Fig. 7: Relationship between traditional village distribution and variations in elevation, slope, and aspect.

This figure illustrates the relationship between the spatial distribution of traditional villages and topographic factors in the Suzhou region. The top row comprises three spatial maps: a elevation, b slope, and c aspect, with black dots marking the locations of traditional villages. The bottom row presents corresponding bar charts that quantify the number of villages within each interval. Map (a) employs a color gradient to represent elevation, ranging from 0 m (dark green) to 348 m (dark red). Map (b) uses a color gradient to represent slope, ranging from 0° (dark green) to 38° (dark red). Map (c) utilizes a color gradient to represent aspect, ranging from 0° (light blue) to 359.7° (dark red). The coordinate system is CGCS2000; base map data are sourced from Amap (Map Approval No.: GS (2024) 1158); the data set is provided by the Geospatial Data Cloud site, Computer Network Information Center, Chinese Academy of Sciences.
