Embodiment Construction

[0024] The application will be described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific embodiments are only used to further illustrate the application, and cannot be interpreted as limiting the protection scope of the application. The above application content makes some non-essential improvements and adjustments to this application.

[0025] combine figure 1 and figure 2 As shown, a GIS-based agricultural non-point source pollution prevention and control method, the steps include:

[0026] Step 1. Subdivide the prevention and control area into several subdivision areas. In each area, the data acquisition module obtains the field dynamic data in each subdivision area. The field dynamic data includes the number of domestic waste disposal points, human and animal excrement Data on the number of discharge points, the number of inhalable particulate matter in the air, the number of bacteria in wat...

Abstract

The invention discloses an agricultural non-point source pollution prevention and control method based on a GIS, comprising the following steps of: carrying out the subdivision of a prevention and control region, obtaining on-site dynamic data in each subdivision region, and transmitting the on-site dynamic data to a control center; comparing and calculating the field dynamic data with standard limit data stored in a database module to obtain a pollution index of each subdivision region, and sending pollution alarm information through an alarm module when the pollution index is higher than a threshold value; calling geographic information in a GIS system module, associating the pollution alarm information with the geographic information, and providing corresponding prevention and control measures; and calling coordinate information of prevention and control facility points in the GIS system module, associating prevention and control measures with the coordinate information of the prevention and control facility points, analyzing and selecting the optimal prevention and control facility point, and notifying personnel of the prevention and control facility point to adopt corresponding facilities to perform pollution prevention and control. The method is based on the GIS technology, and the current situations that at present, agricultural non-point source pollution is serious, andthe prevention and control measure effect is poor are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural pollution prevention and control, in particular to a GIS-based agricultural non-point source pollution prevention and control method. Background technique [0002] Rural non-point source pollution refers to dissolved or solid pollutants in rural life and agricultural production activities, such as soil particles, nitrogen, phosphorus, pesticides and heavy metals in farmland, and rural livestock manure. Organic or inorganic substances such as domestic garbage, from non-specific areas, under the action of precipitation and runoff, through farmland surface runoff, farmland drainage and underground seepage, a large number of pollutants enter the receiving water body (rivers, lakes, reservoirs, Bay) caused by pollution. Agricultural non-point source pollution has the characteristics of dispersion, concealment, randomness, uncertainty, difficulty in monitoring, and spatial heterogeneity. Seriousl...
