国外基于GIS土地适宜性评价研究进展及展望

土地适宜性评价是土地利用总体规划的一项基本工作和重要内容。随着全球人口的增长及环境问题的日益加剧，研究探讨土地适宜性是处理好人口与资源、走可持续发展之路的重要课题。通过对大量文献的检索，较为系统地总结了国外学者有关基于GIS的土地适宜性评价的观点，按照土地适宜性评价方法的发展历程，将其分为三个方面：计算机辅助叠加制图、基于GIS多指标决策方法和人工智能建模。对于目前常用的基于GIS多指标决策和人工智能建模两种方法进行了评析；并提出评价方法正向精确化、综合化和动态化的方向发展，建议注重土地适宜性评价方法的空间尺度转换，力争在未来实现网络化、可视化。

An Overview and Perspective of Alien Land Suitability Evaluation Study Based on GIS Technology

Land suitability evaluation is the basis and core of overall land use planning. With global population increasing and environmental problems deteriorating, it is important and urgent to implement the research on land suitability for dealing with the relation between population and resources and with sustainable development. Based on indexing an amount of references, the authors systematically summarized viewpoints of alien researchers on land suitability with GIS and classified the related methodologies into three aspects: Computer-assisted overlay mapping, multi-criteria decision-making methods and artificial intelligence methods. In addition, authors analyzed the latter two methodologies, put forward the orientation of more accuracy, integration and dynamics in this regard, and suggested to realize methodologies transition at different spatial scales and network assessment and evaluation visualization in the future.
