摘要
选取 2000 年、2010 年 Landat5 和 2020 年 Landsat8 遥感影像,进行土地监督分类并计算建成区面积,对2000-2020 年南阳市建成区扩张的时空特征进行探析.得到南阳市建成区扩张速度和扩展强度两个维度的时空特征,分析了影响南阳市建成区扩张时空特征的因素,包括政策因素、地形地势的影响、经济因素、交通等基础设施的建设等.
Abstract
The Landsat5 remote sensing images in 2000 and 2010,as well as the Landsat8 remote sensing image in 2020,were selected for land supervision classification,mapping,and calculation of the built-up area in Nanyang city.Subsequently,the spatial-temporal characteristics of the expansion of the built-up area from 2000 to 2020 were analyzed in two dimensions:expansion speed and expansion intensity.The spatial-temporal characteristics of the expansion of the built-up area in Nanyang City are obtained.The factors that influence the spatial-temporal characteristics of the expansion of the built-up area in Nanyang City include policy factors,the influence of terrain and elevation,economic factors,and the construction of transportation and other infrastructure.
