一种基于节点删除法的候鸟栖息地重要性评估方法研究与实现

Research and application of importance of habitats of migratory bird based on node deletion

提出了一种基于节点删除法的候鸟栖息地重要性评估方法。通过计算栖息地对网络连通性的影响和候鸟停留时间的加权和,将栖息地按照重要性排序,最后利用黄海渤海区域的卫星遥测GPS数据进行了验证。实验结果表明,该方法得出的前10个最重要的栖息地中,有9个均位于IUCN所列出的区域中,因此,该方法有一定的实际意义,可用在对候鸟栖息地的重要性分析中,分析结果可以为制定候鸟保护策略提供参考。

In order to protect threatened shorebirds, this paper proposed a method to evaluate the importance of habitats based on kirchoff matrix tree theory. The method took connectivity and the time shorebirds stay as impact factors. Finally, it used the method to evaluate the importance of habitats of Bohai and Yellow Sea region. The result shows that nine of ten most important habitats are in the IUCN priority areas list. So the method can provide reference while making habitat protection strategy.
