Spatio-temporal characteristics and evolution of production-living-ecological space function coupling coordination in Wumeng Mountain area
In order to explore the spatio-temporal characteristics and interactive relationship between the functions of the county and rural areas in Wumeng Mountain area,this study took the county area as the basic research unit,took the vector database of land use change survey and DEM data of Ludian County in 2009,2014 and 2018 as the basic data sources,and used the coupling coordination degree and inverse distance weight interpolation method to analyze the coupling coordination between the func-tions of rural areas and rural areas.The spatial area composition and variation characteristics of cou-pling coordination degree of production-living-ecological functions at different altitudes,slopes and slope directions were analyzed.The results show that:1)The production function is dominant in the study area and the spatial distribution is relatively balanced;The living functions are mainly distributed in the dam area,rural residential areas and towns,and gradually tend to be concentrated with the pas-sage of time.Ecological functions are mainly distributed in the northern,northwestern and central re-gions of the study area,which are rich in woodland and grassland,and show obvious spatial complemen-tarity with production and living functions.2)There are five types of coupling coordination degree of the production-living-ecological functions in the study area,with the high coordination and moderate co-ordination areas as the main keynote.The spatial pattern is higher in the central and southern parts of the study area,and the temporal variation is small.Only a few clusters of low coupling coordination are-as are added in the southwest.3)In terms of topographic characteristics,coupling coordination with high values are distributed between 2 000 m and 2 500 m in 2009 and 2014,and the area of coupling coordination with high values is the largest at 2500 m in 2018.When the slope is less than 5°,the com-bination of moderate coordination zone and high coordination zone occupies the largest land area.With the increase of the slope,the coupling coordination degree level gradually decreases.When the slope di-rection is in positive sun direction,the combination of moderate coordination and high coordination area accounts for the largest proportion,followed by the slope direction is in half sun direction.
