摘要:
根据1990年8月至1993年10月,对太湖进行的14次调查442个表层沉积物中OM、TN、TP进行分析,其结果表明,三者均有明显的平面分布特点。近年来OM和TN增加速度较快,TP相对较慢。引用有机指数和有机氮评价太湖表层沉积物,仍处于较清洁至尚清洁状态。但东太湖底泥已遭受较严重的有机物污染。

Statement and evaluation of organic matter, total nitrogen and total phosphate in surface layer sediments in Taihu Lake
Sui Guirong
Abstract:
During three years from Aug.1990 to Oct.1993, 14-time investigation were carried out to take 442 samples of organic matter, total nitrogen and total phosphate in the surface layer sediments.The analytical results show that they are characterized by plane distribution.In recent years, the organic matter and total nitrogen increased rapidly, but by no means of total phosphate.By evaluating the surface layer sediments with organic index and organic nitrogen it is showed that the lake is in the state of clear and less clear except East Taihu Lake which has been contaminated heavily by organic matter.
Key words:  Taihu Lake  surface layer sediment  organic index  organic nitrogen e-vaiuate
