Abstract

The invention provides a method for identifying suspected pollution discharge of a sea inlet based on a high-resolution satellite image. According to the method provided by the invention, the suspected pollution discharge identification model of the seaborne discharge port is established based on the spectral characteristics of the high-resolution satellite image, the suspected pollution discharge port can be quickly screened, the water color condition of the seaborne discharge port along the bank can be dynamically and comprehensively monitored, the pollution generation and evolution process can be quickly mastered in detail, the seaborne discharge port can be supervised and managed from the aspect, and the seaborne discharge port pollution discharge identification efficiency can be improved. Resources such as manpower and material resources are saved, terrestrial pollutants are strictly supervised to enter the sea, and the ecological environment quality of offshore areas is improved.

Description

technical field [0001] The invention belongs to the technical field of marine environmental protection, and in particular relates to a method for identifying suspected sewage discharge from a sea discharge outlet based on high-resolution satellite images. Background technique [0002] The sea discharge port refers to the port that directly discharges the inland water body to the coastal waters through sluices, pipelines, ditches, etc., showing the characteristics of small area and wide distribution. The special geographical location makes it subject to multiple influences such as land-based pollution, river input, sediment resuspension, adjacency effect, etc. The nature of water bodies and pollution sources are complex, which is an important node for ecological environment governance. The direct discharge of terrestrial pollutants into the sea through the sea discharge outlet will affect the quality of the ecological environment in the coastal waters, which is reflected in a...
