Description

Water ecology evaluation method and system based on deep learning algorithm
Technical Field
The application relates to the field of data processing, in particular to a water ecology evaluation method and system based on a deep learning algorithm.
Background
In the prior art, elements for evaluating the quality of the water ecological environment of a river mainly comprise physical and chemical parameters of a water body, physical habitat and biological groups. The water physical and chemical parameters and physical habitat can be scored by unified relevant standards or the same scoring system established by an environmental supervision organization, so that no deviation problem exists in calculating the final score. There are different index systems for biota groups, including BMWP scoring system, chandler biological index, shannon-Winner diversity index, hilsenhoff index, palmer algae pollution index, and biological integrity index. Different index systems are different for biological species, and the emphasis of index calculation is different, so that different index systems are selected for calculation for different watercourses. When the aquatic organism index is calculated, an index system adapting to the characteristic is selected according to the characteristics of the river basin, or the index system suitable for the river basin is selected purely according to the advice of a river basin environment responsible department or the experience of an environmental protection expert, and the index system with a higher score is promoted to be selected in the condition, so that unified, objective and reasonable evaluation and ranking of all the river basins in the whole country cannot be realized. Aquatic organisms in a body of water include phytoplankton, zooplankton, benthonic animals, fish and large aquatic weeds, but the above-mentioned index system does not perform comprehensive calculation on all aquatic organisms, for example, a BMWP integral system and a Chandler biological index are only suitable for evaluating large benthonic animals, but the types of data are different, the former is used for scoring and evaluating qualitative monitoring data, and the latter is used for quantitatively monitoring data. While Palmer evaluates the results of qualitative monitoring of algae. It is contemplated that the same scoring style will also tend to be different for several basins that select the same scoring style. And for the water body in the flow domain, the scoring mode also causes the phenomenon of unfair evaluation.
Therefore, how to provide a unified, reasonable and objective evaluation method for the quality of the water ecological environment in all the watercourses is an urgent problem to be solved in the field.
