Embodiment Construction

[0039] A method for optimizing artificial fish reef layout based on biological suitability, comprising the following steps:

[0040] S1. Obtain the flow field effect data under the combined layout of various artificial reefs through numerical simulation experiments;

[0041] S2. According to the actual situation of the reef projecting area, select the key species that need to be evaluated for suitability before the construction of artificial reefs that are oriented to the local conditions, and comprehensively consider the specific conditions of dominant species, benthic habits, economic value, and local multiplication and release. Certainly;

[0042] S3. Formulate fuzzy logic rules for selected species:

[0043] S3.1. Considering the change of flow field conditions caused by artificial reef deployment and the needs of organisms for environmental factors, select flow velocity, suspended solid concentration, chlorophyll a concentration and shelter space as measurement indicator...

Abstract

The invention discloses a method for optimizing the layout of an artificial fish reef based on biological suitability. The method comprises steps of selecting a flow velocity, a suspended matter concentration and a sheltering space as measurement indexes through the full consideration of main environment factors affected by the construction of the artificial fish reef and the suitability requirements of organisms on the environment, and carrying out habitat suitability evaluation of organisms under different artificial fish reef arrangements. An artificial fish reef optimized combination layout method oriented to biological resources is provided, and theoretical method support is provided for construction of artificial fish reefs with guaranteed quality and improved efficiency.

Description

technical field [0001] The invention relates to the technical field of artificial fish reefs, in particular to a method for optimizing the layout of artificial fish reefs based on biological suitability. Background technique [0002] Artificial reefs have attracted much attention as a widely adopted resource restoration measure. Artificial reefs have good effects in improving the marine ecological environment, restoring fisheries and increasing production and farming. my country's artificial reef experiments began in the late 1970s. After more than 40 years of development, by the end of 2018, the amount of artificial reefs deployed had reached about 83.25 million square meters, covering all coastal cities in China. [0003] At present, the pre-reef construction plan mainly focuses on the selection of reef type and the site selection of artificial reefs. The invention mainly focuses on artificial reef technology and ecological effect evaluation. The patents mainly focus on t...
