摘要：
With the proposal and implementation of the Rural Revitalization Strategy, the relationship between urban and rural areas has entered a new period of integrated development. It is of great practical significance to clarify the evolution process and current characteristics of the typical regional urban-rural settlement scale system and explore its spatial reconstruction and optimization path for the realization of agricultural and rural modernization. Taking the Ugan-Kuqa River Delta Oasis (hereinafter referred to as "Weiku Oasis") on the northern margin of the Tarim Basin in Xinjiang as an example, this paper used land-use data from 2009 to 2018, GIS spatial analysis and rank-size rules to describe the characteristics of the urban-rural settlement scale system, and discussed the urban-rural settlement scale system in the study area according to the theoretical connotation of the multilevel goal of the rural revitalization spatial reconstruction mode and optimization path. The results showed that (1) in the process of the construction of the urban and rural system, the leading role of cities and towns was weak, the overall expansion of the urban-rural settlement scale was fast, the contrast between the urban and rural population and settlement growth was large, and the maladjustment of the rural man-land relationship was obvious. (2) The overall distribution of the urban and rural settlement scale obeyed the rank-size rule, the phenomenon of a "wagging tail" of sporadic settlements was increasing, the spatial disorder of expansion was obvious, and the spatial distribution of urban and rural settlements presented the characteristics of agglomeration; however, the spatial agglomeration trend toward the central town was not obvious. (3) The first measure of spatial reconstruction of the urban and rural settlement scale system was to renovate scattered patches. Three optimization targets were set for typical sample areas, and the path of spatial reconstruction was analyzed logically. Five kinds of renovation directions were proposed. Based on the multilevel goal of rural revitalization, it is of great practical significance to construct a spatial reconstruction scheme with land factor flow as the key variable to promote the structural optimization and functional coordination of the urban and rural settlement system in the Weiku Oasis and to realize rural revitalization. © 2022, Science Press.
