Ecological land is being squeezed and fragmentized, and ecosystem functions and landscape ecological patterns are disturbed to some degree by transforming and upgrading of urban and rural development and spatial pattern adjustment in Wuhan metropolitan area. In order to implement the requirements of ecological civilization construction and green, low-carbon and environmental protection development, this article constructs the ecological network space system of the whole urban circle composed of ecological corridors and ecological nodes. Based on the morphologically spatial pattern method and the minimum cumulative resistance model, the ecological network of Wuhan metropolitan area was constructed in 4 periods (1990, 2000, 2010, and 2018), and the importance of source sites and corridors was evaluated using the landscape connectivity index and the gravity model, and proposed recommendations for ecological network management and regulation. The results show that: (1) from 1990 to 2018, the ecological source areas of Wuhan metropolitan area indicated a gradual decrease, from 16 to 10; from a spatial point of view, the large-scale source patches, which was mainly distributed in the south and north of the study area, did not change, and forest and water were the main components of the ecological source landscape, but the large reduction of fractured patches had a large impact on the regional network. (2) There were 66, 120, 99 and 45 ecological corridors in the study area in the four periods, and the number of corridors showed a decreasing trend. Important corridors were mainly distributed in the north and southeast of the study area. The exchange of matter and energy played an important role. (3) Landscape connectivity was high in the north and south, and low in the east and west. There were few ecological nodes and the large obstacles to species migration in the east and west, while high comprehensive resistance and low landscape connectivity appeared in the central region. (4) Measures are taken to enhance regional landscape connectivity, and promote biodiversity protection and the stability of the ecological network, such as the construction of stepping stones, restoration of ecological breakpoints, and differentiated protection strategies for corridors. After the development of the "two-oriented society" experimental zone, the level of the ecological network of the Wuhan metropolitan area has been optimized, but the interaction between ecological sources needs to be strengthened. The research results provide a scientific reference for the future land and space planning of the city circle.
