青藏高原湖泊纳木错水域生态学研究现状与展望

Aquatic ecology in Lake Nam Co,Tibetan Plateau:current awareness and perspective

青藏高原湖泊群是世界上海拔最高、分布最密的湖群区。藏北地区的纳木错是世界上海拔最高的大湖，同时也是我国仅次于青海湖的第二大咸水湖。在纳木错开展全面的水域生态学研究，对青藏高原湖群区具有重要借鉴和示范意义。论文综述了关于纳木错水域生态系统的已有研究。鉴于纳木错水域生态系统的基本特征尚未得到全面认识的现状，建议纳木错生态研究应集中在生物地球化学循环与食物网营养动力学研究、流域人类活动的生态学效应研究、纳木错生态系统对气候变化的响应、纳木错与藏北湖泊的比较湖沼学研究等几个范畴。

The most crowded and highest lakes in the world are distributed on the Tibetan Plateau. Lake Nam Co in the North Tibet is the highest great lake in the world and is the second biggest salt water lake, only inferior to Lake Qinghai, in China. Integrated ecological research in this lake will have the important model and the demonstration significance to other lakes in the Tibetan Plateau. This article summarized ecology research in Lake Nam Co from the hierarchical components of the food web, including fishes, waterfowl, aquatic plant, plankton and benthic invertebrates. In view of the fact that basic characteristics of the lake ecosystem have not yet obtain the comprehensive understanding, we suggested the ecological concerns should be concentrated on biogeochemistry, foodweb dynamics, anthropogenic effects on lake system, climatic change response and comparative limnology research in this region.
