Mechanism and model of comprehensive land consolidation promoting urban-rural integration in peri-urban from the perspective of symbiosis theory

Peri-urban areas is a priority for urban-rural integrated development. Comprehensive land consolidation is an effective policy tool to address urban-rural development dilemmas in peri-urban areas, and its study is vital for urban-rural integration. Based on the symbiosis theory, this study puts forward the mechanism and model of comprehensive land consolidation to promote the integrated development of urban and rural areas in peri-urban areas. It has been shown that: (1) Urban-rural symbiotic systems include symbiotic units, environments, models, and interfaces. The main obstacles to the realization of symbiotic peri-urban systems are the non-equilibrium development in the symbiotic units, the unequal mobility of the elements in the symbiotic environment, and the asymmetry and non-reciprocity of the symbiotic models. (2) Comprehensive land consolidation reshapes the symbiotic environment through the flow of elements, reconstructs the symbiotic units through spatial reconstruction, and drives the symbiotic model through functional promotion, which is the symbiotic interface that drives the evolution of urban-rural systems to symmetric and reciprocal benefits. (3) The core concept of the symmetrical and reciprocal urban-rural integration model in peri-urban areas is the equivalence of urban-rural life, economic reciprocity, and ecological sharing. The model includes urban agriculture, characteristic industry, leisure tourism, rural complex, and liveable community. (4) Huangqiao street invigorates urban-rural elements, optimizes urban-rural spatial planning, promotes urban-rural function, and forms an urban-rural integration model with characteristic industries through comprehensive land consolidation. The results provide a scientific basis for further promoting coordinated urban-rural integration and comprehensive land consolidation.
