摘      要：Identifying the spatiotemporal evolution characteristics of rural settlements and their driving factors is of great significance to layout optimization of rural settlements,intensive and economical use of rural land,and preparation of land space *** on the mountain-plain transitional zone of Dujiangyan City,China,as the study area,this paper employs methods including landscape pattern index,kernel density estimation,average nearest neighbor index,and Geodetector to quantitatively analyze the spatiotemporal layout evolution characteristics of rural settlements and relevant driving factors in Dujiangyan City over the last *** four main findings are as ***,land use area of rural settlements and the quantity of patches in Dujiangyan exhibited synchronous changes during *** class area(CA)increased from 6161.43 to 7265.43 hm^(2),then declined to 7043.01 hm^(2),and the number of patches(NP)increased from 16543 to 26018,and then declined to ***,the maximum kernel density estimation values in the east and southeast of Dujiangyan City increased remarkably from 48.34 to 74.69 per hm^(2) during ***,the average nearest neighbor index of rural settlements continually decreased in the foregoing 10 years,indicating a higher concentration of rural ***,production and living conditions are the main driving factors of dynamic change in land use in rural settlements,while the impact of socio-economic factors is relatively *** others,the p-value of road accessibility is 0.057,and the impact p-value of land slope is 0.035.
