| 摘 要： | 景观连通性模型可区分为点连通性模型，线连通性模型，网连通性模型和斑块连通性模型。因为点连通性、线连通性和网连通性己有很长的研究历史，相应的连通性模型（连通度）己比较成熟，所以本文的研究焦点是尚不成熟的斑块连通性模型。斑块连通性被定义为斑块中动物迁徙或植物传播运动的平均效率（或最小化运动距离）。斑块连通性模型在黄河三角洲新生湿地的应用研究结果表明，斑块连通性与人类活动强度和景观多样性负相关。

| Abstract: | The models for landscape connectivity are distinguished into model for line connectivity, one for vertex connectivity, another for network connectivity and still another for patch connectivity. Because the models for line connectivity, for vertex connectivity, and for network connectivity have been long studied and have become ripened, the model for patch connectivity is paid special attention in this paper. The patch connectivity is defined as the average movement efficiency(minimizing movement distance) of animal migrants or plant propagules in patches of a region under consideration. According to this definition, a model for landscape connectivity is mathematically deduced, which applies to GIS data. The application of model for patch connectivity in the new-born wetland of the Yellow River Delta shows that patch connectivity has a negative interrelation with human impact intensity and landscape diversity. |
