低山丘陵区农村道路分布特点及其影响因素分析—以内蒙古四子王旗农耕区为例

Rural roads distribution characteristics in low mountain and hill regions and the impact factors- Taking the farming area of Siziwang County as an example

半干旱低山丘陵区的乡村道路在农村经济发展中起着重要作用,道路的布局直接影响道路的使用价值,合理的布局使交通运输顺畅,可减少道路遭受流水侵蚀,促进农村经济发展。文中以阴山北麓四子王旗的农耕区为研究对象,利用遥感图像,在ARCGIS软件下处理,结合实地调查,对研究区内道路的分布、道路分布的影响因素进行研究。研究表明:1)研究区道路分布与居民点和地形地貌特点及土地利用密切相关,研究区居民点分布表现出明显的集中性;2)由于地形和土地利用的特点,研究区的道路分布有沿谷型、放射状和格子状三种;3)沿谷型、放射状和格子状三种农村道路格局也间接反映了道路所在区域农业发展特点,它是人类与自然长期作用的结果。

The rural roads of low mountain and hill regions play an important role in the rural economic development in semi- arid areas. The layout of the roads directly affects the use value of the roads. The reasonable roads layout makes the transportation smooth,reduces the roads eroded by the running water,and promotes the rural economic development. This research took the agricultural area in Siziwang County as an example,by using remote sensing image,combined with the spots investigation,studied the roads distribution in the area,and the affection factors of the roads landscape. Results showed： 1） The roads distribution is closely related with residential areas,terrain and landscape characteristics and landuse. The distribution of residential areas shows obvious concentration. 2） For the reason of the characteristics of the terrain and land use,there are three kinds of the roads distributions in the area： valley- along type,radial type and grid type. The three kinds of roads pattern also indirectly reflects the agricultural development characteristics of the studying area; it was the result of long-term reaction of human to the nature.
