Spatial and temporal transition characteristics and influencing factors of"production-living-ecological"functions of rural areas at county level in Gansu province from the perspective of coupling
Exploring the level of coordinated development of the rural"production-living-ecological"functions,revealing the spatiotemporal leap characteristics and influencing factors of the coupling coordination relationship in its evolution process will help optimize the spatial pattern of rural regional functions and creat a new era of rural development.Based on 86 county research units in Gansu province from 1998 to 2020,this paper constructs a comprehensive evaluation index system for rural"production-living-ecological"functions,and uses the coupling coordination degree model,LISA time path,LISA spatiotemporal leap,and parametrically optimal geo-detector methods to explore the coupling coordination development level,spatiotemporal leap characteristics and influencing factors of the rural"production-living-ecological"functions.The results show that:(1)The coupling coordination degree of rural"production-living-ecological"functions at county level shows a growing development trend,gradually moving towards a benign and orderly direction,but the coupling coordination degree value is relatively low and the development speed is relatively slow.After 2013,the proportion of counties with coupling coordination state changed from serious misalignment to basic misalignment state increased rapidly.(2)On the whole,the local spatial structure of the coupling coordination degree of rural"production-living-ecological"functions in the middle region is more stable,while the southeast Gansu and Jiuquan city is more dynamic.The curvature of LISA time path shows an increasing trend from northwest to southeast in Gansu.The local spatial correlation pattern of the coupling coordination degree of each county research unit remains relatively stable,and its spatial and temporal transition has relatively strong path locking.(3)Economic development has an important effect on the improvement of coupling coordination degree,and urban radiation has an obvious promoting effect on the improvement of coupling coordination degree.The joint action of economic development and other factors directly impact the improvement of the coupling coordination degree.Other factors rooted in the natural background,such as socioeconomic conditions and location traffic conditions,are the basis for realizing the coupling coordination development of rural"production-living-ecological"functions.
