京津冀土地利用转型及生态环境效应分析

Analysis of Land Use Transition and Ecological Environment Effect in Beijing-Tianjin-Hebei Region

基于2000、2018年京津冀土地利用遥感解译数据,依托土地利用功能结构转型模型、土地利用功能的空间性转型模型和生态环境效应模型分析京津冀地区生态环境受土地利用转型产生的影响。结果表明,生活用地增加明显,生产用地有所减少,生态用地总量变化不显著;土地利用功能空间格局稳定,变化不明显;北京市为生态用地和生产用地发展重心,生态用地向东南方向偏移,生产用地向西南方向偏移,生活用地发展重心位于河北省,向北部偏移;整体生态环境质量降低,低质量区面积增加,但是空间格局变化较小。

Based on the remote sensing interpretation data of land use in Beijing-Tianjin-Hebei region in 2000 and 2018,the influence of land use transformation on the ecological environment in Beijing-Tianjin-Hebei region is analyzed based on the transformation model of land use function structure,the spatial transformation model of land use function and the ecological environment effect model.The results showed that the living land increased significantly,the production land decreased,and the total ecological land did not change significantly.The spatial pattern of land use function was stable and the change was not obvious.Beijing was the center of development of ecological land and productive land,ecological land shifted to the southeast,productive land shifted to the southwest,and residential land shifted to the north in Hebei Province.The overall ecological environment quality decreased,the low quality area increased,but the spatial pattern changed little.
