Problems solved by technology

[0004] With the expansion of the risk assessment scale, the traditional conceptual model can no longer meet the early warning and assessment requirements involving multiple risk sources, multiple pressure factors, and multiple risk impacts at the regional level, and various factors need to be considered comprehensively

Embodiment Construction

[0033] The chemical industry in Lianyungang has developed rapidly in recent years. Regional chemical parks are concentrated. By the end of 2008, there were nearly 10 chemical industrial parks above the provincial level in Lianyungang. The construction of emergency systems for centralized processing facilities in these parks has just started, and technology, talents, and funds are relatively lacking. A large amount of industrial wastewater rich in N, P, COD and other pollutants discharged from the park, as well as toxic and harmful gases such as HCL and benzene, as well as persistent organic pollutants (POPS) have long-term and potential impacts on the regional environment. Sewage discharged from chemical production generally has the characteristics of harmfulness, aerobicity, acidity and alkalinity, eutrophication, oil coverage, high temperature, etc.; chemical waste gas is flammable, explosive, toxic, irritating, corrosive, Dust and other characteristics; the pollution of th...

Abstract

The invention provides a method for determining a regional ecological risk early warning, which belongs to the field of ecological risk protection. The method comprises the following steps of: determining regional ecological risk composite indexes; sending an early warning of the regional environmental risk state according to the regional ecological risk composite indexes; and determining a bad state early warning and a regional environmental risk trend early warning to further determine a slow deterioration early warning and a rapid deterioration early warning. Based on remote sensing investigations of a researched region environmental element, the method constructs a regional ecological risk assessment index system for determining how to adopt the regional ecological risk early warning by combining the characteristic of regional industrial development stress, considering the characteristics of a risk source, receptor sensitivity and the like, and using the theories and methods such as system dynamics, landscape ecology, GIS analysis, AHP and Delphi. The method provides a scientific basis and a support for regional ecological risk management.

Description

technical field [0001] The invention relates to a method for determining regional ecological risk, more specifically a method for determining early warning of regional ecological risk. Background technique [0002] In recent years, a large amount of industrial wastewater rich in N, P, COD and other pollutants discharged from Gelei Industrial Park, especially the chemical industry park, as well as toxic and harmful gases such as HCL and benzene, as well as persistent organic pollutants (POPS) have long-term effects on the regional environment. , Potential impact. Sewage discharged from chemical production generally has the characteristics of harmfulness, aerobicity, acidity and alkalinity, eutrophication, oil coverage, high temperature, etc.; chemical waste gas is flammable, explosive, toxic, irritating, corrosive, Dust and other characteristics; the pollution of the environment by waste residues in the chemical production process on the soil waters and the atmosphere has al...
