Many wetlands in the Yellow River Delta have degraded as a result of drainage and conversion for development and other land uses in recent years. To provide information for targeted protection and restoration of degraded wetlands, we explored the landscape ecological network based on the wetland classification data in 2016 by using landscape connectivity index, least-cost distance model, gravity model and digital elevation model hydrological analysis. The landscape ecological network consisted of 10 ecological sources, 35 ecological corridors (13 primary ecological corridors, 22 secondary ecological corridors) with a width of 200 m and 5 ecological nodes. The corridors constructed with patch and patch centroid were different, and the ecological corridors constructed with patch unit show a minimum accumulated resistance. The distribution of ecological sources and nodes was in good agreement with the actual conditions, and the network was reliable. The establishment of this ecological network will play a key role in the improvement of landscape connectivity, optimization of the ecological environment and increase in species diversity in the wetland, which can provide a reference for the optimization and restoration of the overall landscape pattern in this region.

近年来，黄河三角洲的许多湿地由于排水和改建发展以及其他土地用途而退化。为了提供有针对性的保护和退化湿地恢复的信息，我们使用景观连通性指数，最小成本距离模型，重力模型和数字高程模型水文分析，基于2016年的湿地分类数据探索了景观生态网络。景观生态网络由10个生态源，35个生态走廊（13个主要生态走廊，22个次要生态走廊）组成，其宽度为200 m，共有5个生态节点。斑块和斑块质心构成的廊道不同，斑块单元构成的生态廊道具有最小的累积阻力。生态源和节点的分布与实际情况吻合良好，网络可靠。该生态网络的建立将在改善景观连通性，优化生态环境和增加湿地物种多样性方面发挥关键作用，这可为该地区整体景观格局的优化和恢复提供参考。 。
