A method for optimizing location of water source based on environmental risk avoidance

Abstract

The invention discloses a method for optimizing location of water source based on environmental risk avoidance, belonging to the field of environmental science and environmental risk technology, and comprising the following three steps of step 1 calculating the size Si of each risk source around the drinking water source and the accident occurrence probability Pi to obtain the risk value Rsi of the risk source; 2 based on that risk value of the risk sources, combining with the accident harm degree, using the software ArcGIS 10.2, adopting the inverse distance weight interpolation method to construct the risk equivalent distribution map of the drinking wat source; 3 dividing that risk grade of the drinking water source area, and proposing an optimized location scheme of the water source area or an environmental risk source adjustment scheme according to the risk avoidance principle. The method for optimizing location of the water source based on environmental risk avoidance comprehensively considers the size of risk source, the accident occurrence probability and the harm degree, and constructs an environmental risk assessment and risk avoidance method of water source, is beneficialto avoiding uncertainty of subjective judgment and provides the technical support for guaranteeing water supply safety of water source.

Description

technical field [0001] The invention belongs to the technical field of environmental science and environmental risk, and in particular relates to a method for optimal site selection of water sources based on environmental risk avoidance. Background technique [0002] Water is the source of life, the key to production, and the foundation of ecology. Drinking water safety is directly related to public health and to sustainable economic and social development. Guaranteeing and providing safe drinking water has become the focus of attention of all walks of life and governments at all levels. Lakes and rivers are the main sources of drinking water in my country. Maintaining water quality safety and ecological health of rivers and lakes is the basis for ensuring drinking water safety. [0003] In recent years, with the rapid development of social economy and the intensification of human activities, the density of pollution sources around water sources has gradually increased, and...

Problems solved by technology

The development and utilization layout of some water source shorelines is unreasonable. There are piers, chemical enterprises, and high-tech industrial development zones on the upstream and downstream shorelines, and waste water is discharged through sewage outlets or rainwater mixed discharge outlets to form pollution zones, directly threatening the water supply safety of water source areas. At the same time, it restricts the development and utilization of local good coastlines

[0004] At present, research on the optimal layout of drinking water sources under the background of high-intensity shoreline development is still in its infancy. Most of the risk assessments of water sources at home and abroad focus on calculating the direct risk of pollution sources affecting the water quality of water sources. The relevant technical means need to be further developed. promote
