specific Embodiment

[0065] An embodiment of the present invention provides a method for quickly processing a non-point source pollution discharge inventory, which specifically includes the following steps:

[0066] Step 1, import the vector map of the watershed boundary (see figure 2 ), automatically determine the dimension of the centerline of the watershed, and use the dimension of the centerline to judge whether the watershed belongs to the southern area or the northern area (see image 3 ), and identify the upper, middle and lower reaches of the watershed (see Figure 4 ),from image 3 It can be seen that the basin is located in the northern area.

[0067] Step 2: Using the national administrative division map and the national land use type map, according to the area where the watershed is located, the area of ​​each land use type of each administrative division in the watershed is obtained, and the non-point source output of the national framing plot is used Coefficient lookup table, acc...

Abstract

The invention discloses a method for quickly processing a non-point source pollution emission inventory and relates to the technical field of watershed pollution prevention and control. According to the method, non-point source pollution data is standardized into a watershed scale, difference between data generated by pollution in a north area and a south area, as well as difference between data generated by seasonal pollution are comprehensively considered, the compiling efficiency and the scientificity of a pollution source emission inventory are improved, and the emission reduction measures and the emission reduction benefit of the non-point source pollution are analyzed by a technical method, so the method has wide application prospect in the aspects of total quantity control, energy conservation and emission reduction when being applied to the watershed pollution prevention and control.

Description

technical field [0001] The invention relates to the technical field of river basin pollution prevention and control, in particular to a method for quickly processing a non-point source pollution discharge inventory. Background technique [0002] Compiling a "quantifiable, measurable, and verifiable" pollutant discharge inventory is a demanding and difficult systematic and dynamic project, which must rely on a good compilation mechanism. [0003] At present, in order to grasp the discharge of non-point source pollution in the river basin in a timely manner, further control the discharge level, and achieve the purpose of improving the quality of the water environment, my country has focused on investigating farmland pollution, domestic pollution, and livestock and poultry breeding pollution in the national pollution source census and environmental statistics. The amount of production and emissions consumes a lot of manpower, material and financial resources. [0004] However, ...
