| Abstract: | Along with the overexploitation of marine fishery resources and increasing deterioration of environment,macrobenthos living in the intertidal zone between land and sea are facing a serious threat of stock recession.In order to restore the population resources and improve the eco-environment of the zone,the governments at different levels are exploring a model of sustainable enrichment release while increasingly to do so.Taking the intertidal zone of Zhuyaoyu islet,Dachen islands as an example,a stock enhancement protection area has been built up and background and tracking survey of the macrobenthos there were carried out.The results show that the number of species in 2007(52 species) and 2009(55 species) is higher than that in 2006(24 species),especially molluscs and macroalgae that increased most.The average population mean biomass and abundance distribution is in order of 2009(2 879.02 ± 1 120.36)g/m2,(766±435.35) ind/m2)] > 2007(2 460.83±1 356.42) g/m2,(691±330.27) ind/m2 ] > 2006 (408.64 ± 212.83) g/m2,(363±221.50) ind/m2)].And the biodiversity index and Margale’s species richness index in 2007(1.33,2.25) and 2009(2.36,5.24) are bigger than that in 2006(1.06,1.90).In addition,the community structure of the macrobenthos changed obviously.The dominant species were Ulva lactnca L.(0.246)and Tetraclita squamosa squamosa(0.238) in 2006;Trichomya hirsuta(0.512) and Thais luteostoma(0.113) in 2007,and Tetraclita squamosa squamosa(0.316),Trichomya hirsuta(0.165),Mytilus coruscus(0.071),Thais luteostoma(0.020) in 2009,from which it can be seen that Mytilus coruscus and Thais luteostoma that declined before became major dominant species again in the stock enhancement protection area.Analysis of the marcobenthic community structure by ABC curve shows that it was unstable and had been interfered in 2006,but became stable in 2007 and in 2009.The main reason for this is that the stock enhancement protection area has made a stable environment for the intertidal macrobenthos to live and grow,and with enrichment release of recession species,the stock number and the ecosystem of the intertidal macrobenthos has been restored and improved,and sustainable utilization of the bio-resources of the zone is achieved. |
