The response relationship between total pollution emission reduction and water quality improvement from 2011 to 2015 was analyzed by data envelopment analysis (DEA). The results show that the response relationship is different in time and space. The response relationship was further divided into four different models, and suggestions about total pollution emission controlling and water environment prevention were made under different models, in order to make total pollution emission controlling play a better role in water quality improvement. The result should provide scientific basis for precise pollution control in accordance with the water environment quality objectives of the basin.

以2011—2015年全国污染物排放总量和水环境质量数据为基础, 通过数据包络分析模型, 分析全国污染物排放总量减排与水环境质量改善的响应关系, 发现这种响应关系在时空上呈现差异化特点。进一步对二者的响应关系进行分区, 提出不同分区模式下的污染物总量控制与水污染防治对策建议, 使污染物总量控制更好地服务于水环境质量改善, 为流域水环境质量目标要求下的精准治污提供科学依据。
