洞庭湖区澧阳平原有全国最密集、文化序列最清楚的史前遗址,是研究人与自然关系演变过程的重要地区。该区的文化层不仅蕴含了考古文物资料,而且赋存了大量的古代自然与人文环境的信息,其地球化学记录为解读人地关系提供了一把钥匙。通过对21处遗址114件不同时代的文化层及其生土层、表土层样品的地球化学特征的研究,认为文化层的常量元素更多地反映了自然环境的状况,新石器中期以后的文化层的微量元素则反映了人类活动的特征。不同时期文化层的元素组合反映了不同自然与文化阶段的古代自然和人文环境的特征,据其地球化学综合指标的分类可获得关于文化和环境演化统一性和阶段性的本质认识。
The Pingyang Plain in Dongting Lake contains the most prehistoric sites in China with the most dense and well-documented cultural sequences, and is an important area for studying the evolution of the relationship between man and nature. The cultural layer of the area contains not only information on archeological artifacts, but also contains a large amount of information on ancient natural and human environments. Its geochemical records provide the key to interpreting the human-land relationship. Through the study of the geochemical characteristics of 114 cultural layers of different ages in 21 sites and the samples of raw soil and topsoil, it is considered that the constant elements of the cultural layer more reflect the status of the natural environment, the culture after the Neolithic period Layer trace elements reflect the characteristics of human activities. The elements of the cultural layers in different periods reflect the characteristics of the ancient natural and human environments in different natural and cultural stages. According to the classification of comprehensive geochemical indicators, the essence of the unity and stage of cultural and environmental evolution can be obtained.
