摘 要:新疆维吾尔自治区(以下简称“新疆”)作为中国西部战略屏障和向西开放的重要窗口,评估其城市化发展状况对于全国改革发展大局和“一带一路”倡议具有重要意义。相较于传统研究,夜间灯光遥感已被证明能够对人类活动强度和地区综合发展水平进行更客观、空间尺度更灵活、覆盖范围更广的监测。因此,本文利用2000年—2020年长时序夜间灯光遥感数据,采用标准差椭圆、时间序列分解以及夜间灯光发展指数等方法,从空间格局与时序演化上综合分析了21世纪以来新疆城市化进程。结果显示,2000年—2020年新疆城市化发展整体呈现向西南方向扩张的趋势,南疆地区发展速度强劲;21世纪以来新疆城市化演化过程可分为缓慢发展期(2007年之前)、波动增长期(2008年—2014年)和加速上升期(2015年之后)3个阶段;新疆城镇地区及大部分地市的社会发展愈趋均衡,而乡村地区仍处于快速发展的差异化阶段。总体而言,21世纪以来新疆城市化进程处于快速且均衡发展的状态。Given that Xinjiang Uygur Autonomous Region is a strategic barrier and an important platform of opening up to the western region,assessing its urbanization is critical to promote the national reform strategy and the Belt and Road Initiative.Compared with traditional method,nighttime light(NTL)remote sensing has been proved to be able to monitor human activity intensity and regional comprehensive development level in a more objective,flexible spatial scale and wider coverage.NTL remote sensing data has been able to analyze the urbanization evolution process and the level of social and economic development,but it is still necessary to expand and enrich the breadth and depth of research,especially to explore its spatial pattern and long-term evolution process,so as to more comprehensively understand the urbanization process and social development balance in Xinjiang.This paper comprehensively analyzes and discusses the evolution process of NTL in Xinjiang since the 21st century from three dimensions:time change trend,spatial distribution pattern and social development equilibrium,using NTL remote sensing data of long time series from 2000 to 2020,time series decomposition,spatial standard deviation ellipse and Night Light Development Index(NLDI).(1)From 2000 to 2020,the total amount of NTL in all regions of Xinjiang Uygur Autonomous Region increased to varying degrees.In terms of spatial pattern,urbanization in northern and eastern Xinjiang developed steadily,while rapid development in southern Xinjiang.The planning and construction of transportation lines is one of the important driving forces for the spatial expansion of urbanization in Xinjiang.(2)In the past 20 years,the total amount of NTL in Xinjiang has increased by 5.30 times,and the growth trend is accelerating.The NTL intensity in rural areas of Xinjiang increased by 7.60 times,which was larger than that in urban areas(4.10 times).The process of urbanization in Xinjiang can be divided into three stages:slow development(before 2007),volatile growth(from 200
