摘要:

青藏高原具有全球重要性,是地球表面上很少受人类活动干扰的区域之一,在全球变化研究中被作为先兆区或预警区。青藏高原湿地多为高寒沼泽、高寒沼泽化草甸和高寒湖泊,具有生态蓄水、水源补给、气候调节等重要的生态功能,在防止全球水危机方面起着关键的作用。因此青藏高原湿地在全球变化研究中占有特殊的重要地位,已经引起国内外学者的关注。本文从湿地的类型和分布、湿地土壤、湿地植被、泥炭的形成与演化、湿地动物、古植被古气候、温室气体排放以及湿地退化几个方面对青藏高原湿地研究进行了综述,并提出了未来的重点研究领域。

Abstract:

The Qinghai-Tibet Plateau is a unique geographical region with the highest elevation located at unique latitudes in the world and shows special dynamic and thermal effects, thus responsible for a conspicuous hydrological cycle in the atmosphere within Asian monsoon areas, and an extremely sensitive region of land-air interactions in East Asia. It is also one of areas which is less disturbed by human activities on the surface of the earth, serving as a foreboding or early-warning area for global changes. Wetland, located in the transitional zones between aquatic and terrestrial ecosystems, is an important landscape and ecosystem. Wetlands in Qinghai-Tibet Plateau mainly include alpine marshes, alpine swampy meadow and alpine lakes, which play important roles in water storage, water supply, adjusting climate and abating global water shortage and so on. Therefore Wetlands in Qinghai-Tibet Plateau are very important for global climate changes. In this paper we summarized progresses in several study fields of wetlands in Qinghai-Tibet Plateau, such as classification of wetland types, wetland soils, wetland vegetation, formation and evolvement of peat, wetland creature, paleobotany and pristine climate, greenhouse gases emission and wetland degeneration etc., indicating that wetlands in Qinghai-Tibet Plateau have been paid much attention to. But studies on these fields also need to be strengthened. Finally, the study fields in the future were also put forward as follows: (1) Relationship between landscape pattern of plateau wetlands and ecological processes such as sediment processes, biogeochemical processes, eco-hydraulic processes; (2) Relationship between global climate changes and dynamic changes in wetland landscape patterns, including greenhouse effects and global carbon cycles, and relationship between pristine climate and pristine environment changes; (3) Restoration and conservation of plateau wetlands serious degenerated, including degeneration processes and forcing mechanism, ecological methods for restoration and conservation and index system of ecosystem health assessment and ecological risk assessment.
