In previous research on the construction of ecological security patterns (ESPs), the positioning characteristics of urban development were rarely considered, resulting in the identification of key conservation areas that are insufficient to support the ecological security of the entire region and the overall development of urban functions. Firstly, a “quality-importance-connectivity-balance” framework was created to identify ESPs and chose Liaocheng City (LC), a typical main agricultural production area, as the study site. Secondly, the ecological security level of the watershed perspective is an integrated resistance assessment method that exhibits topography, human activities, distance, and agricultural environmental impacts. Finally, the coordination pattern between agriculture and ecology was divided by the comprehensive quality of cultivated land and ESPs. A “six cores-seven belts-three zones” optimization pattern was constructed based on the components of ESPs and the distribution of cultivated land comprehensive quality. The study presents a novel approach for measuring ESPs and is an essential resource for ecological conservation and regional development planning in agroecologically complex regions. |
