Abstract：One of the bottlenecks in the prevention and control of agricultural non-point source polution is the deficiency of a rational risk assessment method，which makes it challenging to identify effective approaches in practical work. This research employed the entropy weight method and expert scoring method in combination with the local standards of Chongqing City to construct a risk assessment system for non-point source pollution of large-scale planting based on the“source-flow-sink”concept，and conducted an empirical study by taking Bishan District as an example. The results indicated that： ① Based on the results of comprehensive risk assessment， among the large-scale cultivation plots in Bishan District， （20 25.82% were at high risk， 24.07% were at medium risk， 23.01% were at low risk，and 11.59% were at extremely high risk. ② Regarding the risk assessment of each dimension， the source indicators were mainly risk-free，the flow indicators were mainly at a medium risk，and the sink indicators were mainly at a high/extremely high risk. Based on the“source-flow-sink” approach， targeted countermeasures and suggestions were put forward to provide theoretical and practical guidance for improving the risk control system of non-point source pollution in the planting industry.
