| 摘 要： | 水体沼泽化与陆地沼泽化这2种基本类型，已为众多学者公认，但它们的组合类型即水一陆转换式沼泽化类型，尚未引起学术界足够的重视。导致某泥炭层形成过程中泥炭沼泽化类型及其转换的直接原因是水文条件，特别是覆水深浅的变化与稳定程度，而引起后者变化的主导因素是地质构造、气候或二者的综合。马来西亚沙捞越巴兰河三角洲泥炭地和广东湛江遂溪下某泥炭地是第3种泥炭沼泽化（水-陆转换式）类型的现代实例。根据对泥炭沼泽化作用控制因素和国内外古今泥炭沼泽演化类型实例分析，归纳了3种聚炭水文模式。 |
| 关 键 词： | 陆地沼泽水 水位沼泽化 水-陆转换式沼泽化 水文条件 聚炭模式 |

PEAT-SWAMPING PROCESSES, CONTROLS AND THEIR HYDROLOGICAL MODELS FOR PEAT ACCUMULATION |
|
| Abstract: | Based on our investigation of medern peatlands in the world, the evoution of peatfondng theres can be generalized as three distinct tpo, i. e., water-swarnping process, landswamping pme, and the alternating type of the both. The first two are fundamntal types,representing a peat mire evolved from either an open water setting or an exped land setting,whereas the third one represents a compound twe, consisting of a multiple evolution of a peatmire which includes several repeated land-swamping and water-swamping stages. The rnaor direct control on their evolution may be the fluctuation of surfac-water level or ground-watertable of the peatlands, as a response to the changes of climate and tectonic movernents, or thecomination of both- Three hydrological mthels for the evolution of peat mires and the accurnulation of peat deopits have been prope here, in order to reconstruct peat-formng processesand to prospect geomtry and quality of ed deopits. forral examples of the medern peat andthe ancient ed sequences have ben described and interpreted in term of peat mire-formringprocesses and their hydrological models. |
