| 摘 要： | 测试研究了胶州湾近岸李村河、海泊河入海口沉积物中氮、磷及重金属含量,以石老人近岸沉积物作为对照,对其污染状况与该生境半知菌种群数量及多样性进行了统计分析.结果表明:李村河与海泊河入海口重金属综合污染指数分别为3.64和1.75,分别为对照区的23.59倍和10.58倍;李村河入海口总氮、总磷平均值分别为对照区的1.73倍和1.33倍;海泊河入海口总氮、总磷平均值分别为对照区的1.44倍和1.98倍;李村河入海口综合污染最为严重.沉积物中可培养半知菌数量随着污染程度(污染指数)增加而减少,这种变化与重金属污染的相关性较强,在一定的变化范围内,重金属综合污染指数增大时,半知菌多样性指数也相应增大,但达到一定程度时,半知菌多样性指数会迅速下降接近为0.氮磷的变化只对半知菌部分种群的数量产生影响,对半知菌整体的数量以及多样性的影响不明显.

| 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. |
