摘　　要：以西宁—海东都市圈为研究对象,基于2012—2022年VIIRS夜间灯光遥感影像数据,利用灯光信息统计、趋势分析和景观格局指数分析评价都市圈内城镇时空格局演变。结果表明:①在时间维度上研究区城镇建设和发展规模不断增强,一体化发展趋势明显;②在空间维度上研究区呈现明显的空间异质性,中心城区仍是主要的建设发展区,工业园区、清洁能源建设区成为新的增长极;③平均斑块面积标准差和周长面积分形维数呈V形变化,平均最近邻体距离不断缩小,说明研究区城镇差异性发展,聚集度不断提升。研究结果可为助力国土空间规划落实落地提供借鉴。Taking the Xining-Haidong Metropolitan Area as the research object,based on VIIRS nighttime light remote sensing image data from 2012 to 2022,we used the light information statistics,trend analysis,and landscape pattern index analysis to evaluate the evolution of urban spatial pattern within the metropolitan area.The results indicate that①temporally,the construction and development scale of towns within metropolitan area have continuously increased,demonstrating a clear trend towards integrated development.②Spatially,the development of metropolitan area exhibits significant spatial heterogeneity,with the central urban areas remaining the primary construction and development zones,while industrial parks and clean energy construction areas have emerged as new growth poles.③The standard deviation of average patch area and perimeter-area fractal dimension show a V-shaped change,while the average nearest neighbor distance continues to decrease,illustrating the differential development and agglomeration degree of towns within the metropolitan area being constantly improving.The research findings provide valuable references to support the implementation of territorial spatial planning.
