人类的产生和发展与自然环境有着密切的关系。对于原始人类生态环境的了解,主要依赖于对当时自然环境的深入研究。不久前发现的陕西蓝田锡水洞遗址,虽然还未找到人类的化石,但其丰富的文化遗物和遗址,都证明它确实是旧石器时代古人类居住生活过的地方~①。锡水洞遗址文化层层系清楚,物质组成复杂,包括人类用火遗留的灰烬层,地下水沉积的泉华层、洞顶坍塌角砾和来自洞外的粉砂土层等,总厚度约8米,这些不同成因的堆积物中,都
The emergence and development of human beings are closely related to the natural environment. Understanding of the original human ecological environment mainly depends on the in-depth study of the natural environment at that time. The discovery of the Xiushui Cave Site in Lantian, Shaanxi Province, not long ago, has not yet found human fossils. However, its rich cultural relics and sites have proved that it is indeed the place where ancient Paleolithic peoples lived and lived. The cultural layers of the Xiushui Cave site are well-defined and have a complicated material composition including an ash layer left behind by human beings, a Quanhua layer deposited by groundwater, a brecciated roof collapse and silt layers from the outside of a cave, with a total thickness of about 8 Rice, these different causes of the accumulation, all
