Problems solved by technology

There are many methods to determine the "water level" in the traditional groundwater research field, including: groundwater seepage numerical model method, gray prediction model method, time series prediction method, regression analysis method, water balance method, etc., but few involve how to determine the "control water level" , and for different groundwater development and utilization goals, the goal of "controlling water level" will be different, and the constraints for realizing "controlling water level" will also be different

Embodiment

[0083] Example: Taking Tianjin as an example, this method is used to determine the groundwater control water level.

[0084] Step 1: Division of groundwater functional areas:

[0085] The groundwater functional zones of Tianjin are divided into deep and shallow groundwater functional zones. Tianjin's groundwater primary function zone is divided into three categories: development zone, protection zone and reserved zone. Within the framework of the groundwater primary functional area, it is divided into five types of groundwater secondary functional areas. Among them, the development zone is divided into centralized water supply source area and decentralized development and utilization area, and the protected area is divided into ecological fragile area and geological disaster-prone area without groundwater water conservation area (groundwater water source conservation area refers to the area where important springs are gushed to a certain extent. There are no groundwater sour...

Abstract

The invention discloses a method of determining an underground water controlled water level by utilizing risk evaluation. The method comprises the steps of partitioning underground water functional zones; selecting natural factors and social and economic factors, which influence the development and utilization of underground water, of the underground water; determining the weight of each factor of each functional zone by adopting an AHP (Analytic Hierarchy Process); calculating the risk value of each water-bearing stratum of each function division and the corresponding risk grade by utilizing a comprehensive evaluation method; determining corresponding underground water level values under different risk grades. The method is capable of providing a scientific basis for the reasonable development and utilization and the programme of the regional underground water, and the practicability is stronger.

Description

technical field [0001] The invention relates to a method for determining the controlled water level of groundwater, specifically, a method for determining the controlled water level of groundwater by using risk assessment. Background technique [0002] "Water level" is of great significance and role in the field of groundwater. It is a key indicator for hydrogeological calculation and groundwater resource evaluation, and a key factor affecting the groundwater environment. It has always been one of the main contents of groundwater technical work. With the increasing complexity of groundwater management issues, around 2007 some scholars proposed the concept of "dual management" of groundwater level and water volume; by 2012, the State Council's "Opinions on Implementing the Strictest Water Resources Management System" (Guofa [2012] No. 3), in "Strict groundwater management and protection", it is clearly proposed to "strengthen the dynamic monitoring of groundwater, implement t...
