中国公路盐渍土的分区方案

在研究中国公路自然区划和盐渍土地区公路修筑技术的基础上，论述了中国盐渍土的分布和分布规律，分析了原有公路盐渍土分区的不足。根据新的资料和工程实践经验，考虑公路发展的需要，采用综合自然区划的一般原则和方法，紧紧围绕为公路工程服务的目的，提出了新的公路盐渍土分区方案。将中国盐渍土分布区划分为滨海盐渍土大区、东部半干旱-半湿润盐渍土大区、中部干旱盐渍土大区、西部强干旱盐渍土大区与特干盆地盐渍土大区5个大区，并给出了各大区内盐渍土的特点和修筑公路所面临问题的主要差别。对各大区内部亚区的划分也提出了方案和意见。

Highway-related dividing scheme of salty soil

Based on the investigation of China's geological division and highway construction technology in salty soil area,this paper briefly introduces China's geological distribution of salty soil area and the regular pattern of the distribution,analyzes the shortcomings of established division of salty soil.In the light of up to date sources and practical experiences,as well as the present situation of highway development,by the use of general regulation and way of comprehensive geological divistion,with the purpose of serving highway engineering,this paper puts forward a new dividing scheme of salty soil area related with highway construction,which divides the total salty soil area into five divisions and specifies respective distinctions and aspects related with highway construction.These five divisions are the Coastal Salty Soil Division,the Eastern Semiarid Salty Soil Division,the Central Arid Salty Soil Division,the Western Extra Arid Salty Soil Division and the Extreme Arid Basin Salty Soil Division.This paper also recommends the scheme regarding subdivisions of salty soil area in each division.1 figs,6 refs.
