中文摘要	对吕梁市景观空间格局随地形起伏度的分布特征进行分析,旨在为脆弱生态环境治理和景观生态建设提供理论依据。基于ASTER GDEM数据提取吕梁市地形起伏度,利用2008年Landsat- 5TM和2018年Landsat-8OLI数据解译结果,运用Fragstats 4.2对斑块类型水平景观指数进行了计算,并对吕梁市景观空间格局随不同地形起伏度的分异特征进行了分析探讨。结果表明:1)吕梁市的地形起伏度以丘陵为主,其面积占研究区的66.19%。景观类型则以黄土地貌和林地为主。2)平原地区,未利用地的斑块面积由324.12 km~2减小为133.62 km~2;水域连通性增大;受水分影响大的景观类型优势度明显,分布集中;居民点的最大斑块指数减小0.60%,斑块数量增加2 186个,景观形状指数减少66.05,散布与并列系数增大13.07%,表明其分布范围扩大,分布越来越密集,斑块形状愈加规整,斑块连通性加强;未利用地的景观形状指数减少96.01,其斑块结构愈加简化。台地地区,黄土地貌、林地和旱地的斑块面积分别增加278.03、505.97、284.64 km~2。丘陵地区,2018年林地的最大斑块指数达14.76%,为优势景观类型;水域和旱地的景观形状指数分别由166.54、363.26增加到2 24.32、454.14;水域、林地、旱地的斑块破碎度增大,斑块类型更丰富。小起伏山地,林地的斑块面积由86.50km~2增加到103.58 km~2,林地为该区的主要景观类型。随着地形起伏度的变化,吕梁市景观空间格局分异特征明显。
英文摘要	This paper analyzed the distribution characteristics of landscape spatial pattern with relief amplitude in Luliang city,to provide theoretical basis for the management of fragile ecological environment and the construction of landscape ecology.The relief amplitude of Luliang city was extracted with the neighborhood statistics analysis method based on ASTER GDEM data,2008Landsat-5TM and 2018Landsat-8OLI image data were used to interpreter the results.The class-level landscape indices were calculated by Fragstats4.2.The differentiation characteristics of landscape spatial pattern in Luliang city at different topographic relief zones was analyzed and discussed.The results showed that 1)the relief amplitude of Luliang city was mainly in hilly form,which accounted for 66.19% of the study area.The landscape types were mainly loess landform and woodland.2)In plain region,the unused land decreased from 324.12 km~2 to 133.62 km~2.The water connectivity increased,the dominance of the landscape types that were affected mostly by water was obvious and the distribution was concentrated.The largest patch index of residential area decreased by 0.60%,while the number of patches increased by 2 186.The landscape shape index decreased by 66.05,and the interspersion and juxtaposition index increased by 13.07%,indicating that the distribution range was enlarged,the distribution was more and more dense,the patch shape was more and more regular,and the patch connectivity was enhanced.The landscape shape index of unused land decreased by 96.01,and the patch structure became more and more simplified.In the plateau area,the areas of loess landform,woodland and arid land increased by 278.03 km~2,505.97 km~2 and 284.64 km~2,respectively.In hilly area,the largest patch index of woodland accounted for 14.76%in 2018,which was the dominant landscape type.The landscape shape index of water area and arid land increased from 166.54,363.26 to 224.32,454.14,respectively.The patch fragmentation degree in water area,woodland and arid land increased,and patch types were more abundant.In small undulating mountains,the area of woodland increased from 86.50 km~2 to 103.58 km~2,and woodland was the main landscape type in this area.The differentiation characteristics of landscape spatial pattern with relief amplitude was significant.
