Abstract
Human activities and climate change have resulted in an increasing fragmentation of forest landscapes, and the conflict between biodiversity protection and economic development has become more pronounced. The establishment of forest ecological networks can be a vital part of biodiversity conservation and sustainable forest development. Using Jindong Forest Farm as the study area, this study combines the forest ecological suitability index, morphological spatial pattern analysis, the area method, and the landscape connectivity index (PC, IIC). This will identify ecological source areas in the study area, extract ecological corridors using the minimum cumulative resistance model and the gravity model, and construct a forest ecological network with ecological source areas as points and ecological corridors as edges. This study identified 11 forest patches in highly suitable habitat regions as ecological source regions, and 54 potential corridors were extracted. The study’s results show that a careful analysis of the forest landscape’s ecological suitability and morphological spatial pattern provides a scientific method for the rational selection of ecological source regions and serves as a reference for protecting forest species diversity and sustainable forest development.

Summary
As the backbone of terrestrial ecosystems, forest ecosystems are indispensable for ecological balance and biodiversity conservation [1]. Irrational forest management has resulted in the loss and fragmentation of forest habitats and the destruction of ecological corridors, resulting in a decrease in forest landscape connectivity and, as a result, biodiversity [2–4]. Forest biodiversity conservation and sustainable forest development have become matters of primary concern [5,6]. Since landscape connectivity refers to how the landscape facilitates or inhibits species movement between habitat patches, improving and maintaining forest landscape connectivity is an effective way to protect forest biodiversity [7,8]. Numerous studies have demonstrated that increasing landscape connectivity can improve species’ viability and maintain genetic diversity by allowing species to move flexibly across the landscape in response to changing resources and threats [9,10]. As a result, improving connectivity is a critical area of research in biodiversity conservation
