生境适宜度指数模型研究进展

Research advances in habitat suitability index model

生境适宜度指数(habitat suitability index,HSI)模型作为一种生境评价方法,在土地管理规划和评估中得到大量应用。本文总结了HSI模型在野生动物生境评价中的开发及应用,重点介绍了利用3S技术进行HSI建模及与其他模型耦合进行生境评价的现状;阐述了利用多种统计方法对HSI模型的评估和验证;探讨了HSI模型在主观性和非通用性等方面存在的问题和局限性,最后,就HSI模型在野生动物生境评价中的发展前景进行了展望。

As a method of habitat evaluation, habitat suitability index （HSI） model has been widely used in the programming and evaluation of land management. In this paper, the development and application of HSI model in wildlife habitat evaluation were summarized, with the focus on the establishment of HSI model by 3 S technologies and the current situation in habitat evaluation by integrating HSI model with other ecological models. The applications of various statistical approaches in evaluating and testing HSI model, as well as the limitations and pitfalls of HSI model, were discussed, and the perspectives of HSI model in wildlife habitat evaluation were approached.
