Spatio-temporal evolution of rural settlements distribution pattern and its driving forces in the Yellow River Basin under the background of rural revitalization
Spatio-temporal evolution of rural settlements distribution pattern and its driving forces in the Yellow River Basin under the background of rural revitalization
The study uses land use data from 1980 to 2020 in the Yellow River Basin and employs landscape indices,kernel density estimation,land transfer matrix,and geodetector to analyze the spatio-temporal evolution and driving forces of rural settlements at the scale of urban agglomerations.The results show that:①The overall land use scale of rural settlements is expanding,mainly converted from dry land;The density of rural settlements in the urban agglomeration of the Central Plains changes mostly.With the exception of the Guanzhong Plain urban agglomeration,the shape of the rural settlements in the other six urban agglomerations became more regular.② The spatial distribution of rural settlements shows that"the southeast is agglomerated,and the west and north are scattered",showing a more intensive development trend,among which the urban agglomeration in the Central Plains changes mostly.③ Rural settlements are mainly distributed below 1 km above sea level and 2～5 km away from rivers,and their scale is inversely proportional to the distance from roads;Roads are the main factors affecting the distribution of settlements in Lanxi,Ningxia-Yanhuang,Guanzhong Plain and Shandong Peninsula urban agglomerations,while elevation is the main factor affecting the distribution of settlements in Hubao-Eyu,Jinzhong and Central Plains urban agglomerations.
