Study on Road Characteristics in Watershed of Central Sichuan Hilly Areas
According to the field investigation data of roads in watershed of Iinshan Village, Yanting County in central Sichuan hilly areas, the distribution rules of roads in the watershed were studied by GIS spatial analysis. As indicated by the results, the roads in Iinshan watershed can be graded into four levels, including main road, field road, production road and branch road; the higher the level, the less the total length of roads, the total length is linearly correlated with the level of roads. The road network system and water system share some similarity in their structure and distribution rules; the distribution of different levels of road is influenced by topography and human activities; there is a linear regression relationship between the climbing road slope and terrain, and the distribution of secondary roads is controlled by the main road.
