GIS与土地生产力评价模型的集成

A Preliminary Study on the Integration of Geographical Information System with the Models for Land Productivity Evaluation

GIS与应用模型的集成是GIS应用的关键问题之一。为此,论述了土地生产力评价的数学方法和相关模型、GIS及其在土地生产力评价中的应用、GIS与土地生产力评价模型的集成方式和集成途径及目前存在的主要问题,并就未来研究提出了若干建议。

The integration of Geographical Information System (GIS) with applied models has become one of the most important issues in terms of GIS application. In this paper, the mathematical methods and the relevant models for land productivity evaluation are presented firstly. Following it, GIS and its potential applications in land productivity evaluation are put forwarded. In addition, the methods, ways and the major problems in the present studies of the integration of GIS with land productivity evaluation were discussed, respectively. Finally, some suggestions on the further studies of the integration of GIS with land productivity evaluation were proposed. [
