Research on Regional System Planning Method of Rural Habitat in Gully Regions of the Loess Plateau, under the Background of Rural Vitalization Strategy in China

Against the background of the Rural Vitalization Strategy in the gully regions of the Loess Plateau, large number of residents living in gullies move to tableland. On the one hand, this causes the disappearance of slope villages and gully villages; on the other hand, it increases ecological pressure on tableland, which was originally densely populated. The villages' locations, the developing conditions, and the ecological carrying capacity of the surrounding villages have influence on the development direction of these villages and regional system planning. Through comparative analysis of different analysis methods for determining ecological carrying capacity, this paper takes the limiting factor analysis method as the main method and improves it according to the local conditions. Through the analysis of maximum ecological carrying capacity, current carrying capacity, and current population, we can determine which villages have the potential to support more immigrants and which ones should be integrated with others to improve the human settlement environment. At the same time, villages are graded so that the present and future human settlements' environment can be further analyzed and predicted, which can be also adopted as an important guide for the local villages' relocation and combination. Finally, we select a representative region to prove the general applicability of our planning method in the Loess Plateau.
