天津海洋牧场人工鱼礁投放误差研究
Research on the Placement Error of Artificial Fish Reef in Tianjin Marine Ranching
摘要
Abstract
Reasonable artificial reef layout can provide suitable habitat,promote species diversity and ecosystem stability.However,affected by various factors,the actual location of the artificial reef may be different from the plan,resulting in the failure of the artificial reef con-struction to achieve the expected results.In this study,four indicators,including center of grav-ity error,peripheral area error,overlapping area error,and reef quantity error,were used to e-valuate the status of artificial reef placement errors in Tianjin Ocean Ranching.The results showed that the error of the peripheral area and reef quantity is-0.11 and 0.067,respectively,it meant that the accuracy of delivery layout was relatively high;the average error of center of gravity and overlapping area was 0.59 and 0.73,respectively,and the accuracy of delivery posi-tioning was relatively poor,which needed further improvement.From the perspective of actual changes,in 2018,the center of gravity error,overlapping area error,and reef quantity error of artificial reefs were significantly improved,and only the peripheral area error was slightly lar-ger,indicating that the accuracy has achieved the expected effect.This study quantified the placement error of artificial reefs in Tianjin Ocean Ranching,and the results could provide useful reference for improving the effect of artificial reef placement,provide a scientific basis for relevant policy formulation,and guide management practices for Tianjin Ocean Ranching.关键词
