Marine ecological anomaly risk identification method and device based on multi-source heterogeneous data

Abstract

The invention discloses a marine ecological anomaly risk identification method based on multi-source heterogeneous data. The method comprises the steps that a multi-source heterogeneous data file of atarget sea area is acquired; generating a quality control report according to the multi-source heterogeneous data file; establishing a marine information database according to the multi-source heterogeneous data meeting the data quality standard; the method comprises the steps of establishing an ocean numerical model on a cloud platform, and updating an ocean information database to obtain an updated ocean information database; obtaining a first-level marine ecological anomaly index data product according to the updated marine information database; performing weighted average on each marine ecological anomaly index data product to obtain a secondary marine ecological anomaly index data product of the target sea area; and carrying out threshold detection on the secondary marine ecology abnormal index data product, and if an abnormal index greater than a first preset threshold exists, sending early warning information. According to the marine ecological anomaly risk identification method based on the multi-source heterogeneous data, the accuracy of marine ecological anomaly risk identification can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of ecological monitoring, in particular to a method and device for identifying marine ecological anomalies based on multi-source heterogeneous data. Background technique [0002] In recent years, my country's coastal ecological disasters have occurred frequently, and the research on ecological disasters has become a hot topic in the academic circles. The concept of marine ecological disasters was originally derived from the definition of terrestrial ecological disasters, and the deterioration of coastal and offshore ecological environments caused by accidents such as red tides, sea pollution, and oil spills were all included in marine ecological disasters. In 2008 and 2012, the green tide disaster of Enteromorpha posed a serious threat to major international events such as the Qingdao Olympic Sailing Competition and the Haiyang Asian Beach Games; in July 2009, the jellyfish disaster encountered by Qingdao Po...
