Construction method of quick forecasting operation system of fishery fishing condition

Abstract

The invention relates to a construction method of the quick forecasting operation system of fishery fishing condition. The construction method comprises the following steps: adopting a satellite remote sensing system, a geographic information system and a fishery environment feature library to establish a multi-granularity fishery industry fishing condition analysis database; adopting a generalized additive model to carry out quantitative analysis on relationship between the fishery and a plurality of environment factors and fishing factors, definitizing the center fishery space-time change rule and the influence factors thereof of a long time sequence, and mastering the center fishery space-time change rule and a formation mechanism; and according to the fishery space-time change rule and the formation mechanism, constructing a fishery forecasting model based on a key marine environment factor driving mechanism, establishing various fishery forecasting models to realize the comprehensive forecast of a fishery, and proposing a fishery forecasting accuracy improvement scheme. Since a control is used for carrying out visual representation to main environment factors, a series of standard business-oriented flows is constructed to determine the analysis, the charting and the quick release of a fishery fishing condition forecast map, and reference and guide are provided for fishery quest for direct scene fishery industry production.

Description

technical field [0001] The invention relates to the technical field of fishery situation forecasting and system operation, in particular to a construction method for a fishery situation fast forecasting operation system of a fishery. Background technique [0002] Chilean jack mackerel (Trachurus murphyi) is one of the more important marine economic fishes in the world. It is an oceanic, pelagic and highly migratory fish. The Chilean jack mackerel catch in the Southeast Pacific has been among the top in the world for many years. From 1978 to 2005, its total output was more than 1 million tons, and it was widely distributed throughout the South Pacific Ocean, in the exclusive economic zones of countries such as Ecuador, Peru, Chile, and New Zealand, and in adjacent high seas. my country's Chilean jack mackerel fishery was developed relatively late (started in 2000), but it has developed rapidly and has become an important fishing country for Chilean jack mackerel in the high ...

Problems solved by technology

[0003] Facing the urgent requirements for the development of my country's Chilean jack mackerel fishery, problems such as unknown fishery environment and sea conditions, lack of fishery information services and rapid forecast products have long plagued the development of my country's large-scale trawl fishery, especially Chile, which has not yet achieved commercial operation in China.
