| Summary: | [Objective] The research on the transition of rural settlements is carried out by coupling the dominant and recessive morphologies of land use, providing theoretical basis and practical reference for coordinating the conflicts between the dominant and recessive morphologies of rural settlements. [Methods] This paper draws on the “conflict-coordination” theoretical model of regional land use, and introduces the coupling coordination model, Pearson correlation coefficient and grey correlation degree model to analyze the internal correlation mechanism of the transition of rural settlements in Tianjin from 1980 to 2020. [Results] (1) From 1980 to 2020, the dominant morphology and recessive morphologies index of rural settlements in Tianjin showed an upward trend. The dominant and recessive morphologies of the rural settlements in the four districts around the city underwent transition. Specifically, the mutation point of dominant morphology in Dongli District and Jinnan District appeared between 2000 to 2005, while it occurred around 2000 in Xiqing District and between 2005 and 2010 in Beichen District. The mutation point of recessive morphology appeared in Dongli District, Jinnan District and Beichen District around 2005, while it in Xiqing District appeared between 2000 and 2005. (2) The coupling coordination between dominant and recessive morphologies of rural settlements in Tianjin has gone through three stages: low coupling coordination, medium coupling coordination and basic coupling coordination, and the coupling coordination degree showed a decreasing trend from the four urban districts to five suburban districts and the Binhai New District. (3) From 1980 to 2000, the area, patch number and patch density of dominant morphology of rural settlements significantly affected the recessive morphology, while the patch number, per capita area and cohesion index from 2000 to 2010, and the index of cohesion index, per capita area and landscape shape index from 2010 to 2020 were also impactful. [Conclusion] The research results of this paper can provide scientific basis for optimizing the recessive morphology by adjusting the dominant morphology of rural settlements, coordinating the evolutionary conflict between them, and realizing the transition and reconstruction of rural settlements. |
