Analysis on the suitability of the construction of a large deep-water bottom-mounted cage in the sea area of Wumang Island,Dalian City
In order to more accurately,more scientifically,and more efficiently evaluate the suitability of the construction of large-scale deep-water bottom-sitting cages,this paper investigates and studies the policy compliance,sea state suitability,and operational efficiency of the 321 hm2 sea area in the northwest of Wuanda Island,Dalian City,and evaluates the suitability of the construction of large-scale deep-water bottom-sitting cages in this sea area.The results show that area 1 is the most suitable for constructing large deep-water bottom-sitting cages,followed by areas 2,3,4 and 5.The most suitable construction area is mainly located southeast of the sea.The sea area is about 13 hm2,which meets the policy requirements.The seawater exchange condition is good,the seabed terrain is flat,the geological structure is stable,and the foundation bearing capacity condition is good.This area can fully meet the construction and operation requirements of large deep-water bottom-sitting cages and is conducive to the function of large deep-water bottom-sitting cages.In this study,a comprehensive evaluation system for the construction suitability of large deep-water bottom-sitting cages was constructed,and suitable construction areas were selected,which could provide a reference for the construction and development of large deep-water bottom-sitting cages in Wuanda Island sea area of Dalian City.
