Environmental risk zoning-based decision support method for layout optimization adjustment

Abstract

The invention provides a combined application method of regional environmental risk assessment zoning, regional environmental risk bearing capacity and a GIS (geographic information system) platform with intuitiveness, accuracy and a wide application range for the regional layout optimization and adjustment according to the status of the current environmental risk control and management techniques, which aims at that the basis for the adjustment and the optimization in the current regional layout optimization and adjustment is short of a theoretical and quantitative basis. The method comprises the following steps: gathering environmental risk bearing capacity assessment index data according to the proposed environmental risk bearing capacity-based conception and a quantification method, calculating the environmental risk bearing capacity of researching regions, and realizing the display of the spatial distribution of the environmental risk bearing capacity through the GIS platform; analyzing risk sources in the regions, analyzing the positions of the risk sources, and the species and the stored quantity of risk materials of the risk sources, carrying out assessment on the degree of contamination and the range of influence on the atmosphere and water bodies caused by the leakage of pollutants according the improved Gaussian model and the pollutant-water body one-dimensional diffusion model so as to obtain the risk fields of the risk sources, and equally realizing the display of the spatial distribution of the risk fields through the GIS platform; carrying out superposition on the regional environmental risk bearing capacity and the regional environmental risk fields in a GIS, and realizing the conflict analysis of regional environmental risk-risk bearing; and proposing an adjustment scheme for regions with risk-bearing conflicts according to the rules of the layout optimization adjustment.

Description

technical field [0001] This patent involves the fields of environmental risk assessment, vulnerability assessment, and environmental carrying capacity, especially a combined application method of "regional environmental risk assessment zoning + regional environmental risk carrying capacity + GIS platform", which is widely applicable to the layout of regions of different scales Optimize the adjustment process. Background technique [0002] With the advancement of industrialization and urbanization, sudden environmental pollution accidents occur frequently in our country, with increasing impact and losses, which have become an important factor that hinders regional economic development and threatens environmental safety and human health. The rise of a large number of chemical industry parks has greatly increased the probability of environmental pollution while stimulating the rapid development of China's economy. At the same time, my country's population continues to grow and...
