今天的甘肃,在太古时代,本是一片荒原,后被流水冲蚀,年代久远,渐成纵横交错的河谷。河谷两侧,黄土堆成台地,避风防水,宜住宜耕,甘肃的远古居民,就居住在这些台地上。老古学家报告,早在一二十万年以前,甘肃大地上就有古人类活动。他们劳动的工具,多半用石头、骨头或木头做成。考古学家根据古人类生产工具的制作特点,把原始社会划分为旧石器时代和新石器时代两个阶段。旧石器时代人类使用的一些石制工具,已经在华池、镇原、庆阳、环县、泾川和西部的酒泉一带发现了,与之共存的,还有动物化石等。这是研究甘肃古人类生产、生活状况宝贵的实物资料。
Gansu today, in the Pacific era, this is a wasteland, after the water washed away, old age, gradually became criss-crossed valley. On both sides of the valley, loess heap into a platform, sheltered from water and wind, should live in Yichang, Gansu’s ancient inhabitants lived on these platforms. Old archeologists reported that there were ancient human activities on the earth in Gansu one or two hundred thousand years ago. The tools of their labor are mostly made of stone, bone or wood.
