Peasant households’ symbiotic interface of rural spatial restructuring under the perspective of symbiotic theory—A case study of Yanba village，Jiangjin district of Chongqing

Resources sharing inefficient of different types of peasant households is an important obstacle for rural spatial restructuring，and quantitative analysis of transmission interface can effectively differentiate the symbiotic relationship of different types of peasant households and identify the symbiotic interface of rural spatial restructuring which need to be strengthened in urgently. This study took Yanba village，Chongqing as a sample，and used symbiotic interface method to quantitatively analyze the characteristics of symbiotic interface of rural spatial restructuring. The results show that the symbiotic mode of five different types of peasant households is asymmetrical mutualism mode currently，and agricultural peasant households form a symbiont with obvious symbiosis，the same as non-agricultural peasant households；the symbiotic interfaces in urgently strengthened of production space consist of agricultural subsidies，land compensation mechanism，infrastructure management，the symbiotic interfaces in urgently strengthened of living space are composed of labor force quality，new rural community management，and the symbiotic interfaces in urgently strengthened of ecological space include green infrastructure construction and management.
