摘要
基于2013年、2018年、2021年Landsat 8 OLI数据,采用面向对象的随机森林方法进行土地利用分类。运用土地利用变化动态度和格网分析法,从整体和部分两个角度分析研究区土地利用的时空变化规律,探究行政区划调整对土地利用变化的影响。结果表明,(1)原济南市建设用地面积增速放缓(动态度从0.04下降到0.01),土地利用程度升高,且耕地面积增加(176.74平方千米)。(2)原莱芜市建设用地面积快速增加(176.74平方千米),土地利用程度提高较快。(3)本次行政区划调整,提高了原济南市土地集约利用程度,带动了原莱芜市的经济社会快速发展,优化了区域整体土地利用格局。
Based on Landsat 8 OLI data for 2013, 2018 and 2021,we used the object-oriented random forest method for land use classification, applied the land use change dynamic attitude and grid analysis methods to analyse the spatial and temporal land use change patterns of the study area from both the overall and partial perspectives, and explored the impact of administrative division adjustment on land use change. The results show that,(1) the growth rate of the former Jinan City’s construction land area slowed down(the dynamic attitude decreased from 0.04 to 0.01), the degree of land use increased, and the arable land area increased(176.74 km~2).(2) The area of construction land in the former Laiwu City increased rapidly(176.74 km~2), and the degree of land use increased more rapidly.(3) This administrative division adjustment has increased the degree of intensive land use in the former Jinan City, driven the rapid economic and social development of the former Laiwu City, and optimized the overall land use pattern of the region.
