Abstract: In the context of rapid urbanisation, building an urban-rural ecological security pattern is an important way for China to narrow the gap between urban and rural ecological security levels and to promote integrated urban-rural ecological development.The urban-rural ecological differences lead to the slow process of urban-rural ecological integration development.Taking Wuhan city as an example and urban-rural ecological integration as an orientation, this paper analyzed the current level of urban-rural ecological integration and its influencing factors.A comprehensive ecological resistance surface based on the measurement of the comprehensive impact degree of ecological integration was constructed.The ecological sources at meso-scale and theimportant ecological corridors based on the least cumulative resistance and gravity model were identified.The corridors were optimized by using a hydrological analysis model, and an overall urban-rural ecological safety pattern in Wuhan was constructed.This study showed that: (1) There was obvious spatial differentiation in the level of urban-rural ecological integration in Wuhan, and urban-rural ecology was in an unbalanced state of development; (2) The main driving force for the development of urban-rural ecological integration was the ecological environment and anthropogenic activity factors, with less socio-economic impacts; (3) A ‘three horizontal and two vertical’ network of ecological security patterns were constructed, which included 51 urban and rural ecological sources, 115 important ecological corridors, 220 radial corridors and 129 ecological nodes; (4) The ecological resistance surface corrected by the urban-rural ecological integration influence index was more in line with the urban-rural reality, and the ecological security pattern demonstrated the effect of promoting the development of urban-rural ecological integration.The ecological security pattern of urban and rural areas in Wuhan was constructed to provide a more microscopic theoretical reference for the optimization of ecological space in urban and rural areas, as well as to provide a scientific reference for the promotion of ecological integration between urban and rural areas, for the safeguarding of ecological security in urban and rural areas, and for the promotion of sustainable development in the region.
