2008—2013年晋北地区土地利用/覆被变化研究

旨在了解人类活动对晋北地区土地利用/覆被变化(LUCC)的影响，为研究区合理利用土地资源、优化土地利用格局以及促进区域经济社会协调发展提供科学依据。利用晋北地区2008—2013 年的TM遥感影像数据，在ERDAS、ArcGIS 等软件的技术支持下，解译影像处理数据并建立土地利用变化转移矩阵，对研究区域近5 年来土地利用/覆被变化进行研究。结果表明：2008—2013 年期间，晋北地区耕地面积减少62561.10 hm2，林地增加55774.23 hm2，居民工矿建设用地增加22895.49 hm2，草地减少15395.60 hm2，水域面积增加1090.24 hm2，未利用地面积减少1803.29 hm2。这与研究区域在研究时段内大量退耕还林还草的生态建设、城镇化快速发展、经济持续增长等人类活动相关。综上，2008—2013 年期间，晋北地区土地利用与覆被发生了较大变化。

Land Use and Land Cover Change in Northern Shanxi: 2008 - 2013

The study aims to understand the influence of human activities on land use and land cover change (LUCC) in northern Shanxi, and provide a basis for the rational utilization of land resources, the optimization of land use pattern and the promotion of coordinated regional economic and social development. Using the TM remote sensing image data from 2008 to 2013 in northern Shanxi, with the technical support of ERDAS and ArcGIS, image processing data were interpreted, and a land use change transfer matrix was established. Land use and land cover change in the five years was studied. The results showed that during the period of 2008- 2013, the cultivated land area in northern Shanxi decreased by 62561.10 hm2, the forest land increased by 55774.23 hm2, the land for residential, industrial and mining construction increased by 22895.49 hm2, the grassland decreased by 15395.60 hm2, the area of the water area increased by 1090.24 hm2, and the area of the unused area was reduced by 1803.29 hm2. The status is related to the ecological construction, rapid development of urbanization, sustained economic growth and other human activities in the research area during the study period. In summary, during 2008-2013, great changes have taken place in land use and land cover change in northern Shanxi.
