摘　　要：为了使新疆公路自然区划的二级分区更加合理,以满足不同地域的公路建设需要,在新疆公路自然区划一、二级分区及适应性分析的基础上,按照新疆公路自然条件地貌构造的区域性、气候的纬向地带性、两大盆地的水平地带性和三大山地的垂直地带性等自然规律,提出了新疆公路三级区划考虑因素和区划标志,确定了新疆公路自然区划的三级分区。实践表明,新疆公路二级区划的6个二级区和两个副区可划分为27个三级区。In order to make the second level natural division for highway construction in Xinjiang province more rational, and to meet the requirements of highway construction in different areas, the adaptability of the first and second level natural divisions were analyzed. According to the regionality of physiognomy structure, climate latitude zonality, horizontal zonality in two basins, vertical zonality in three mountains, locality in small area of the rule for highway natural conditions in Xinjiang province, it is pointed out that to put forward the third level natural division for highway construction in Xinjiang province is very necessary. The influencing factors on the third level natural division were studied. Twenty seven third level areas in Xinjiang were set up on the basis of six second level areas and two ub-second level areas. 3 tabs, 10 refs.
