[0007] Since there is no uniform definition of the concept of vulnerability and its elements, there is no patent that systematically summarizes the vulnerability assessment of environmental risk receptors and formulates it into a complete method system. With the frequent occurrence of environmental pollution accidents , the impact

Embodiment 1

[0018] The population density and economic density of an area are high, and the environmental risk sources are mainly distributed in areas along the river, chemical industry parks and densely populated areas, and the sensitive ecosystems are mainly distributed in the suburbs and other areas with few environmental risk sources. The vulnerability evaluation index system of environmental risk receptors is constructed. As shown in Table 1, the vulnerability of receptors is evaluated from two aspects of socio-economic and ecological environment. Finally, the comprehensive vulnerability of environmental risk receptors in the research area is obtained based on the GIS platform. sex distribution map.

[0019]Due to the extremely high socio-economic vulnerability and ecosystem vulnerability in the densely populated area of ​​the city center and the upstream of the drinking water source, the comprehensive vulnerability of the environmental risk receptors in this area is relatively high, ...

Abstract

The invention provides a method for evaluating the vulnerability of regional environmental risk receptors based on multi-index and spatial visualization technology. The method includes the following three steps: first, select the sensitivity and adaptability of the exposed receptors, and construct the vulnerability index model of the regional environmental risk receptors; According to the vulnerability evaluation index of environmental risk receptors, regional socio-economic vulnerability and ecosystem vulnerability are evaluated; finally, based on GIS technology, the layers of regional socio-economic vulnerability and ecosystem vulnerability are directly superimposed or The weighted superposition calculation is used to obtain the distribution map of the comprehensive vulnerability index of the regional environmental risk receptors. This evaluation method is widely used in regional environmental risk management, industrial layout optimization and adjustment, etc., and has the characteristics of high efficiency, low cost, and high precision.

Description

technical field [0001] The invention relates to the fields of environmental science, environmental risk and environmental management, in particular to a method for comprehensively evaluating the vulnerability of regional environmental risk receptors by using multiple indicators and spatial visualization technology. This evaluation method is widely used in the optimization and adjustment of regional industrial layout, land use planning and biodiversity protection planning, and environmental risk emergency management. Background technique [0002] In recent years, due to the increase in the production, storage and transportation of hazardous substances in chemical companies, environmental pollution accidents have occurred frequently in our country, and the social economy and the ecological environment are facing great threats. Relevant statistics show that: from 1990 to 2008, my country's environmental pollution accidents have caused 28 deaths and 53,966 people's health has be...
