英文摘要：

Terrestrial mollusk fossils from Chinese loess strata have been studied over one hundred years. However, the greatest progress has been made only in recent two decades. In this paper, we review the advances in land snail from the Chinese loess deposits and their paleoenvironmental implications. The improvement of research methods and approaches permits us to get more paleoenvironmental and palaeoclimatic information from mollusk assemblages. The broadened research scope and content lead to many new findings and results. Thus, mollusk record becomes one of the most important proxies in paleoenvironmental and paleoclimatic reconstruction of loesspaleosol sequence in China. The main progresses in land snail study of Chinese loess sequence are summarized as follows： 1 ） Modern mollusk assemblages are divided into four ecotypes based on their requirements of temperature and humidity, including eurytopic, semi-arid and-wet, cold-dry adapting, and warm-humid prefering types; 2） Quaternary mollusk assemblages are modified into the following three ecological types： glacial loess, interglacial paleosol,and interstadial weakly-developed paleosol assemblages; 3）Mollusk records successfully reveal long-term climatic and environmental changes and the history of East Asian monsoon variations since Late Cenozoic. Moreover,the succession of mollusk species indicates short-term environmental changes such as millennia climate variability during Last Glacial Maximum and instable climate fluctuation in glacial and interglacial periods like MIS 11 and last glacial periods.
