摘　　要：基于可见光红外成像辐射(visible infrared imaging radiometer suite,VIIRS)年度夜光遥感数据,分别对贵阳都市圈内的夜光遥感总量、建成区面积及重心位置变化进行了研究。研究结果显示,在2012—2021年期间,贵阳都市圈的夜光总量规模和建成区面积都有了一定的增长,其中以贵阳市区域的增长幅度最大,和其他区域进一步拉大了差距;同时,区域内的经济活动空间格局呈“东北—西南”分布,重心点位于贵阳市辖区附近,并逐渐向南方向移动。Based on the annual nighttime light remote sensing data of visible infrared imaging radiometer suite(VIIRS),this paper studies the total amount of nighttime light remote sensing,the area of built-up area and the position of gravity center in Guiyang metropolitan area.The results show that from 2012 to 2021,the nighttime light amount scale and built-up area of the metropolitan area have increased to a certain extent,among which Guiyang has the largest growth rate,further widening the gap with other regions;at the same time,the spatial pattern of economic activities in the region is in the"northeast southwest"direction,and the center of gravity is located near Guiyang city and moves towards south.
