Abstract

Ecological connectivity is crucial for preserving biodiversity and can successfully integrate isolated habitats. The study constructed the ecological network framework of the Panjin wetland using the minimum cumulative resistance model and gravity model. The ecological network was evaluated based on the landscape connectivity index method, and suggestions were given to optimize the zoning of the landscape pattern. Results showed that: (1) The level of interaction among various ecological source sites varies with distance and area. (2) The stability of the ecological network in the Panjin wetland was improved by increasing the ecological sources. The resulting ecological network had an α-index of 0.20, a β-index of 1.30, and an γ-index of 0.48, indicating a certain level of optimization and enhancement potential. (3) The study area was divided into four zones, each of which was analyzed and recommendations were made to achieve a stable development of the ecosystem.
