区域污染治理能力与排污规模的协调性评价

为分析区域排污规模与污染治理的协调性,构建了排污规模与污染治理协调度模型,并以2006、2013年的数据对模型进行实证分析。结果表明,制约排污规模和污染治理协调性的主要矛盾是污染治理能力的落后,全国70%以上地区污染治理能力均滞后于污染物产生规模;国内治理能力在研究期间不断提高,区域差异在不断缩小,治理能力过度滞后的省份由14个减少到2个;除江苏外2013年其余各地区均有1项或多项污染物的治理能力滞后,其中生活废水治理能力滞后的区域最多;经济发展水平是影响协调性的重要因素,2013年协调度与地区人均GDP基本呈线性关系。模型实证计算结果与主观判断也较为吻合,具有一定的推广应用价值。

Regional Assessment on the Coordinative Degree between Regional Pollution Treatment Capacity and Pollution Scale

To analyze the coordinative relation between regional pollution scale and pollution treatment, a pollution scale-pollution treatment coordinating degree model was established. Data of 2006 and 2013 were used to do empirical analysis on the model in China. The results indicated that, The lagging pollution treatment capacity was the main restraint on coordinative relation between regional pollution scale and pollution treatment. The pollution treatment capacity was fallen behind pollution production scale in 70% regions of China. Compared 2013 to 2006, the pollution treatment capacity was improving, and regional differences were continually narrowed. The number of over backward provinces was reduced from 14 to 2. In 2013, all regions had lagged pollution treatment capacity in one or more categories of pollutants except Jiangsu. Most regions lacked the pollution treatment capacity of sanitary wastewater. Economic development level was the principal factor affecting the coordinative degree. According to the data in 2013, there was a linear relationship between coordinative degree and regional per capita GDP. The empirical calculation results were consistent with the subjective judgment, and the model is worth being promoted widely.
