摘要
基于内蒙古自治区生态环境脆弱 ,自我调节能力差 ,自然环境恶化问题突出 ,提出内蒙古生态环境预警指标体系 ,选用层次分析法将内蒙古 7个生态建设保护区、13个预警指标构成层次模型。通过构造判断矩阵、模型的层次单排序、一致性检验和总排序 ,得出内蒙古 7个生态建设保护区生态环境危急程度和各区预警因子的权重及内蒙古生态环境问题严重程度总排序。最后对各区域预警结果进行了详细分析 ,为内蒙古生态环境的保护与治理提供依据。
Nei Monggol autonomous region has a fragile and deterioration environment and is poor in self-regulating.An ecological enviroment precaution system is presented for this region in the paper based on a hierarchical model,which is established with the aid of the method of Analytic Hierarchy Process and consists of thirteen precaution indices for seven ecological construture and protective subregions of Nei Monggol.Through constituting judge matrixes,sorting model hierarchies,and testing consistency,crisis levels of the ecological environment are obtained for the seven subregions,and weights of the precaution factors and sorted orders of the crisis levels are estimated for each of them.Finally,detailed analysis is made in respect to the precaution results from the model.It can serve as a useful tool for protection and administration of Nei Monggol ecological environment.
