重庆公路自然区划新方法研究

针对现行公路自然区划标准在重庆地区公路建设适用性上的不足,根据该地区实际情况,结合ArcG IS分析软件,提出新的公路自然区划总体研究方案;然后针对海拔高程、地形坡度、切割深度、岩土类型、植被情况、气候资源和地质灾害等要素对公路建设影响程度的不同,提出适于该地区自然地理环境的三级区划指标体系;最后建立由重庆公路自然单项分区、重庆公路自然专项区划和重庆公路自然区划构成的区划类型体系。研究考虑因素多,区划深度大,可更好地为该地区公路工程建设服务,在一定程度上推动现行区划标准的发展与完善。

Study on New Method of Natural Zoning of Highway in Chongqing

Facing the problem of current standards of natural zoning of highway in the feasibility of Chongqing highway construction,the new general research plan is brought forward according to the actual circumstance and the AcrGIS analyzing software;then aiming at the different impact on road construction influenced by elevation,gradient,surface incision density,rock-soil type,vegetation resources,climatic resources,geological hazards and so on,the three-level zoning guide line system suit for the natural and geogr...
