国内基于GIS的土地评价研究进展

Advancement in Research on GIS-Based Land Evaluation in China

在国内土地评价研究中,GIS的应用起步较晚但发展较快,迄今为止,GIS主要是为土地资源评价提供辅助服务。本文从土地评价的模型和方法入手,依据土地评价单元之间的相互影响和评价区域的单一性与否,将基于GIS的土地评价研究划分为单一区域非空间模型、单一区域空间模型以及多区域模型3类,其中GIS及其相关技术的应用能较好地体现土地评价单元之间静态或动态的影响。本文对这3类研究进行了较全面的阐述,是对近年来国内基于GIS的土地评价研究较系统的总结和归纳。

The application of GIS technology to land evaluation in China began much later than in other countries. But it is developing very rapidly. So far, GIS has been used mainly as an assistant in evaluation of land resources. Beginning with addressing models and methods for land evaluation, the authors divided the GIS-based land evaluation research into three types, i.e. single-region nonspatial model, single-region spatial model, and multi-region model based on interactions between land evaluation units and unicity or not of the evaluation region. The application of GIS and its related technologies may reveal the static or dynamic interactive effects between land evaluation units. This paper is a review of the three types of research, summarizing systematically advances in the research on GIS-based land evaluation in the country.
