公路建设可持续发展与土地利用问题及其对策

为从理论上探索公路建设可持续发展路径,运用系统分析法及文献资料法分析了中国公路占地的历史与现状特征,并将其与国外对比。分析认为,当前中国公路占地特点是“一大、三低”,即公路建设占用土地面积大,土地利用率低、综合乘载能力低、整体产出率低;从公路建设可持续发展与土地利用的互动机理出发,提出了处理公路建设和土地保护关系的基本原则;公路建设是包含规划、选线、建设、通行管理等多环节的系统工程,并给出了上述各环节的节地技术标准和理顺相关利益关系人的制度性建议。

Problems from land use and sustainable development in highway construction and strategy

In order to explore, theoretically, the developing path in the sustainable development of highway construction, the paper, with the help of system analysis and documental data, examines the historical and current characteristics of land use due to highway construction. The analysis shows that this characteristics shows itself as being great in the land use and low in service efficiency, comprehensive capacity and output efficiency as compared with those in other countries. Starting from the interactive mechanism between land use and sustainable development of highway construction, the authors put forward the basic principle of the relationship between highway construction and land protection, including highway planning, route selection, construction work and service management, and finally propose the suggestions for the technical standards of land use saving, and human benefits for the above factors. The conclusion of the study is that highway construction is a system engineering which contains multi-link and multistage. Land use saving is very important in network planning, route selection, road construction and management and so on. These countermeasures can be effectively reduce the current pressure on land requisition of highway construction.
