Abstract

Abstract

The contents of N,P,heavy metal in the Jiaozhou Bay coast of Licun River and Haibo Riverestuaries sediment were measured using Shilaoren as control.Statistical analysis of contamination status and biodiversity of Deuteromycetes in these habitats were conducted.The results show that the heavy metal indexes of Licun River and Haibo River estuaries were 3.64 and 1.75,23.59 times and 10.58 times compared with control respectively.As for total N,P,the Licun Estuary was 1.73 and 1.33 higher than control and the Haibo Estuaries was 1.44 and 1.98 higher than control.Licun Estuary was more seriously polluted.The amount of culturable Deuteromy cetes decreased as the increase of pollution degree and this relevance was more relied on heavy metal index.Within a certain range,the biodiversity index of Deuteromy cetes increased as the increase of heavy metal index,however,it decreased rapidly when heavy metal in dexachieved certain value.The change of total N,Pcould only exert effect on some Deuteromy cetes populations and had little effect on the amount and biodiversity of the integrity Deuteromycetes.
