陕西省区域生态环境质量的灰色综合评估

Grey Comprehensive Assessment of Regional Ecological Environment Quality in Shaanxi Province

以陕西省为研究对象,构建了科学的区域生态环境质量评价指标体系,并采用灰色综合评估方法对全省区域生态环境质量现状进行了综合评价。评价结果显示关中地区的宝鸡、咸阳以及陕南地区的安康、汉中生态环境质量较好,关中地区的西安和渭南生态环境质量中等,而关中地区的铜川以及陕北地区的延安、榆林生态环境质量较差,陕西省各地区生态环境质量总的趋势为中南部优于北部,并据此提出全省生态环境保护及经济可持续发展建议。
