| 摘 要： | 湖泊沉积物中磷的含量及形态分布等地球化学信息可以用来反演湖泊流域的古环境及污染历史。本文以乌梁素海和岱海两个不同类型的湖泊为研究对象，对两个湖泊沉积柱芯中磷形态分布的差异性进行了研究。结果表明，乌梁素海和岱海沉积柱芯中沉积磷的主导形态均为ACa P、De P和 Or P，但乌梁素海表层沉积物和沉积柱芯中Al P和 ACa P的含量水平明显高于岱海，而Ex P、De P和 Or P的含量水平明显低于岱海。两个湖泊沉积磷形态分布的差异性能较好地揭示出湖泊流域的地理环境、化学风化程度以及湖泊富营养化类型的差异性，沉积柱芯中ACa P含量及其分布特征能很好的指示湖泊自身发展过程中的富营养化水平，而De P含量及其分布特征则能较好的揭示出整个湖泊流域的古环境古气候信息。

| Abstract: | The sediments hold information of,for example,phosphorus,which can be used to reconstruct the paleoecological and pollution history of the lakes and their drainage basins.In this paper,phosphorus forms in sediment cores from the Wuliangsuhai Lake and the Daihai Lake were extracted by a sequential extraction technique.The results indicate that the contents of Al-P and ACa-P in the Wuliangsuhai Lake are notably higher than those in the Daihai Lake.However,the contents of Ex-P,De-P and Or-P in the Wuliangsuhai Lake are obviously lower than those in the Daihai Lake.The distribution of phosphorus forms can archive the information of eutrophication level and the palaeoenvironment and paleoclimate of the drainage basin of the two lakes located in different climatic regions.The contents of authigenic apatite,CaCO3-bound P,and biogenic apatite(ACa-P) and detrital apatite(De-P) can be used as effective parameters in the study of palaeoenvironment and paleoclimate. |
