摘要
为充分利用多年积累的环境监测时序立体数据,全面反映沿海城市环境质量发展状况,对其综合评价指标体系和评价方法进行了研究。选取大气、淡水、海水、声、生态和污染排放6种环境要素共13项评价指标,构建沿海城市环境质量综合评价指标体系,采用"拉开档次法"进行动态评价,实现多区域、多时段综合环境质量纵横向比较,评价方法客观,计算量小,评价过程透明,可操作性强,评价结论唯一无争议,并以大连市为例,验证了方法的可行性。
To make the most of the accumulated multi-dimensional time series data,the paper studied the comprehensive evaluation index system and evaluation method to reflect the whole environmental quality of coastal cities. A comprehensive evaluation system was constructed from six elements of atmosphere,fresh water,sea water,noise,ecology and pollution discharge,which contained 13 underlying indexes. The scatter degree method was used for dynamic comprehensive evaluation to compare the environmental quality both vertically and horizontally. The method had the advantages of objectivity,less calculation,transparent process and high operability. The assessment result was unique without dispute. A case study was carried out in Dalian to verify the feasibility.
