提出了基于知识发现和决策规则基础的盐碱地ＧＩＳ和遥感分类的方法。这种方法的特点是把盐碱地分类的地学专家思想和区域专家的思想应用到ＧＩＳ数据挖掘中，并把从ＧＩＳ数据库中发现的知识，按一定的规则应用到盐碱地分类的决策中。经过对华北平原黑龙港地区盐碱地分类实例的研究证明，该研究方法不仅简化了数据运算过程，节省数据运算时间，而且会减少或避免分类过程中人为误差的产生
A method based on knowledge discovery and decision rules based on saline-alkali land GIS and remote sensing classification is proposed. This method is characterized by the application of the idea of geoscience experts classified in saline land and the ideas of regional experts to GIS data mining and the knowledge found in GIS databases is applied to the decision-making of saline-alkali land classification according to certain rules. After a case study of the classification of saline land in Heilonggang area of North China Plain, this method not only simplifies the data computing process and saves data computing time, but also reduces or avoids the human error in the classification process
