Taking Jinghe River Basin in the Loess geomorphological area and Guangnan County in the karst geomorphological area as the study area, the spatial distribution characteristics of urban and rural areas of different geomorphological types are analyzed. By using GIS and related statistical analysis software, this paper summarizes three basic urban and rural types: river channel type, plateau surface type, and loess terrace horizon prototype in the Loess Landscape Jinghe River Basin. It is known that most towns in the loess plateau gully area are in the Jinghe River Basin. According to the spatial distribution characteristics of urban and rural areas, the optimal layout based on the main structure of five districts, nine River corridors, and four plates is proposed. Using the DEM module of ArcGIS to divide the elevation and gradient of Guangnan County, we know that the density of urban and rural settlements in Guangnan County is low and the spatial distribution is dispersed, and the distribution of urban and rural settlements shows a strong elevation orientation. The distribution of urban and rural settlements has a normal distribution relationship with the elevation. The largest number of urban and rural settlements is between 2.1° and 25°. According to the present situation of settlement distribution, this paper puts forward some optimization strategies, such as appropriate settlement scale, settlement space development monitoring, and so on.

Este estudio analiza las características de distribución espacial de áreas urbanas y rurales de diferentes tipos geomorfológicos al tomar como área de estudio la cuenca del río Jinghe, en el área geomorfológica de Loess, y el condado de Guangnan, en el área geomorfológica kárstica. Mediante el uso de Sistemas de Información Geográfica y aplicaciones de análisis estadístico relacionado, este documento resume tres tipos básicos urbanos y rurales: tipo de canal de río, tipo de superficie de meseta y prototipo de horizonte de terraza de loess en la cuenca del río Jesshe. En esta cuenca se encuentran asentamientos humanos principalmente ubicados sobre depósitos de loess. De acuerdo con las características de distribución espacial de las áreas urbanas y rurales, este estudio propone un diseño óptimo basado en la estructura principal de cinco distritos, nueve corredores fluviales y cuatro placas. Al usar el módulo DEM de ArcGIS para dividir la elevación y el gradiente del condado de Guangnan se estableció que la densidad de los asentamientos urbanos y rurales en este condado es baja, la distribución espacial es dispersa y la distribución de los asentamientos urbanos y rurales muestra una fuerte orientación de elevación. La distribución de los asentamientos urbanos y rurales tiene una relación de distribución normal con la elevación. El mayor número de asentamientos urbanos y rurales está entre 2.1° y 25°. De acuerdo con la situación actual de la distribución de asentamientos, este documento presenta algunas estrategias de optimización, como la escala de asentamiento apropiada, el monitoreo del desarrollo del espacio de asentamiento, entre otros.
