太行山东麓土地利用格局时空变化分析
Spatio-Temporal Change of Land Use Pattern at the Eastern Foot of Taihang Mountains

土地是社会经济活动的基石，研究土地利用时空变化有利于优化区域发展格局，是实现土地资源可持续发展的有效手段。本文以太行山东麓为研究对象，采用土地利用动态度、综合强度、转移矩阵以及图谱分析的方法综合分析了该区域的土地利用变化情况。研究结果表明：1) 研究区在2个研究周期内土地利用综合动态度从0.44%下降为0.08%，建设用地的年变化率从11.01%下降至0.86%；2) 2000~2020年间研究区有12,691 km2的土地面积发生了动态转移变化，占比研究区总面积的34.26%，各类型土地间的相互转化十分剧烈；3) 涿鹿县、涞水县、顺平县、武安市、唐县、信都区在20年间发生了土地利用强度等级的动态变化，其余地区的土地利用强度未发生较大的变动；4) 从土地利用变化图谱模式分析，稳定型图谱(AAA)面积占比48.47%，持续变化型图谱(ABC)面积占比4.6%，其余图谱模式的面积占比差异不大。研究结果可为太行山东麓27个区县提升土地资源的空间布局和实现土地利用科学化的政策管理提供参照。
Land is the cornerstone of social and economic activities. Studying the spatio-temporal change of land use is beneficial to optimize the regional development pattern, and is an effective means to re-alize the sustainable development of land resources. Taking the eastern foot of Taihang Mountain as the research object, this paper comprehensively analyzes the land use change in this region by means of land use dynamic attitude, comprehensive intensity, transfer matrix and TuPu analysis. The results showed that: 1) the comprehensive dynamic attitude of land use in the study area de-creased from 0.44% to 0.08%, and the annual change rate of construction land decreased from 11.01% to 0.86% during the two research periods. 2) From 2000 to 2020, 12,691 km2 of land area in the study area has undergone dynamic transfer change, accounting for 34.26% of the total area of the study area, and the mutual transformation among different types of land is very intense. 3) The dynamic changes of land use intensity in Zhuolu County, Laishui County, Shunping County, Wu’an County, Tang County and Xindu District have occurred in recent 20 years, while the remaining areas have not changed greatly. 4) From the analysis of land use change TuPu patterns, the area of stable TuPu (AAA) accounted for 48.47%, that of continuous change TuPu (ABC) accounted for 4.6%, and there was no significant difference in the area proportion of other TuPu patterns. The results can provide reference for improving the spatial distribution of land resources and realizing the scien-tific policy management of land use in 27 districts and counties at the eastern foot of Taihang Mountain.
