摘要：当今农业科学中，地理信息系统（GIS）的应用是一个新的重要研究领域，包括GIS在内的一些农业高新技术以及成为农业现代化的支撑，而且GIS与其他高新技术的结合在农业中的运用也是我国农业今后发展的重要方向。本文介绍了在GIS支持下的土地适宜性评价的基本原理与一般方法，以及GIS在评价中的应用。根据土地适宜性评价原则，以山东省东营市土地适宜性评价为例，探讨运用GIS技术对用地的自然、社会属性进行综合评价的数量化方法，结合当地实际情况，确定评价因子，运用层次分析法（AHP）来计算评价因子的权重值，依此来建立土地适宜性评价模型，进行土地适宜性评价研究，将GIS引入到土地适宜性的空间评价中评价方法更科学，使评价结果能更好地为土地利用和规划服务。利用GIS软件将原始点位数据生成面数据，再针对生成的数据进行裁剪、转换及综合分析等处理，对研究区土地资源的适宜性进行评价，为土地资源的合理开发利用提供科学根据。

Land Suitability Assessment Based on GIS——Take the Shandong Dongying City as the Example
Abstract：In today’s agricultural science, the application of geographic information system (GIS) is an important new research field. Some agricultural high technologies including GIS are crucial to the agricultural modernization and the application of combination between GIS and other high technologies is also an important direction for our country’s agriculture development. This paper introduces the fundamental and the general method of land suitability evaluation with support of GIS, and applications of GIS in land evaluation. And based on the land suitability evaluation principles, in Shandong province Dongying city land suitability assessment, discusses the quantitative method for comprehensive evaluation of natural, social attribute by using GIS technology, combined with the local actual situation, adopts the AHP to calculate the weight value of the evaluation factor in order to establish the land suitability evaluation model and carry out the land suitability evaluation study, GIS will be introduced to the land suitability evaluation of land resources in the space of more scientific evaluation method, the evaluation results can be better for the land use and planning services. The initial point position data generate the plane data with the software, and then, using the software to cut, convert and analyze on the new data. Following, the land suitability was evaluated roughly, which will provide scientific basis for the rational development and utilization of land resources.
