| 摘 要： | 中新生代的准噶尔盆地为典型的内陆湖盆，四周为山系包围，是分析内陆湖泊水位升降的理想场所。本文参照全球海平面变化的计算方法，通过内陆湖盆沉积体系及其地貌特色的研究，建立准噶尔盆地中新生代湖水位升降曲线。中新生代的准噶尔盆地为一封闭型内陆盆地，湖水位升降主要受气候和构造因素的控制。笔者利用区域的气候和构造背景对湖水位的升降作了剖析，初步建立两种背景下的湖水位升降曲线。

| Abstract: | The Junggar Basin is a typical Meso-Cenozoic continental lake basin surrounded by the mountain systems,and thus an ideal locus for the study of the lake-level fluctuations in an inland lake. The relative changes of lake l.evel resulted in the development of depositional systems tracts and their base topography. The establishment of the curves for the MesoCenozoic lake-level changes in the Junggar Basin is based on depositional processes and geomorphological features of the lake basin, referenced to the computing methods of the global sea-level fluctuations. The Junggar Basin was an enclosed inland basin during Meso-Cenozoic time. The lake-level fluctuations were mostly controlled by the climatic and tectonic factors. In the present paper,the lake-level changes in the basin during Meso-Cenozoic tim are discussed,and the curves for the lake-level changes are also plotted in the light of the regional climates and tectonic settings. |
