摘要: 湖泊形态是湖泊研究的基础,巴丹吉林沙漠湖泊受到各界广泛关注,却缺乏湖泊形态方面的研究。本文采用超声波测深仪与RTK-GPS测量系统相结合的方式,对巴丹吉林沙漠10个面积较大的湖泊进行了深度测量,得到了完整的湖泊形态数据。其中湖泊规模方面,布尔德以最大的湖泊面积与最小的湖泊最大深度区别于其余湖泊;湖泊形态方面,10个湖泊整体具有干旱区湖泊独有的浅水平底湖泊的特征。由于内生钙华与深处流动性沙漠的原因,利用湖泊周边地形估算湖泊容积的方法对于巴丹吉林沙漠湖泊并不适用。为此,利用测量数据,提出了估算巴丹吉林沙漠湖泊容积的经验公式。

Abstract: Lake morphometry is of fundamental importance for understanding the lake ecosystems, but it was previously neglected in researching the lakes in the Badain Jaran Desert. Here, a bathymetry survey of 10 large lakes in the desert was carried out using the ultra-sonic depth finder and RTK-GPS measurement system. Bathymetries was used to chart the relative hypsographic curves. Moreover, the morphometric parameters were calculated using the detailed lake depth data. In the lake size aspect, the Buerde Lake was distinguished from the remaining lakes because of its largest water area but the smallest maximum depth. However, the other 9 lakes were similar in their water areas, volumes, maximum depths and mean depths. In the lake shape aspect, the shorelines of the lakes were closed to circles expect the Buerde Lake, Yihejigede Lake, Sumujilin Lake and Yindeertu Lake. All the lakes could be considered as the shallow lakes. The method that the peripheral terrain is used to estimate the lake volumes is unsuitable for researching the lakes in the Badain Jaran Desert due to the location of the lakes and the endogenous travertine. Therefore, a mechanism-based empirical formula was presented in this study for estimating the volumes of the lakes in the Badain Jaran Desert in the future.
