Problems solved by technology

[0008] The purpose of the present invention is to provide a three-dimensional zoning method and application method for groundwater environmental functions of Quaternary multi-aquifers based on GIS (Geographic Information System or Geo-Information system, referred to as GIS) zoning, so as to solve the problems of Quaternary groundwater environmental functions. The problem of zoning methods and the application method of groundwater environmental function areas in resource and environmental protection have led to the ambiguity of the current groundwater protection goals and protection methods. In the development and utilization of groundwater resources, there are mixed-layer exploitation, waste of high-quality groundwater resources, and resource utilization. Unreasonable allocation, poor sustainability and other key technical problems in environmental issues, and at the same time, lay the foundation for groundwater classification, stratification, zoning, quality protection and sustainable use of water resources

Embodiment 1

[0098] Example 1: The applicant carried out groundwater environmental functional zoning in a certain multi-layered groundwater aquifer area in a certain city in North China: the details are as follows:

[0099] S1. According to the above-mentioned delineation method of groundwater environmental function zones, the Quaternary multi-aquifer group is divided into three-dimensional groundwater environmental functions, and it is divided into four aquifer groups from top to bottom.

[0100] S2, according to the structure of the groundwater aquifer in this area, the Quaternary groundwater aquifer is divided into 1-4 aquifer groups.

[0101] The first aquifer group is divided into four types of groundwater environmental functional areas from Ⅱ to Ⅴ levels.

[0102] The second aquifer group is divided into three types of groundwater environmental functional areas, grades II-IV.

[0103] The third aquifer group is divided into three types of groundwater environmental functional areas, ...

Embodiment 2

[0111] Embodiment 2: Carry out the specific application of groundwater environmental functional zoning to guide the protection of groundwater in a certain city for the above-mentioned multi-layer groundwater aquifer area:

[0112] ① In order to meet the needs and requirements of groundwater environmental management in a certain city, the second-level environmental function zoning can be carried out on the basis of the first-level environmental function zoning according to the main functions of the region, the current water quality compliance, the relationship between the over-standard factors and the location of the protected area, etc. Based on the results of groundwater environmental function zoning, comprehensively analyzing the causes of water quality exceeding the standard and the current groundwater function, determine the short-term and long-term target water quality of groundwater in each environmental function zone, so as to carry out hierarchical and zonal monitoring o...

Abstract

The invention discloses a method and an application method of quaternary multi aquifer groundwater environmental function zoning. The method and the application method mainly aims at groundwater environmental functions three-dimensional zoning in plain areas with quaternary groundwater system multiple aquifers. The specific methods are as following of: S1, clearing and defining the spatial distribution of the aquifer group groundwater area and phreatic layer and confined aquifer. S2, according to the current water quality restriction index, aiming at the current situation water quality standard area of the multi-layer aquifer group, carrying out the preliminary delimitation of the environmental functional area according to the current situation water quality; S3, limiting indexes accordingto the current status of the water body of the underground water; S4, for the water quality non-compliance area outside the water source protection area, carrying out comprehensive scoring accordingto the weight quantitative indexes; from the shallow to the deep, the groundwater of each aquifer in the quaternary in the plain area is partitioned in sequence. The method is applied to the classification, grading, zoning and control of the groundwater pollution source in the water source protection area by the environmental protection department, and guides the planning department to carry out the unified industrial layout and planning.

Description

technical field [0001] The invention relates to the technical field of environmental impact assessment and groundwater function zoning, in particular to a three-dimensional zoning method and application method for groundwater environmental functions in multiple aquifers of the Quaternary system. Background technique [0002] As an important water body on the earth, groundwater has stable water supply conditions and good water quality. It is an important water source for agricultural irrigation, industrial and mining enterprises, and cities, and is also an essential water resource for human society. Especially in arid and semi-arid areas where surface water is scarce, groundwater often becomes the main source of local water supply. [0003] In northern my country, especially in the North China Plain, groundwater is an important source of water supply. However, due to over-exploitation, the groundwater resources in the North China Plain have been depleted year after year, and...
