摘要
本文以肇州县2013年和2020年的Landsat8 OLI为主要数据源,在RS和GIS技术支持下,对肇州县土地利用数据进行处理,进行空间分析并探究其时空变化规律。结果表明:从土地利用现状图可知,肇州县以耕地为主,占据优势地位;从土地利用变化图谱分析中可知,草地和未利用地呈增加趋势,转移图谱以耕地→未利用地和耕地→草地为主,转移面积达到354.22 km^2;2013—2020年间,草地新增面积最大,主要源于耕地、林地及建筑用地的转入;总体来看,土地利用格局趋于稳定。通过构建土地利用变化时空图谱,丰富了LUCC时空分析研究体系,为今后的土地利用研究提供有效的方法。
Geo-information maps use simple language and graphics to express complex geographical phenomena,and provide an effective means for spatial analysis of land use.This article uses Landsat8 OLI in Zhaozhou County in 2013 and 2020 as the main data source,with the support of RS and GIS technology to process the land use data in Zhaozhou County,conduct spatial analysis and explore its temporal and spatial changes.The results show that:from the current land use map,Zhaozhou County is dominated by cultivated land,occupying a dominant position;from the analysis of the land use change map,we can see that grassland and unused land are increasing,and the transfer map is from cultivated land to unused land and cultivated land→Mainly grassland with a transfer area of 354.22 km^2;the largest new grassland area was from 2013 to 2020,mainly from the transfer of cultivated land,forest land and residential land;overall,the land use pattern tended to be stable from 2013 to 2020.By constructing a land-use change spatio-temporal map,the LUCC spatio-temporal analysis and research system has been enriched to provide effective methods for future land use research.
