| 摘 要： | 为了探明太湖水体中胶体磷含量,更深入认识营养盐在大型浅水湖泊中的循环过程和机理,分别从太湖的梅梁湾和贡湖湾两个不同类型的湖区采集水样,利用切向流超滤方法分离出胶体物质,对太湖水体中胶体磷含量进行了初步研究．结果表明:太湖水体春季胶体磷含量在0．017-0．029 mg／L间,其中梅梁湾藻型湖区胶体磷含量范围是0 023- 0．029 mg／L,贡湖湾草型湖区胶体磷含量在0．017-0．022 mg／L间．梅梁湾水体胶体磷占总磷比例平均为28．6%;而贡湖湾胶体磷占总磷比例平均达到39．3%．梅梁湾水体真溶解态磷含量显著高于贡湖湾水体,达贡湖湾的4倍．与澳大利亚的17个湖泊相比,太湖属胶体磷含量偏低的湖泊,但相对于海洋的研究结果,太湖胶体磷含量明显偏高． |

| Abstract: | Concentration of colloidal phosphorus in Lake Taihu, China, was determined in this paper. Lake water was sampled in April, 2005. Cross-flow filtration technique was applied to extract colloid from the water. The result shows that colloidal phosphorus concentration in Lake Taihu varied from 0. 017 to 0. 029 mg/L. In Meiliang Bay, an algae type zone, it is 0. 023 -0. 029 mg/L; while in Gonghu Bay, a grass type zone, it is 0. 017 -0. 022 mg/L. The colloidal phosphorus account for 28. 6% of total phosphorus (TP) in Meiliang Bay, and account for 39.3% of total phosphorus (TP) in Gonghu Bay, respectively. The true-dissolved phosphorus in Meiliang Bay is four times of that in Gonghu Bay. |
| Keywords: | Colloid phosphorus cross-flow ultrafiltradon Lake Taihu shallow lake |
