基于GIS的渭南市传统村落分布特征及影响因素研究

Study on Distribution Characteristics and Influencing Factors of Traditional Villages in Weinan City Based on GIS

文章通过对陕西省渭南市33处国家级传统村落的地理位置进行定位,结合GIS10.7对渭南地区的高程、河流水系、坡向的自然因素和经济发展水平等社会因素进行空间叠加分析。研究发现:渭南市国家级传统村落较高分布密度的区域分别位于县级韩城市和合阳县,在其余空间则分布较为分散;海拔250~750 m处传统村落分布最多,共有28个;与河湖水系之间的距离是传统村落选址中需要考虑的重要因素,尤其在涺水河、徐水沟等支流下游传统村落分布多达9个;向阳性明显是渭南传统村落的一个重要特征,向阳村落合计占全部村落的39.4%。

Based on the geographical location of 33 national traditional villages in Weinan City, Shaanxi Province, spatial superposition analysis of social factors such as elevation, river system, slope and economic development level, etc. in Weinan region is carried out in combination with GIS10.7. The results show that the areas with higher distribution density of national traditional villages in Weinan city are located in Hancheng city and Heyang County,while the other areas are scattered villages. Most of the traditional villages are located at 250-750m above sea level, with a total of 28villages. The distance from river and lake systems is an important factor to be considered in the site selection of traditional villages,especially in the lower reaches of Jushuihe River, Xushuigou and other tributaries, which are as many as 9 traditional villages. Positive is obviously an important characteristics of traditional villages in Weinan, and positive villages account for 39.4% of all the villages.
