新疆公路自然区划探讨

新疆自然条件复杂,地貌类型多样,水、热地带性差异明显,公路建设遇到的问题较多。在广泛收集资料和野外调查基础上,利用GIS技术进行公路自然区划。通过区域自然环境和公路分布特点,与公路一、二级自然区划问题分析,提出异同性、地方性和实用性等区划原则,采用自上而下细分、自下而上合并和GIS制图的方法,进行公路三级区域划分,结果是将新疆公路自然区域划分为20区及7个副区。各区公路建设的自然条件不同。鉴于自然条件复杂性及公路建设问题多样性,建议利用三级区划结果进一步划分公路建设工程的自然条件类型,使区划成果应用价值得到进一步提高。

Physical-geographical regionalization of highway in Xinjiang

The natural conditions in Xinjiang are very complex.iandforms are various,water and heat are zonally different,so there are a lot of problems in building highway.Based on the extensive collection of information and field survey,this paper advanced a new way: divided the region of highway with the help of GIS.And by analyzing the regional characteristics of the natural environment and the distribution of highway,and the problem of the first class and the second class of geographical regionalization of highway,this paper brings forward the regional principles of similarities and differences,parochial and practicability,uses the methods of up-to-down subdivision,combination down-to-up and the mapping technology of GIS,divides Xinjiang into twenty zones and seven assistant zones.Eventually,because of the complex natural conditions and the variety of the highway construction,the paper suggests to use the result of the third regionalization to conduct subdivision in order to improve the value of the regionalization.
