Rice field non-point source pollution monitoring method

Abstract

The invention provides a rice field non-point source pollution monitoring method, which comprises the steps of dividing a target area into N target sub-areas, and recording a flow direction between two adjacent target sub-areas, wherein N is a positive integer, and N is greater than or equal to 2, monitoring positions in the M target sub-areas, wherein M is a positive integer, and M is smaller than N, according to a preset period, obtaining a monitoring sample of a target sub-area where the monitoring position is located at each monitoring position, and when the pollution index of the monitoring sample is greater than or equal to a preset threshold, acquiring corresponding monitoring samples from one or more target sub-areas with the flow direction of the target sub-area relative to the monitoring position being the forward flow direction, wherein the forward flow direction is used for indicating the diffusion direction of the rice field water system. The problem that the non-point source pollution in the rice field cannot be effectively monitored in the prior art can be solved, so that the non-point source pollution in the rice field is effectively monitored, and the correspondingtreatment effect is further realized.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a method for monitoring paddy field non-point source pollution. Background technique [0002] Non-point source pollution Dissolved and solid pollutants flow into the receiving water body through the runoff process from non-specific locations under the action of precipitation erosion and cause water eutrophication or other forms of pollution. Compared with point source pollution, non-point source pollution is mainly composed of surface soil sediment particles, nutrients such as nitrogen and phosphorus, harmful substances such as pesticides, solid waste such as straw and agricultural film, livestock and poultry breeding feces and sewage, aquaculture bait and medicine, rural areas Domestic sewage and garbage, various atmospheric particulate matter settlements, etc., are caused by entering the water body environment through surface runoff, soil erosion, and farmland drainage. ...
