Problems solved by technology

The layout of monitoring points in the origin of agricultural products is different from the soil pollution investigation and prevention work carried out by the departments of environmental protection and land resources. It not only needs to consider the actual situation of the origin of agricultural products, soil type, land use status, crop distribution, but also the pollution sources around the origin. Therefore, the small-scale method such as 8km×8km adopted by environmental protection and enviro

Example Embodiment

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0026] A method for laying out soil monitoring points in agricultural product production areas based on step-by-step grid refinement, the steps are as follows:

[0027] ⑴Determine the scope of the monitoring area of ​​the origin of agricultural products, and collect the administrative division map and land use map of the target area;

[0028] (2) In the geographic information system, the administrative division map and land use map of the target area are superimposed, and the layers of villages, rivers, roads, ponds and other layers are loaded at the same time. The layer of the layer is evenly divided into multiple square grids as the initial grid;

[0029] The initial grid is a 2km×2km square grid,...

Abstract

The invention discloses an agricultural producing area soil monitoring point arrangement method based on step-by-step grid refinement. The method comprises the steps of collecting the administrative map and land use map of a target area; distributing initial grids, looking for and refining monitoring points, arranging the monitoring points one by one till a monitored target agricultural producing area is covered by the monitoring points according to the land use type and a step-by-step refined grid, and forming an agricultural producing area soil preset monitoring point distribution diagram. According to the method, basic maps or drawings and the GIS space analysis technique are fully utilized, blindness during agricultural producing area soil monitoring point arrangement and sampling is reduced, accuracy, representativeness and scientificity of agricultural producing area soil monitoring point arrangement are improved, and operation and implementation are made easy for basic sampling personnel.

Description

technical field [0001] The invention relates to a grid-by-level refinement-based soil monitoring point layout method and application of agricultural product production areas, belonging to the fields of soil science and environmental science. Background technique [0002] The origin of agricultural products is the source of agricultural product production, which directly affects the quality and safety of agricultural products produced there. Since the 1980s, the pollution of agricultural production areas in my country has become increasingly serious, and the area of ​​farmland affected by pollution has increased significantly, showing a trend of spreading from local to overall. The safety and quality of agricultural products have declined due to environmental pollution in the place of production of agricultural products, and some agricultural products have exceeded pollution standards from time to time. The "Agricultural Product Quality and Safety Law" and the "Agricultural ...
