Analysis of Spatio-temporal Evolution Characteristics of Cities, Towns and Villages' Land Use in Karst Mountainous Areas:Taking Qixingguan District as an Example
This research takes Qixingguan district as an example to analyze the spatio-temporal evolution characteristics of cities, towns and villages' land use in karst mountainous areas using methods such as GIS spatial analysis, kernel density and annual change rate. The results show that the cities, towns and villages' land use in Qixingguan district has a large scale evolution with significant temporal and spatial differences, among which the city land use and the central urban area and its eastern region have the most dramat-ic evolution; The spatio-temporal evolution of cities, towns and villages' land use in Qixingguan district has strong spatial autocorrela-tion and belongs to strong agglomeration distribution pattern, the hot spots of evolution show distinct direction of industry and develop-ment zone construction while the cold spots show obvious direction of physical geography environment. The present study provides sci-entific support and decision-making basis for urban-rural spatial reconstruction and territorial spatial planning of karst mountainous ar-ea.
