Problems solved by technology

The results of the two calculations will have a big difference
[0009] Generally speaking, although domestic scholars and governments have gradually realized the importance of groundwater pollution prevention and control, the previous work mainly focused on the vulnerability of groundwater, and the identification and assessment of groundwater pollution risks is still in its infancy, especially when surface pollution sources, Pollution risk identification and assessment of human disturbance, surface water, etc. There is no relevant research report yet

Embodiment 1

[0078] The following embodiment is a comparatively preferred embodiment of the groundwater vulnerability and pollution risk assessment method in the plain river network area of ​​the present invention, which is only used as a preferred method to further elaborate on the thinking of the present invention, rather than as a specific protection of the present invention limited understanding of the scope. Those skilled in the art should understand that, especially the classification or weighting calculation method involving risk, it can be calculated based on machine learning methods such as neural networks and model building based on historical data, and will not be repeated here.

[0079] 1. Establish groundwater vulnerability model

[0080] The model includes 7 parameters, namely the buried depth of groundwater table (D), net recharge (R), aquifer medium (A), soil zone medium (S), topography (T), vadose zone medium (I), For the hydraulic conduction system (C), for seven differe...

Embodiment 2

[0193] In addition to the above-mentioned embodiment 1, the present invention also provides a groundwater vulnerability and pollution risk assessment system in the plain river network area, which can be combined with the groundwater vulnerability in the plain river network area in the above-mentioned embodiment 1 and pollution risk assessment methods, the system includes:

[0194] The index data entry module is used to enter various index data, and the index data includes the essential vulnerability index data of the groundwater environment, the special vulnerability index data of the groundwater, and the pollution source load risk index;

[0195] The grading module is used to pre-store groundwater pollution risk level grading data, pollution source load grading data, and groundwater environmental essential vulnerability index grading data;

[0196] The groundwater pollution risk calculation module is used to calculate the groundwater pollution risk prevention and control valu...

Abstract

The invention provides a method and system for assessing underground water vulnerability and pollution risks in a plain river network area. The system comprises an index data input module, a grading module, an underground water pollution risk computation module and a display module, wherein the index data input module is used to input various types of index data; the grading module is used to pre-store grading data of underground water pollution risk grades, grading data of pollution source loads, and grading data of underground water environment essential vulnerability indexes; the underground water pollution risk computation module is used to compute an underground water pollution risk prevention and control value according to the various types of index data and compute a risk grade of the area corresponding to the underground water pollution risk prevention and control value in combination with the grading data of the underground water pollution risk grades in the grading module; and the display module is used to edit computation results of the underground water pollution risk computation module into pictures for display in combination with GIS data. The system is characterized in that the new vulnerability computation method is used; direct display is achieved effectively in combination with GIS information; and practicability is greatly enhanced.

Description

technical field [0001] The invention relates to a modeling and calculation method for calculating groundwater vulnerability and pollution risk in a specific area, in particular to a groundwater pollution risk calculation method based on groundwater vulnerability calculation and pollution analysis in plain river network areas. Background technique [0002] Groundwater resources are important strategic resources supporting sustainable economic and social development. The amount of groundwater resources in my country accounts for about 1 / 3 of the total water resources in the country. With the development of society and economy, the environmental pressure of groundwater is gradually increasing, and the situation of groundwater pollution is becoming more and more serious. The problem of groundwater pollution in some areas is prominent. According to the results of the "New Round of National Groundwater Resources Evaluation" by the Ministry of Land and Resources from 2000 to 2002, ...
