| Abstract: |
| [Purpose] Agricultural non-point sources and soil heavy metal pollution have seriously threatened the green and sustainable development of agriculture in my country. The development of a pollution management decision-making system for pollution supervision and management，and the establishment of a workflow-based agricultural pollution management decision-making model will help provide scientific guidance and decision，which will strengthen soil pollution control and carry out soil remediation.[Method] This paper uses workflow technology and pollution evaluation model organization methods to separate the construction of agricultural pollution model from the execution of workflow process，which makes the design of workflow process easier to understand and analyze，and at the same time reduces the dependence between the agricultural pollution evaluation model and the operating environment. It can be applied to the management of agricultural non-point sources and heavy metal pollution of different granularity and levels.［ Result/[Conclusion] Through workflow technology，a workflow framework for model construction，reorganization，reuse，and deployment of agricultural pollution in different decision-making scenarios is established，so that the agricultural pollution evaluation model can be automatically operated，controlled，and managed in a computer environment，finally realizing a flexible paradigm Organization and usage model. The construction of agricultural pollution models based on workflow can protect and rationally use land resources，standardize and simplify the data analysis process in the decision-making management process，and improve the efficiency of data utilization. |
