摘要
乡村聚落用地的地域性分异规律是国土空间分类施治的科学依据。运用空间分析、景观格局指数、乡村位序-规模法则等方法,对比研究1990—2020年宁夏北部引黄灌区、中部干旱带和南部山区代表地市乡村聚落时空演化规律及影响因素。结果表明:(1)北部引黄灌区银川市乡村聚落用地空间结构呈高密度团状—宽带状—团状演变;中部干旱带吴忠市呈低密度分散—中密度散点状演变;南部山区固原市呈中密度团状嵌套分布。(2)不同地理分区乡村聚落用地均进行了整合,用地先以新生、扩张为主,侵占农业生产、草地生态空间,2005年后有补偿农业生产、生态空间的趋势。(3)北部引黄灌区和南部山区大规模聚落发育欠佳,小规模聚落需整合。宁夏不同地理分区乡村聚落演变规律共性与个性并存。
The geographical differentiation pattern of rural settlement land use is the scientific basis for the spatial classification and governance of the country.The spatial analysis,landscape pattern index,and the countryside order-scale rule were used to compare the spatial and temporal evolution patterns and influencing factors of rural settlements in the Northern Diversion Irrigation Area,Central Arid Zone and Southern Mountainous Area of Ningxia from 1990 to 2020.The results show that:(1)The spatial structure of rural settlements in the Northern Yellow Diversion Irrigation Area evolves in a high density cluster-wide banded-cluster pattern;the Central Arid Zone evolves in a low density dispersed-middle density scattered pattern;and the Southern Mountainous Area evolves in a medium density nested cluster pattern.(2)The land use has been integrated,firstly,the land use is mainly new and expanding,encroaching on agricultural production and grassland ecological space;after 2005,there is a tendency to compensate for agricultural production and ecological space.(3)Large scale settlements in the Northern Yellow Irrigation Area and Southern Mountainous Areas are poorly developed,and small scale settlements need to be integrated.The evolution pattern of rural settlements in different geographical zones of Ningxia has both commonalities and individualities.
