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。
Xinjiang has complex natural conditions and diverse topography types, with obvious differences in water and heat zones, with many problems encountered in highway construction. On the basis of extensive data collection and field investigation, GIS technology is used to carry out natural zoning of the highway. Based on the analysis of the regional natural environment and the distribution of roads, and the analysis of the primary and secondary natural division of roads, this paper puts forward the principles of zoning, such as diversity, locality and practicability, adopts top-down segmentation, bottom-up integration and GIS mapping Method, the division of highway three levels, the result is the natural area of Xinjiang Highway is divided into 20 districts and 7 vice district. The construction of roads in different districts has different natural conditions. In view of the complexity of natural conditions and the diversity of road construction issues, it is suggested that the classification of natural conditions of the highway construction project be further divided into three levels so that the application value of the regional achievements can be further improved.
