Spatial Distribution Characteristics and Affecting Factors of Rural Residential Land in the Mountainous Area Based on Voronoi and Landscape Indices

Rural residential land spatial structure not only reflects the evolution trend of relationship between human and land, but also affects the regional economic development. Taking the typical mountainous landform Shennongjia district as the study area, Voronoi diagram and ecological landscape index were applied in this paper. The result revealed that the rural settlement distribution pattern presented agglomerative type in general and the spatial landscape pattern showed low fragmentation, scattered distribution and stable plaque. The main influence factors are the terrain, the river distribution, transportation. What’s more, the spatial layout of rural residential land is particularly affected by terrain and transportation. It offers theoretical support in renovation of the village residential area.
