| 摘 要： | 对慈溪市饮用水源地上林湖水质和底泥污染调查研究表明,上林湖饮用水水源地的水质已从2级安全水平降到了3级基本安全水平.上林湖沉积物中总磷的含量约302mg/kg,其中有机磷占31.6%,无机磷占68.4%;沉积物中活性磷含量较高,主要以Fe-P为主,在外力扰动条件下易于向水体释放影响水质.湖区周边杨梅林地施肥土壤中速效磷...

| Abstract: | Based on the survey of status of drinking water source in Cixi County,assessment of water quality of Shanglin Lake is carried out.The water quality level falls to grade 3(safety basically) from grade 2(safety).Total P concentration in sediment is 302mg/kg,in which organic P accounts for 31.6% of the total P,and inorganic P accounts for 68.4%.Sediment contains much active phosphorus,P bound as Fe(Fe-P) was the dominant bioavailable phosphorus.The release characteristics of phosphorus were influenced markedly... |
