    An Analysis of Land Use Conflicts and Strategies in the Harbin–Changchun Urban Agglomeration Based on the Production–Ecological–Living Space Theory and Patch-Generating Land Use Si... by Xiaomeng Wang, Yanjun Zhang, Xiaoyan Li, Shuwen Cao

    Published 2025-01-01
    “…The results indicate the following: (1) From 2000 to 2020 and different scenarios in 2030, the PELS of the HCUA is dominated by forest ecological space (E1) and agricultural production space (P1), with no substantial alterations in the overall spatial distribution of the PELS. (2) Absolute and relative conflicts between 2000 and 2020 are mainly concentrated in the plains of the western regions, characterized by conflicts arising from the encroachment of living space on production space; however, absolute conflicts have declined annually, accompanied by a notable enhancement in ecological quality. (3) The spatial pattern of absolute conflicts in 2030 exhibits minimal variation, illustrating higher values in the western regions compared to the eastern parts, with living space surpassing ecological space and plains showing higher conflict values than mountains. …”
