区域农业生态环境质量综合评价投影寻踪模型研究

A projection pursuit model for comprehensive assessment on eco-environmental quality of regional agriculture

摘要: 研究建立了区域农业生态环境质量综合评价的投影寻踪模型，利用该模型可将反映区域农业生态环境质量的多个指标转换为反映各指标综合信息的投影特征值，并根据投影特征值的大小对区域农业生态环境质量进行客观评价，方法可靠，结果合理，操作简便且易于生产应用。

Abstract: Using the projection pursuit technique, a comprehensive assessment model for regional agricultural eco-environmental quality is developed. Projection pursuit model can give a comprehensive assessment projection index based on the indexes of regional agricultural eco-environmental quality, and according to the value of projection index, a reasonable assessment result can be drawn and it is easy to do in practice.
