River water ecological environment evaluation method

Abstract

The invention relates to a river water ecological environment evaluation method. The invention aims to provide a river water ecological environment evaluation method. According to the technical scheme, the river water ecological environment evaluation method is characterized by comprising the steps of acquiring a plurality of river hydrological panoramas shot at different times and attaching shooting time information and GPS position information of shooting positions yo the hydrological panoramas; identifying and intercepting an area containing a pollution source in the hydrological panorama,taking the area as a pollution source picture, and performing layer processing on a plurality of pollution source pictures at different time on corresponding GPS positions based on GPS position information of the pollution source picture; sequentially covering the plurality of pollution source pictures according to a time axis sequence to obtain a development trend of a pollution source graph line; and judging the hydrological pollution source grade according to the development trend of the pollution source graph line along with time. The invention is suitable for the technical field of ecological environment detection.

Description

technical field [0001] The invention relates to a river water ecological environment evaluation method. It is suitable for the technical field of ecological environment detection. Background technique [0002] With the continuous development of society, a large amount of industrial wastewater and domestic sewage have been discharged, and these sewage have finally entered lakes and rivers through various channels, causing a large number of lakes and rivers to be polluted and causing extremely serious damage to the natural environment. . A large number of pollutants nitrogen, phosphorus and various heavy metal elements are accumulated in natural water bodies, causing algae to proliferate, consuming a huge amount of dissolved oxygen, causing the death of plants and animals, further deteriorating the water quality, turning the water body black and smelly, causing severe environmental pollution. [0003] When the ecological environment needs to be treated, it is necessary to p...

A large number of pollutants nitrogen, phosphorus and various heavy metal elements are accumulated in natural water bodies, causing algae to proliferate, consuming a huge amount of dissolved oxygen, causing the death of plants and animals, further deteriorating the water quality, turning the water body black and smelly, causing severe environmental pollution

[0003] When the ecological environment needs to be treated, it is necessary to pre-evaluate the ecological environment in order to obtain an accurate treatment plan. Most of the ecological assessments are carried out by manual on-site exploration. Due to many environmental factors, it is impossible to obtain an accurate assessment report. , making it difficult to accurately apply the governance plan to the target area
