Research on potential conflict identification and pattern optimization of territorial space in Chengde City based on the suitability evaluation of"Ecology-Agriculture-Town"
The scientific identification and mediation of potential conflicts in land space utili-zation was the foundation of land space optimization.In order to optimize the spatial pattern of Chengde City,the suitability evaluation system of ecological protection,agricultural pro-duction and urban development was established by integrating the factors of land resources,water resources,meteorology and disasters in this paper.The two-dimensional and three-di-mensional potential conflict identification models were used to reveal the intensity and spatial distribution of different types of potential conflicts and the land spatial pattern was recon-structed following the principle of"ecological protection priority,agricultural green develop-ment and appropriate urban development".It was concluded that:(1)The spatial suitability of Chengde city showed the characteristics of"ecological protection was important,agricul-tural production and urban construction were generally suitable";(2)There was little differ-ence in the intensity of potential conflicts in Chengde City,mainly light potential conflicts and no potential conflicts.The potential conflicts between ecological protection-agricultural production-urban construction,and the potential conflicts between agricultural production-urban construction were dominated,the conflict areas were 72.66％and 55.31％,respec-tively;(3)The types of potential conflicts between different functions had certain non-equi-librium in administrative units;(4)Taking potential conflicts and the current situation of territorial space utilization as guidance,the formulation of the optimal pattern of territorial space and partitioning strategies were scientific guide to the sustainable use of space.
