Area integrated environment risk evaluation and portioning method

Abstract

The invention provides an area integrated environment risk evaluation and portioning method, for reflecting the environment risk status of an area. The method comprises the following steps: obtaining area environment risk correlation information, and according to an area integrated environment risk system theory, through combination with the obtained area environment risk correlation information, constructing an area integrated environment risk evaluation index system, wherein the index system comprises a risk source harm index, a risk field intensity index, a risk acceptor vulnerability index and a risk control mechanism validity index; determining an index weight and quantification model of the index system; according to the determined index weight and quantification model of the index system, obtaining an area integrated environment risk index; and according to the area integrated environment risk index, performing risk partitioning on the area so as to obtain an area integrated environment risk partitioning graph. The method provided by the invention is applied to the field of environment science and environment risks.

Description

technical field [0001] The invention relates to the field of environmental science and environmental risk, in particular to a regional comprehensive environmental risk assessment and zoning method. Background technique [0002] In the existing environmental risk assessment studies, generally only a single risk factor (such as polycyclic aromatic hydrocarbons) or a single risk source (such as industrial or agricultural sources) is considered, and risk transmission and control are not considered. As far as the whole country is concerned, environmental risk assessment is far from just considering a single factor, often a combination of multiple factors. [0003] In 2012, the Ministry of Environmental Protection of China announced the highly polluting industries in 13 sensitive areas in the country, and strictly restricted their development because of the high risk of air pollution in the areas where these industries are located. Most environmental risks have obvious regional c...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a regional comprehensive environmental risk assessment and zoning method to solve the problem that the regional environmental risk assessment object in the prior art is limited to individual chemical agents or a small area for a certain polluted site. There is no comprehensive environmental risk assessment from a large regional scale, and the existing regional comprehensive environmental risk assessment index system only considers the problem of two to three factors in risk sources, risk fields, risk receptors and risk control mechanisms
