【摘要】 公路自然区划是研究自然环境对公路建设影响的产物 ,同时也是公路建设适应自然环境研究的结果。它可以为公路建设和环境生态保护提供科学依据。在综合分析我国公路建设对自然区划的要求和以往公路自然区划的适应性的基础上 ,探讨了新公路自然区划的原则、方法及分级指标的选取。得出新公路自然区划与以往公路自然区划的联系与区别 :新的自然区划的原则、方法同 1986年的《公路自然区划标准》大体上是相差不大的 ;新的自然区划的一、二级指标体系更注重了其实用性和应用性。更多还原

【Abstract】 The natural zoning for highways is the outcome that studies the influence of natural environment to the highway construction and the result that adapts the highway construction to natural environment. At the same time the natural zoning for highway may provide the scientific basis for the highway construction and environment ecology protection. On the basis of the request of highway construction to natural zoning for highways and the analysis of adaptability of the former natural zonng for highways, the principle,method and index system of a new natural zoning for highways are approached in the paper. In the end some conclusions are achieved that the principle, method of the new natural zoning for highways are similar as the “Standard of Climatic Zoning for Highway(1986)”; the indexes of the first and second classes of the new natural zoning for highways have paid more attention to their practicability and application.更多还原
