Drinking water source environment risk source background list determining and updating method and device

Abstract

The invention discloses a drinking water source environment risk source background list determining and updating method and device, and belongs to the field of water source monitoring. Satellite remote sensing information and field information are fused to obtain updating data of the water source environment risk source, a water source environment risk source background list is automatically updated, a real risk source list is formed, and the list can be used for water source environment improvement, field law enforcement and field supervision. On one hand, the advantages of wide satellite remote sensing thematic information coverage and accurate spatial positioning are fully exerted, time and labor are saved, and on the other hand, the advantage that various attribute information and on-site photos of a risk source are convenient to collect during on-site checking is exerted. The real risk source comprehensively reflecting the water source situation can be generated, the water sourceglobal situation is comprehensively reflected, the risk source data acquisition difficulty and cost are lower, the timeliness is good, the convenience, economy and authenticity of water source environment risk source acquisition are improved, and the invention is a problem list capable of being used for water source environment law enforcement and environment supervision.

Description

technical field [0001] The invention relates to the field of water source monitoring, in particular to a method and device for determining and updating a background list of environmental risk sources of drinking water sources. Background technique [0002] Solving the outstanding environmental problems of drinking water sources is the primary task of the environmental protection of drinking water sources in my country. The list of risk sources that can be used for environmental law enforcement management is the starting point for water source protection and the basic data to ensure the protection effect. There are two ways to form the list of environmental risk sources: the first is that administrative units report the information level by level based on on-site information; the second is the problem list based on satellite remote sensing extraction. [0003] The accuracy of the list of environmental risk sources of water sources formed by administrative units based on on-si...

Problems solved by technology

However, due to the large area and remote location of the drinking water source protection area, it is difficult to find small-scale "small scattered sewage" enterprises and sewage outlets that are not on the list in the entire water source area. Such environmental problems, usually not comprehensive checklist

Therefore, the information on the "point" of the "point" information expressed by the administrative unit based on the on-site information and the level-by-level reporting of the risk source list is relatively accurate, and the information on the "surface" is difficult to fully cover, and the timeliness is poor, the cost is high, and the objectivity is poor. comprehensiveness cannot be guaranteed

[0004] The list of risk sources extracted based on satellite remote sensing can take into account the information on the surface of the water source protection area, but it is limited by the fact that the remote sensing images cannot see the inside of the target, resulting in misjudgment of some information categories, or some pollution management information It is not reflected in satellite images, that is, remote sensing information has the characteristics of "easy to locate but difficult to determine".
