System and method for evaluating ecological health risk of water environment

Abstract

The invention discloses a system for evaluating the ecological health risk of a water environment, and the system comprises an evaluation index building unit which is used for building an evaluation index system, which comprises a plurality of evaluation indexes, of the water environment; a weight calculation unit which is used for calculating the weights of the evaluation indexes; an informationinput unit which is used for generating and evaluating the inherent quantification standard information of the water environment according to the evaluation index system; a data collection unit whichis used for collecting and evaluating the variable quantification standard information of the water environment according to the evaluation index system; and an evaluation management unit which is used for determining a main factor and a main factor influence threshold value of the water environment according to the weights of the evaluation indexes and the evaluation information of the information put unit and the data collection unit for the evaluation index system, and evaluating the ecological health degree of the water environment. The system achieves the sharing of the information of thewater environment, achieves the comprehensive management of the factors affecting the water environment, and gives evaluation advice for each water environment. The invention also discloses a methodfor evaluating the ecological health risk of the water environment.

Description

technical field [0001] The invention relates to the technical field of water environment safety, in particular to a water environment ecological health risk assessment system and method. Background technique [0002] The socioeconomic system of a city depends on various functions provided by urban rivers, such as receiving functions, ecological functions, landscape and beautification functions, etc. Therefore, a healthy urban water environment is an important guarantee for urban sustainable development. However, with the rapid development of my country's economy and the continuous improvement of people's living standards, the discharge of industrial and agricultural wastewater and domestic sewage has increased year by year, causing serious pollution to urban rivers. [0003] At present, cities across the country have carried out in-depth management of rivers and lakes, and achieved certain results. However, the governance of the water environment is not a periodic work, bu...

However, the governance of the water environment is not a periodic work, but a continuous work

In the existing technology, the ecological elements such as water quality in each area are generally monitored separately, but the ecological health of the water environment cannot be evaluated as a whole.
