Study on the Spatial Optimization of6Production-Living-Ecology'in Mine-Grain Complex Area of Dexing City Based on Suitability and Spatial Function Value
摘要
Abstract
[Objective]The aims of this study are to carry out in-depth functional evaluation and spatial regula-tion optimization of'production-living-ecological',to coordinate and reconstruct unreasonable spatial layout and structure,to alleviate spatial conflicts between mine and grain,and to provide reference for land space governance and regional high-quality development.[Methods]The mine-grain mixed zone of Dexing City was taken as an example.Spatial suitability evaluation,functional value calculation and spatial autocorrelation analysis were used to study the'production-living-ecological'space optimization of the study area based on AVC'three forces'theory.[Results](1)The agricultural and industrial production space concentrated in the southwest and north,respectively.The concentration of living space decreased from northwest to south-east,while the ecological space widely distributed and balanced.(2)The production and ecological space mostly clustered,while the functional aggregation of living space was weak and scattered,and the mining area had a negative impact on its spatial suitability,functional value and aggregation degree.(3)After spatial reconstruction,the functional value of living space and ecological space increased from 194.86 million yuan and 9.075 5 billion yuan to 195.18 million yuan and 9.077 89 billion yuan,respectively.[Conclusion]After comprehensive consideration of suitability,spatial function value and concentration degree for spatial optimi-zation and reconstruction,the living and ecological spatial function values of the study area was improved.The spatial distribution of various types tended to concentrate,which alleviated the negative impact of the mining area on people's life and grain production.In the future,systematic governance and control should be carried out for all kinds of spaces,and the development of mining areas should be strictly controlled to ensure production,life and ecological functions.关键词
