【摘要】：将系统科学中表征系统要素重要性程度的信息熵理论引入到流域水污染物总量分配领域,综合考虑研究对象的经济、社会、环境等总量减排因素情况下,遴选出人均GDP、人均排放强度、重点行业增加值比重、工业废水COD处理率、生活废水COD削减率和单位国土面积水资源量六项分配依据指标,构建一个定量化的基于公平性的流域间水污染物总量的公平分配模型,并以松花江流域"十二五"总量分配为例进行了研究。结果表明:"十二五"期间,松花江流域的各地区之间COD削减率存在明显差异,其中大庆市COD削减率最高(22.55%),辽源市削减率最低(6.34%),10个地区的COD削减率高于目标削减率(12.43%),COD削减量最大的前五个地区是哈尔滨市、长春市、吉林市、齐齐哈尔市与白城市,其与分配基准年排放量大小并未呈一一对应关系。模型模拟表明,应用信息熵理论来衡量流域间水污染物总量的公平分配具有一定可靠性,其排除了人为因素对水污染物总量分配的影响,使分配结果更具公平性,易为各污染源区域所接受,可在一定程度上位重点流域水污染物总量削减工作提供了技术支持。
[Abstract]:The information entropy theory, which represents the importance of the system elements, is introduced into the field of the total distribution of water pollutants in the basin, and the economic, social, environmental and other total emission reduction factors of the research object are considered comprehensively. Six allocation criteria, such as per capita GDP, per capita emission intensity, proportion of added value in key industries, COD treatment rate of industrial wastewater, COD reduction rate of domestic wastewater and water resources per unit land area, were selected. A quantitative fair distribution model of the total amount of water pollutants among watersheds based on equity was constructed, and a case study was carried out in the Songhua River Basin in the 12th Five-Year Plan. The results show that during the 12th Five-Year Plan period, there are obvious differences in COD reduction rate among different regions of Songhua River Basin. Among them, Daqing City has the highest COD reduction rate (22.55%), Liaoyuan City has the lowest reduction rate (6.34%), and the top five areas with the highest COD reduction rate in 10 regions are Harbin, Changchun, Jilin, Qiqihar and Baicheng, and the top five areas with the largest reduction amount are Harbin, Changchun, Jilin, Qiqihar and Baicheng, and the top five areas with the largest amount of COD reduction are Harbin, Changchun, Jilin, Qiqihar and Baicheng. It does not have a one-to-one relationship with the emission size of the assigned base year. The model simulation shows that applying the information entropy theory to measure the fair distribution of the total amount of water pollutants among watersheds has a certain reliability, which excludes the influence of human factors on the distribution of the total amount of water pollutants, and makes the distribution result more equitable. It is easy to be accepted by various pollution source areas and can provide technical support for reducing the total amount of water pollutants in the upper key watershed to a certain extent.
