| 中文摘要 | 青藏高原腹部的长江河源区属千典型的现代冰缘环境,是世界上面积最大,海拔最高的中、低纬高原沼泽。沼泽的形成过程和类型特征与非冰缘区有明显不同,本文划分出10个主要沼泽类型,并阐述了生态结构特征。 |
| 英文摘要 | The source region of the Changjiang River is situated in the center of the Qinghai-Xizang Plateau,belonging to typical periglacial environment.It is found that the region is the largest and highest plateau mire distribution area of plateau mire in the middle and low latitude zones of the world.Mire there covers an area of 8000km~2.The highest is 5350m above sea level.The mire in the pert-glacial region has special regional law.Strong thaw-freeze action is involved in mire formation process,so mire type peculiar to periglacial region is formed. Mire in this region is divided into 10 basic types such as periglacial strath mire. The formation mechanism,type characteristics and ecological features are discus-sed.Microlandforms are charaeterized by common grass mound cover,freezeswell raise,wide development of peat mire on peat accumulation,the feed of ice-meltwater and meltwater from frozen earth horizon,simple types of animal community and plant community,and many endemic species.In this region, there is only herb mire,lacking in moss Mire and woody mire. |
