Amidst global climate warming and rapid urbanization, ecological and environmental issues are becoming increasingly prominent. Constructing a multi-functional coupled ecological network pattern is essential for promoting the synergy among ecological protection, climate regulation, and economic development. This study focuses on Anhui Province, characterized by diverse topographical features. Utilizing “source and sink” theory, the study employs a combination of Morphological Spatial Pattern Analysis (MSPA), landscape connectivity indices, local spatial autocorrelation, and circuit theory to construct single-factor networks for biodiversity conservation, thermal environment mitigation, and economic development. The analysis of spatial elements such as “source” areas, corridors, ecological strategic points, and ecological nodes led to the formation of an optimized multi-level, multi-functional composite ecological network pattern based on ecology, climate, and economy. The results indicate that: (1) Anhui Province has 14 ecological “source” landscapes and 31 ecological “sink” landscapes. There are 29 climate “source” landscapes and 21 climate “sink” landscapes. Additionally, there are 30 economic “source” landscapes and 22 economic “sink” landscapes. The biological migration corridors are primarily concentrated in Northern and Central Anhui Province, while climate corridors are distributed throughout the province. Economic corridors are relatively dense and dispersed across var...
