Abstract

This paper uses the analytic hierarchy process (AHP) as the basic framework, and evaluates the water environment risk management technology of the river basin in Liaoning Province, so as to scientifically and reasonably measure the advantages and disadvantages of the existing technology.The research results show that the best technical indicator is the research management technology of water environment quality monitoring technology; the best environmental indicator is the management technology of the research project of water quality safety assessment and early warning management technology in the basin. The highest overall score is the water environment quality monitoring technology method research management technology. Each management technology has certain advantages, and the management technology should be used jointly.

Highlights

The Liao River Basin is one of the areas in China where cities are concentrated, densely populated, and socially and economically developed
The main constraints of development [1].Risk assessment is to identify and measure the possible loss of human health, social and economic development, ecosystems, etc. caused by or faced by various human development activities. It includes sudden water environment risk assessment and cumulative water environment risk assessment [2].Sudden water pollution accidents mainly refer to accidents caused by accidents, where a large amount of pollutants enter the water body in a short time, which causes rapid deterioration of water quality, affects the effective use of water resources, seriously affects normal economic and social activities, and destroys the water ecological environment
In order to achieve the quantification of various evaluation indicators, with the help of fuzzy mathematics theory and the use of membership functions, the standardized evaluation values of various indicators of risk management technology are obtained.According to the risk management technology evaluation index system constructed in the previous article and the determined weights of each evaluation index, a comprehensive technology-environmental assessment of the risk management technology is carried out

Summary

Introduction

The Liao River Basin is one of the areas in China where cities are concentrated, densely populated, and socially and economically developed. Cumulative environmental risk means that after long-term accumulation of trace pollutants in human development activities to a certain extent, it will produce rapid ecosystem degradation or cumulative toxic effects, and endanger human health[3]. This risk has no obvious manifestation in the short term, but it has a long-term impact on human health and ecological security [4]
