Actual measurement method of ecological regulation and control range of artificial fish reef area

Abstract

The invention provides an actual measurement method of an ecological regulation and control range of an artificial fish reef area. The actual measurement method is used for representing flow field regulation and control and material conveying ranges of the artificial fish reef area in a marine ranching by using the water temperature difference phenomenon at a seasonal thermocline layer, namely a surface and bottom layer, existing in offshore sea areas of the subtropics from last spring to early autumn and through synchronously observing the vertical difference value of water temperature through a plurality of temperature chains. According to the actual measurement method, more than 9 stations carry out synchronous observation, wherein the synchronous observation time at every turn is more than 12.5h, observation is carried out during the grand tide, the moderate tide and the neap tide once respectively, and the regulation and control range of the artificial fish reef area is completely estimated. Approximately considered by the actual measurement method, the core putting area of the whole artificial fish reef cluster is a regulation and control range core area; stations are uniformly deployed in a marine area range regulated and controlled by the artificial fish reef area, the stations in which the temperature difference of the surface bottom layer is remarkably reduced is in a fish reef cluster regulation and control range, all stations in which the temperature different is remarkably reduced under the same tide condition are wired, and the area of closed region at the most peripheral wiring area is the artificial fish reel area regulation and control range under the tide condition.

Description

technical field [0001] The invention relates to the technical field of marine engineering measurement and calculation, in particular to an actual measurement method for the ecological control range of an artificial reef area. Background technique [0002] Artificial reefs are artificial structures placed in the ocean to improve the ecological environment of sea areas and increase fishery resources. They can be divided into sunken artificial reefs and floating artificial reefs. In the 21st century, artificial reef projects of different scales are being built in various coastal areas of my country, mainly of the submerged type. After the artificial reef is placed on the seabed, it will generate an upwelling flow on the upstream side and a back vortex on the backflow side due to the action of the tidal current. Upwelling can continuously transport nutrients from the bottom of the ocean to the euphotic layer, thereby increasing the primary productivity of the sea area, and then...
