摘  要:
近年来,新疆地区第四纪环境演变研究已取得重要进展,但仍有许多问题值得进行探讨和讨论,这些问题主要表现在以下几个方面;(1)新疆地区第四纪下限年代的绘出目前仍有失完美;(2)新疆地区末次冰盛期以来高潮面的环境指向不同于我国季风影响区,其产生机制各有不同;(3)干旱区生物地层学的应用某些指标的选取;(4)干旱区特殊表生环境制约下的地化元素迁移、富集规律;(5)未来环境演变趋势探讨。这些问题的讨论对于新疆第四纪环境变迁的深入研究具有重要意义。

摘  要:
Many important advances have been achived recently on Quaternary environmental change in Xinjiang. But,some problems are still awaiting for further understandingand worth probing and discussing: (1) The studies on the lower boundary of Quaternary inXinjiang are still inper fect at present ; (2) The indications of high lake level since Last GlacialMaximum are different from that of the monsoonal area in China,and are with different causation ; (3) To apply Bio-stratigraphic studies in arid area,some indice are of more sensitiveenvironment at indication ; (4) The rule of migration and accumulation of chemical elements,which is controlled by the surface arid. geographic circumstance is of special characteristics ;(5) Discuss on future environmental changes.The problems discussed above are of great important significance for further researchingQuaternary euvironmental development in Xinjiang.
