摘要
从生态安全模型与评价指标体系入手,研究了数据挖掘技术在区域生态安全评价专家系统中的应用目标与任务；综合运用神经网络、关联规则挖掘等人工智能方法,实现了对生态数据的挖掘,结合梯度法对挖掘的结果进行了必要的处理,使最终的结果更真实合理；探讨了数据挖掘技术引入生态专家系统后系统所具有的特点。
From the system of evaluation system and the model of ecological security, this paper researches the goal and task for applying data mining in expert system of regional ecological security assessment. It realizes ecological data mining by synthetically exercising neural network and association rules method and makes the final result true and sound by dealing with the mined results with gradient method. Finally, it discusses the features of ecological expert system using technology of data mining.
