- Abstract:
-
In order to explore the internal relationship of ‘production-living-ecological' space, taking rural settlement plaques as the research unit, we used the Gaussian based 2-step floating catchment area(2 SFCA)method and kernel density analysis to analyze the differentiation characteristics of rural settlement and its production-living-ecological space in Qixingguan district, and used the coupling coordination degree model to quantitatively calculate the coupling degree and coupling coordinate degree of rural settlement. The results show that:(1)the rural settlement as a whole shows the characteristics of ‘large distribution but small cluster' in Qixingguan district, the circle structure of living space is prominent, the difference between north and south of production space is significant, and the ecological space is relatively scattered;(2)there are four types of coupling degrees and five types of coupling coordination degrees in the spatial function of ‘production-living-ecological' space of rural settlement, the coupling coordination state is subject to the ‘core-edge' mode;(3)there is strong central city direction of coupling coordination status among every two of the rural settlement ‘production-living-ecological' space function, and the coupling coordination of ‘production-ecological' space is higher than that of ‘production-living' space and ‘living-ecological' space in Qixingguan district. The coupling coordination level of ‘production-living-ecological' space of rural settlement in Qixingguan district needs to be improved, and the rural ‘production-living-ecological' space needs to be planned scientifically to promote the healthy development of rural in karst mountainous areas.
