Analysis on Spatial-temporal Pattern of Land Use Change and Coupling Coordination Degree in Huize County from the Perspective of "Production-Living-Ecological Space"
In undeveloped areas with fragile ecology and remote locations,conflicts between ecological environmen-tal protection and economic development has coexisted for a long time.In order to effectively solve this development dilemma,Huize County in Qujing City is taken as the research object,and ArcGIS10.8 tool is used to analyzes the land-use change of"Production-Living-Ecological Space"in the study area in 2000,2010 and 2020.Spatio-tempo-ral analysis,transfer matrix and coupling coordination degree model are used to analyze the spatio-temporal charac-teristics and influencing factors of land use change under the perspective of"Production-Living-Ecological Space"in the study area.The results showed that:(1)The land cover of Huize County is dominated by forest land,grassland and cropland.The area of construction land has grown significantly and is mainly located in the vicinity of towns,while the area of unutilized land has not changed significantly.(2)Mutual transformation occurs between built-up land,cropland,forest land,grassland,and water bodies,with the greatest amount of grassland-forestland transforma-tion,but also a significant portion of forest land and cropland transformed into grassland;in addition,built-up land,unutilized land,and water bodies all have small interconversions,but the changes are not significant.(3)The change in the coupling coordination degree D of Production-Living-Ecological Space is similar to the change in the cou-pling degree C,which is mainly characterized by an increase in the proportion of moderately functionally coordinated zones and a decrease in the proportion of highly functionally uncoordinated zones.Overall,the tate of land use change in Huize County is still slow relative to large towns.The results of the study can provide scientific basis for local sustainable development.
