| 摘要: |
| 通过对云南滇池泥炭的考察和分析，阐述了滇池泥炭的基本特性和赋存特征。进而讨论了滇池泥炭形成的古地理环境，它不仅在成炭理论上具有意义，而且对普查和勘探泥炭资源方面也有一定的参考价值。滇池为我国西南地区最大的淡水湖泊，位于云南高原的中部，昆明市西南郊，海拔1890m。滇池也是昆明断陷盆地的沉降中心。盆地的全新统及现代沉积中有泥炭聚积，其下部更新统地层中则有褐煤赋存。因此，对全新世以来泥炭沼泽及其形成的古地理环境的研究，不仅可从一个侧面了解滇池现代演变过程以及成炭机理，而且为云南高原其它类似地区寻找和勘探泥炭资源亦有实际意义。 |

| Abstract: |
| Dianchi Lake is abundant in high quality peat in Yunnan Province. It is distributed along the littoral areas in the northern and southern parts of the lake And mainly deposited in the long-linear deltas of the longitudinal rivers except for some exposed peat which spreads over the northern bank of Dianchi lake, Chaohei and Haigen. Dianchi Lake has thicker layer peat in its northern bank than in the southern bank with the reserves dccrcaseing eastwards. The quaiernary strata contain successive lignite or peat deposits. The peat in Dianchi Lake was formed under the same climate as the present in Holocene by the factors of geology, geomorphy and hydrology. |
