| 摘 要： | 在分析PSR模型、广泛听取专家意见的基础上,建立了生态环境评价指标体系。对评价因子量化分级,利用层次分析法确定权重后对郑州市的生态环境进行评价,并利用灰色系统理论,建立了灰色系统的GM(1,1)预测模型,对郑州市的生态环境质量做了短期预测分析。结果表明,郑州市的生态环境质量比较低,接近中度警情的值域。最后对评价结果做了分析,提出了改善郑州市生态环境的建议。

| Abstract: | Based on the model of PSR(Pressure-Sate-Response) and the advice of experts,an ecological evaluation index system was set up.Zhengzhou ecological environment quality was evaluated by grading the evaluation factors and using the AHP to determine the weight.The gray system theory was used to establish a GM(1,1)earning model.Based on the model,a short-term forecast analysis of ecological environment in Zhengzhou was done.The result indicated that the Zhengzhou ecological environment quality is not very good,near the value field of middle-grade warning.Finally,the result of evaluation was analyzed and some suggestions about improving the Zhengzhou ecological environment were put forward. |
