我国公路网规划环境影响评价

我国正处于公路交通飞速发展的历史阶段，公路建设在促进社会经济发展的同时也带来了显著的生态环境问题。由于目前建设项目环境影响评价的局限性日益突出，环评法以及相继出台的部门规章都要求从战略层次科学评估交通规划造成的潜在环境影响，促使交通战略的决策过程充分考虑环境因素。然而，我国交通战略环境评价起步较晚并较多关注于内容框架的研究，因此从宏观层面上对公路网规划的环境评价方法还有待完善和深入研究。以融合国际经验的湖北省骨架公路网规划战略环境评价为例，从规划分析、现状调查、指标体系、影响预测、制度分析和公众参与等方面，详细分析了我国公路网规划环境影响评价的技术路线确定、评价要点识别以及评价方法选取等内容，并从层次性和介入时机等方面讨论了我国交通战略环境评价存在的不足，为完善交通规划战略环境评价提供参考

STRATEGIC ENVIRONMENTAL ASSESSMENT OF ROAD NETWORK PLAN——A CASE IN HUBEI

China is experiencing a significant development of its road transport network，and this is causing ecological disruption and environmental issues.As for limitations of project environmental impact assessment，the enactment and implementation of 2003 EIA Law requires the assessment of environmental effects of transport plans and various provisions have been made to facilitate the implementation of transport strategic environmental assessment (SEA) and to integrate environmental considerations into transport decision making process.However，most existing researches were concerning with the context and framework of transport SEA，so methods for evaluating the impacts of road network that links urban areas are still on the way.Based on the case study from Hubei Province funded by the World Bank，the key issues and methodologies of road network plant SEA were demonstrated in this paper，including the plan analysis，baseline assessment，key issues identification，forecast，institutional analysis and public participation.Finally some discussions on the transport planning tiering and the appropriate linkage were provided to improve the implement of the transport SEA in China
