Method for building apparent pollution classification model of landscape water body and apparent pollution classification method of landscape water body

Abstract

The invention discloses a method for building an apparent pollution classification model of a landscape water body and an apparent pollution classification method of the landscape water body. The method for building the landscape water body apparent pollution classification model comprises the following steps: firstly, defining different apparent pollution types; selecting sampling points according to definition and carrying out water sample collection and determination as well as data accumulation; performing inductive analysis on accumulated data quantity by adopting a statistical method based on various index theory analysis; identifying different apparent pollution type characteristic indexes or characteristic values; determining the different apparent pollution type characteristic indexes and ranges of thresholds of the indexes; secondly, building the classification method of the landscape water body apparent pollution according to the characteristic indexes and the ranges of thresholds of the indexes; and finally, repeatedly selecting different sampling points to collect the data so as to perform coincidence ratio verification and threshold correction on building of the apparent pollution classification method until the coincidence ratio is up to 90 percent or above; primarily completing the building of the apparent pollution classification method; and dividing apparent pollution of the landscape water body into an organic dominant type, an inorganic dominant type, a nutritional dominant type and a mixed type.

Description

technical field [0001] The invention relates to the technical field of landscape water body classification, in particular to a method for establishing a landscape water body apparent pollution classification model and a landscape water body apparent pollution classification method. Background technique [0002] Apparent pollution of urban landscape water body refers to the phenomenon that due to the influence of human activities, after pollutants enter the water body, under the influence of various external factors, the water body will appear turbid, different color, smell and other phenomena that cause human sensory discomfort. [0003] With the development of the city, the functions of drinking water and waterways of urban water gradually disappear, and the landscape function becomes its basic function. Pollution has seriously affected the image of the city and affected the happiness and joy of urban residents' life. Therefore, the National Water Ten Articles have made cle...

Problems solved by technology

[0003] With the development of the city, the functions of drinking water and waterways of urban water gradually disappear, and the landscape function becomes its basic function. Pollution has seriously affected the image of the city and affected the happiness and joy of urban residents' life. Therefore, the National Water Ten Articles have made clear requirements for the restoration of the basic landscape functions of urban landscape water bodies.

[0004] At present, in view of the apparent pollution of urban landscape water bodies, the existing technology cannot analyze the causes of the apparent pollution of urban landscape water bodies, cannot clarify the direct cause of the apparent pollution of urban landscape water bodies, and cannot provide preventive strategies for the apparent pollution of urban landscape water bodies. Provide scientific theoretical basis and suggestions for the formulation of restoration plans
