specific Embodiment approach 1
[0077] This embodiment is a water area shoreline pollution risk assessment method, including the following steps:
[0079] 1.1. Make three sample data sets of water coastline remote sensing images, aerial images and real images, and cut the water coastline remote sensing images, aerial images and real images into RGB three-channel images with a fixed size of 256*256*3. The absolute resolution is 0.13m / pixel, and artificially mark the constituent elements such as woodland, farmland, water body, buildings, and shoreline of the water coastline;
[0080] 1.2. Construct a fusion convolutional neural network based on InceptionV3 and attention mechanism for water coastline remote sensing images, aerial images and real images;
[0081] 1.3. For the shoreline remote sensing image, aerial image and real image of the water area, respectively set the type of model recognition, optimization target, number of iterations, use high-...
specific Embodiment approach 2
[0122] This embodiment is a water area shoreline pollution risk assessment method, according to the comprehensive index of water area shoreline pollution risk is I n The process of achieving a pollution risk assessment of the shoreline of a water body includes the following steps:
[0123] Water area shoreline pollution risk comprehensive index I n The value range is 0 to 4, and the score of the waters shoreline pollution risk comprehensive index is graded, when 0≤I n <2, the risk level of the section is low risk;
[0125] If 3≤I n <4, the coastline risk level of the section waters is high risk.
[0126] Other steps are the same as in the first embodiment.
specific Embodiment approach 3
[0128] This implementation mode is a water area shoreline pollution risk assessment system, and the system described in this implementation mode is used to implement the water area coastline pollution risk assessment method described in the first or second specific implementation mode.

technical field [0001] The invention relates to a water area shoreline pollution risk assessment method and a control intelligent decision-making method. It belongs to the intersection field of environmental engineering technology and computer technology. Background technique [0002] The shoreline of the water area is the general designation of the belt-shaped area within a certain range of the river and lake waters on the water and land boundary. Ecosystem service functions such as habitat and climate regulation play an important role in the development of urban economy and the construction of ecological civilization. However, with the development of my country's economy, problems such as illegal sewagedischarge, barrier building, fishing, breeding, sand mining, mining, reclamation, etc. encroaching on the shoreline of water areas are becoming more and more serious, which in turn leads to the deterioration of the water environment quality of rivers and lakes, and there a...
