新疆博斯腾湖的湖滨沼泽

LAKESHORE SWAMPS OF BOSITENG LAKE IN THE XINJIANG AUTONOMOUS REGION

新疆博斯腾湖的湖滨沼泽是我国干旱区面积最大的沼泽地。稳定的水源补给是沼泽形成的主要因素,凹陷盆地为沼泽形成和泥炭堆积提供了良好的空间场所。本区沼泽来源于水体沼泽化,沼泽类型比较单一,蕴藏着丰富的芦苇和泥炭资源。博斯腾湖及其沼泽在维持区域生态平衡中具有重要的作用。

Covering an area of about 400 km2, lake-shore swamps of Bositeng Lake in Xinjiang is the largest .areal swamp land in the arid zone of China. This area is of the to temperate desert climate. Kaidu River with an origin in Tianshan Mountain and other creeks discharge a total of 41.6×108m3 water annually into the Yanqi basin. This stable water supply is the leading factor for swamp formation. Yanqi basin is a good place for swamp formation and peat accumulation. .Swamps in this area are formed by the paludification of waferbody. The swamp is mainly of the eutrophic herb reed and eutrophic herb Typha type in the luxuriantly developing-stage. Swamp is rich in reed and peat resources. The annual production of good quality reed can reach 22.95 ×104t, an abundant raw material resource for papermaking industry. Peat reserves in swamps are nearly 10s t. But peat in this area is unsuitable for large scale exploitation.Bositeng Lake and the lakeshore swamps are the special ecosystem under desert climate conditions, which plays an important role in maintaining regional ecological balance.
