DPeRS模型在重点流域面源污染优控单元划分中的应用--以吉林省为例
Application of DPeRS Model on NPS Priority Control Unit(PCU) Evaluation in Jilin Province
摘要
Abstract
During the period of the 12th Five-year Plan, the Ministry of Environmental Protection carries out division management about water pollution prevention, and it divided also control unit in combination of water quality target� After the Water Pollution Prevention Action Plan released in 2015, many new demands about water quality target and the management of control unit in key water basin were put forward� On the basis of the division of period of 12th Five-Year Plan, the control units were further refined and the 1784 control units were formatted in China combined with water quality management target and the integrity of township� However, how to realize the classification management of the control unit is a key and difficult point, and especially the division of priority control units is the key to the precision management of water environment on watershed� Using Diffuse pollution estimation with remote sensing ( DPeRS) model as a tool and Jilin province as example, this study probed into a scientific partition method of priority control units from the angel of watershed non-point source pollution, and it provided technical support for scientific basin management� The results showed: 1) In Jilin province, non-point source pollution are mainly TN and CODcr� The discharge of TN was 6384t with the total production being 2�4 ×104t and CODcr was 4552t with the total production 2�2 ×104 t in 2014� 2) The TN、 TP 、 NH+4-N and CODcr pollution were mainly located in the northwestern of Jilin province� 3) Farming was the most important source for NPS of nitrogen and phosphorus, and the livestock contributed most of NPS of CODcr�4) Among 48 control units in Jilin province, there are 21 priority control units which contains 8 first level control units whose production and discharge of pollution are higher and 13 second level control units which contains 8 source control units and 5 process control units.关键词
