摘要: |
黄旗海是一封闭湖泊, 气候是控制其湖面变化的主要因素。地貌、沉积物、地球化学分析及历史考古资料均证实, 一万年以来湖面在总体收缩下降过程巾不断地波动着。全新世初期, 湖面扩张抬升, 9000a B.P.前后湖面达最高(1340m), 湖面面积也最大(约560km~2), 其后, 湖面持续地收缩下降。 |

Abstract: |
Huangqihai Lake is an inland closed lake. Climatic change is a major factor to control the lake level fluctuatiunc. The analysis on geomorphology, lacustrine sedimentolugy, geuchemistry and historical archecnugy proves that the lake level has been fluctuating since 10000 a B. P. During the early Holocene, the lake level began rising and reached its maximum height at y000a B. P. ur a maximum area of the lake. Then the lake level began to fall and its surface area to be reduced successively. |
Key words: Holucene lake level fluctuation Huangqihai Lake |
