矿粮复合区"三生"空间冲突诊断及演化特征分析
Diagnosis and Optimization of'Production-Living-Ecology'Space Conflict in the Mine-Grain Mixed Zone
摘要
Abstract
[Objective]The aims of this study are to promote the coordination and stability of the spatial struc-ture of township-level mine-grain mixed zone,and provide scientific reference for the rational layout and implementation of territorial spatial planning.[Methods]Chengui Town in the mine-grain mixed zone was taken as an example.Five research time nodes from 1986 to 2020 were selected based on the life cycle method.The spatial pattern changes were explained by the spatial status map and transfer matrix.An improved spatial conflict measurement model was constructed.ArcGIS 10.2 in combination with Fragstats 4.2 was used to analyze the trend of spatial conflict.The conflict results were verified using Google Earth historical images.[Results]Agricultural production space and ecological space were the two types of space with the largest transfer area in and out,and the'arable land-forest land'mutual conversion had become the most significant land conversion mode.From 1986 to 2020,the overall trend of'production-living-ecology'space conflicts in Chengui Town was on the rise,and during the mining recession,the proportion of weaker,medium and strong space conflicts decreased by 3.2%,3.09% and 0.22%,respectively,and the proportion of stronger space conflicts increased by 6.51% .The conflict levels of the'production-living-ecology'space concentrated in the weak space conflict and the medium space conflict level,except for the living space,which accounted for more than 70% of the area.With the help of Google Earth historical images for comparative verifica-tion,it was found that the results of the'production-living-ecology'space conflict were consistent with the current spatial situation.[Conclusion]The mine-grain mixed zone is greatly affected by urbanization and industrialization,and the characteristics of spatial conflict are obvious,and the spatial conflict mitigation measures can be implemented with reference to the diagnosis results of spatial conflict to promote the sustainable development of the region.关键词
