| 1. | Particle - size features of chuodun paleosol and identification of its parent material 昆山绰墩古土壤粒度特征及母质判别 |
| 2. | Revelation of information on genesis of multi paleosol from quaternary loess profile 第四纪黄土剖面多元古土壤形成发育信息的揭示 |
| 3. | Magnetic susceptibility features and environmental records of the xiashu loess in zhenjiang , jiangsu province 镇江下蜀黄土古土壤序列磁化率特征与环境记录 |
| 4. | We got the age of the river terraces by the sequence of the loess and paleosol on the river terrace 通过各级阶地上的黄土古土壤序列的研究,得到各级阶地的形成年代。 |
| 5. | Clay minerals and surface chemical characteristics of soils developed under a palaeosol in lower west mountain area of beijing 北京西山古土壤母质上发育的土壤之粘粒矿物与表面化学特性 |
| 6. | The study on the loess - palaeosol sequence is characteristic and advantageous field of our country in the study of global change 而黄土和古土壤序列是我国在全球变化研究中的一个特色和优势领域。 |
| 7. | The data collected in this study indicates that the paleosol layer is thicker in the southeast region than in the northwest and thicker in the north region than in the south 通过各项指标区域横向对比发现,砂质古土壤层具有从西北向东南渐变厚变深的规律和粒度值从西北向东南由粗变细的规律。 |
| 8. | During the banpo man time or in the middle holocene , 5000 ~ 6000 bp , the climate within the modern glaciation best fitted vegetation and the intrusion of some sub - tropic trees was postulated to have taken place 古土壤代表间冰期夏季风盛行的湿热气候,植被比较繁盛;黄土代表冰期冬季风盛行的干冷气候,植被凋凌。 |
| 9. | Since the influence of clay materials here , the high calculations of magnetic susceptibility in fossil soil do not represent the climate elements of this layer , but represent the most warm and humid climate elements - of the upper layer 由于该区黏土物质迁移等影响,古土壤磁化率高值段一般不能代表该层段的气候要素,而是表征上层段最温湿阶段的气候要素。 |
| 10. | Others that related the ancient times climatic change , for instance ancient - river hydrodynamic force condition and so on , also are the important contents that we understand the ancient times environmental variation rule 其他与古代气候变化相关的变化,比如古土壤中稀土元素和微量元素的含量,古河流的水动力状况等,也都是我们了解古代环境变化规律的重要内容。 |
