河鲀网箱养殖区大型底栖生物对氮、磷营养盐通量变化的响应
Response of Macrobenthos in the Balloonfish Net-cage Mariculture Area to Nitrogen, Posphor Nutrient Flux Change
摘要
Abstract
[Objective] The study aimed to research the two relations between the biological changes of benthos and the nitrogen, posphor nutrient flux change in the marine sediment and water interface. [Method] The macrobenthos of seafloor sediment was sampled and analyzed in the balloonfish net-cage mariculture area in Xiangshan harbor for 3 times in Jan., May and Jul. of 2008. The diffusion flux of nitrogen, phosphor nutrient in marine sediment and water interface was estimated by using Fick first law. [Result] The total biological abundance in the non cultured area was 666.0 ind/m2 , which was more than cultured area (151.8 ind/m2). The change of nitrate diffusion flux had indicative function on the total change of water nutrition. The nitrate data and benthos variety index had significant relation and the correlation coefficient was 0.762. In the 1,5 month of slack season, the nitrate data and benthos variety index, evenness index had significantly negative relation and the correlation coefficient were -0.714 and -0.857 resp. [Conclusion] This research established the response mechanism of benthos to nitrogen, posphor nutrient flux change.关键词
