[Objective] The analysis of the spatial and temporal evolution patterns and drivers of ecological lands is of great significance to optimize the ecological security pattern and enhance the sustainable supply of regional ecosystem services in Hubei Province. [Methods] Based on the land survey data, the area and structure, landscape pattern, spatial and temporal changes and drivers of major ecological lands in Hubei Province during 2009—2019 were analyzed by using the landscape pattern indies and Geodetector model. [Results](1)The total area of ecological lands in Hubei Province showed a rising trend, while the contiguity of major ecological lands decreased during 2009—2019, and the risk of interference and erosion of ecological lands by human activities also increased at the same time.(2)Urbanization and agricultural production activities, such as the development of arable land and orchard, were the main causes of ecological lands loss. On the other hand, forest(lake)rehabilitation and land consolidation project were the main ways to replenish ecological lands in Hubei Province.(3)The major drivers of ecological land change in Hubei Province included average annual precipitation, urbanization rate, per capita arable land area, gross value of primary industry, and edge density and landscape shape index of the ecological land patches. Among them, the interaction between urbanization rate and primary industry output could explain 86.6% of ecological land changes, indicating that the combined effect of urbanization and agricultural development was the main cause of ecological land changes in Hubei Province. [Conclusion] The total amount of ecological land in Hubei Province was improving. However, attention should be focused on the negative impacts of ecological land spatial patterns and human activities, such as living and production, on the ecological land. In the future, it is necessary to optimize the ecological space protection pattern, enhance the utilization efficiency of agricultural and built-up land, and build a solid ecological barrier in the middle reaches of the Yangtze River.
