Marine ecological red line water quality up-to-standard judgment method and device

Abstract

The invention discloses a marine ecological red line water quality up-to-standard judgment method and device, and belongs to the field of sea water quality monitoring. The method comprises the steps of performing interpolation calculation according to the acquired water quality index of each site, to acquire a water quality index spatial distribution map of a whole area, and clipping by using a sea ecological red line boundary vector to acquire a water quality index spatial distribution map of a sea ecological red line range; performing water quality classification on each interpolation pointin the water quality index spatial distribution map of the sea ecological red line range according to a seawater quality evaluation standard, to acquire spatial distribution maps of different water quality categories; calculating the area of the spatial distribution maps of different water quality categories, and computing a proportion of the spatial distribution area of different water quality categories in the sea ecological red line area; and judging whether the sea red line water quality is up to the standard according to the proportion. According to the method and device, the defect thatin traditional methods, water quality of the single site cannot accurately reflect the whole condition of the surrounding seawater quality is avoided, and the whole water quality condition of the seaarea is reflected to a certain extent.

Description

technical field [0001] The invention relates to the field of marine water quality monitoring, in particular to a method and device for judging that the water quality of the marine ecological red line reaches the standard. Background technique [0002] At present, with economic development, affected by multiple factors such as coastal development, population concentration, and heavy resource and environmental loads, the pressure on marine ecosystems is becoming increasingly significant. Monitoring shows that, due to lack of effective protection of marine ecosystems in some regions, there is a trend of degradation of ecological functions and a decline in the quality of the ecological environment. In order to maintain national ecological security and promote the sustainable development of coastal society and economy, my country has established a marine ecological red line system. [0003] The marine ecological red line, also known as the marine red line area, refers to the are...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a method and device for determining whether the water quality of the marine ecological red line reaches the standard. The present invention can avoid the defect that the water quality of a single station in the traditional method cannot accurately reflect the overall condition of the surrounding sea water quality, and to a certain extent reflects the water quality of the sea area. overall water quality
