Study On Spatial Evolution Characteristics Of Production-living-ecological Space In Farming-pastoral Ecotone Of Inner Mongolia

In this paper,the typical region of China’s farming-pastoral ecotone,Inner Mongolia farming-pastoral ecotone,is taken as the research area.The land use data from 2000 to 2020 are used to identify the quantitative ratio and spatial allocation of the Production-Living-Ecological spaces in the farming-pastoral ecotone of Inner Mongolia.With the help of land use dynamic degree,transfer matrix,Gini coefficient,gravity center transfer model and the econometric model in landscape ecology method,the Arc GIS software is used Based on the spatial cluster analysis,this paper analyzes the spatial evolution characteristics of the three crops in the farming-pastoral ecotone of Inner Mongolia from 2000 to 2020 from the aspects of quantitative structure and landscape structure,and identifies the spatial pattern characteristics of the three crops in the farming-pastoral ecotone of Inner Mongolia.Research shows:(1)From 2000 to 2020,the agglomeration level of the three ecological functions in the farming pastoral ecotone of Inner Mongolia the agglomeration level shows a trend of continuous decline,which shows that the fragmentation trend of space is further enhanced and higher.There are obvious regional differences in the Transformation of "Production-Living-Ecological" Space at the Mode Level.The production function although the production function space has expanded to a certain extent,the function value is constantly decreasing;The living function space area and function value showed an expanding trend.The ecological function space has shrunk to a great extent,but the function value is on the rise.There are obvious autocorrelation characteristics among these three functional spaces,the spatial aggregation characteristics are obvious,and the spatial autocorrelation the decrease of space indicates that it presents more prominent fragmentation characteristics.(2)There is a spatial synergy relationship between the production and living functions of the "Production-Living-Ecological" functions.There is an inherent trade-off between production ecological function and the life ecological function.The trade-off and synergy relationship of each unit is the same,which shows that there is a spatial synergy relationship between production and life functions gradually decreased.The spatial trade-off relationship between production and ecological functions.The spatial synergy between production and life functions is weakening with time.The spatial trade-off between production and ecological functions gradually weakens and turns to synergy with time.The trade-off relationship between life and ecological function is gradually increasing with time.(3)The pattern of different functions such as production,life and ecology have undergone great changes due to socio-economic factors,among which population density is a relatively influential indicator.The second influential factor is the natural influence factor,which has It has a great influence on these different functional spaces.
