全风险问题,提出基于绿道安全风险的分级分类进行管控的总体思路,并借鉴自然灾害风险评估与交通安全风险评估理论,构建绿道自然环境、设施环境、使用环境三位一体的风险量化评估框架,明确不同类型风险的评估方法。最后,以深圳市为例,运用该风险评估体系对全市绿道网进行综合安全风险评估,并提出了相应的风险管控策略。

Construction of Integrated Risk Assessment System for Greenways Based on Categorical and Hierarchical Control

With massive construction and use of greenways in China,the issue of safety risks has attracted more and more attention.Based on detailed on-site investigation and lessons from natural disaster risk assessment and traffic safety management,this paper comprehensively analyzes greenway safety problems and their influencing factors,identifies greenway risk issues,proposes the idea of risk management based on risk classification.In reference to risk assessment theory,the paper constructs a three-in-one quantitative risk assessment framework for greenways in terms of natural environment,facility environment,and use environment,and clarifies the assessment methods for different types of risks.Finally,the paper applies the risk assessment system to Shenzhen's greenway network and proposes a corresponding risk management strategy.
