基于灰色关联投影的四川省生态环境质量定量研究

生态环境系统是一个包括自然、经济和社会等多个方面,具有信息不确知性和不完全性因素的灰色系统。以四川省为研究区,在构建生态环境评价指标体系的基础上,基于灰色系统理论和矢量投影原理,建立了生态环境质量评价的灰色关联投影模型,并运用所建模型对四川开展生态省建设前后3年的生态环境质量进行评价。结果表明,四川省自开展生态省建设以来,生态环境质量逐步提高,但仍然有进一步提高的空间。

Evaluation of Eco-environmental Quality of Sichuan Province Based on Grey Relation Projection Model

Eco-environment system involved many factors,such as natural,economic,social and so on.Owing to the unascertained and incomplete information of relative factors,it was almost a grey system.A grey relation projection model for eco-environment quality evaluation was established based on grey system theory and vector projection principle,on the premise that an indices system for eco-environment quality evaluation was established.This model was used to assess the eco-environment qualities of Sichuan Province of...
