Abstract

The invention discloses a drinking water source land environment risk assessment method, belongs to the technical field of drinking water source land environment risk assessment, and solves the problems that an existing drinking water source land environment risk assessment method is not objective or comprehensive enough and cannot comprehensively reflect the drinking water source land environmentrisk condition of southern highly developed cities. The invention relates to a drinking water source area environment risk assessment method, which comprises the following steps of: 1, selecting evaluation indexes according to a Delphi method in combination with the actual investigation condition of a water source area according to the existing research result and case analysis; 2, establishing an analytic hierarchy process model of the evaluation indexes by utilizing an analytic hierarchy process and data obtained by research and investigation, and calculating and determining a weight valueof each evaluation index; and 3, according to the actual situation of the influence of each index on the environment of the drinking water source area, assigning a score to each index by adopting a quartering principle. 4, calculating a weighted average value of each index, and solving a risk score; and finally, according to existing research results and case analysis, risk level grades are divided in combination with reality.

Description

technical field [0001] The invention discloses a drinking water source environmental risk assessment method, which belongs to the technical field of water source environmental risk assessment. Background technique [0002] Water is the source of life. Biological survival cannot be separated from water, and people's daily production and life cannot be separated from water. This shows the importance of water resources. Therefore, it is particularly important to do a good job in the environmental risk assessment of drinking water sources in order to better protect the environment of water sources and ensure water safety. [0003] There are also many assessment methods for the environmental risks of drinking water sources, but these methods often assess the environmental risks of industrial production or road transportation production in the environment of drinking water sources, and the assessment results are not comprehensive and objective enough to be comprehensive. reflect ...
