鄂尔多斯盆地旧石器时代的地理环境变迁

Paleoenvironment variation of the paloithic age in Erdos Basin

通过对鄂尔多斯地区旧石器地点的分布状况进行梳理研究,并根据黄土地层,分区探索了鄂尔多斯盆地在旧石器时代北部毛乌素沙漠地带、中部黄土丘陵地带、南部黄土高原残原地带的地理环境变化。认为鄂尔多斯盆地以及黄土高原中腹地带在旧石器时代经历了冰期和间冰期的多次气候旋回和次一级的气候波动,环境经历了沙漠的南侵和退缩、消失和复活,草原和森林的交替,动物群的南迁和北移。

We studied the distribution and location of the paleoithic ages in Erdos Basin,and its distribution characteristics and status in China were analyzed.According to the loess research we have established the stratigraphic sequence of Erdos Basin,investigated the climate change and the geographical environments in the northern Muus Desert area,hilly county of central Loess Plateau area,wouthern Loess Plateau area of Erdos Basin.We concluded that the climate here experienced the glacial epoch and interglacial period climate cycle and a sub-first grade climate fluctuation,the environment experienced the desert expansion to south and shrink back,disappear and emergence;The alternation of grassland and forest,animals shifted between the south and north.Meanwhile,archaeology should absorb the research results of the loess,ice core,ancient terrestrial magnetism and geologic strata as far as possible to do the geologic analysis.
