| 中文摘要 | 中华文明源远流长，有众多历史遗迹。古代遗址分布与地理环境息息相关，研究遗址的环境宜居性，对探究古代文化遗址的时空演变与发展规律具有重要意义，同时能够更好地辅助考古学研究。本文选取榆林地区东北部的典型遗址，通过SOFM神经网络模型对区域内聚落等级进行划分，结合地形高程、坡度、坡向、距水系距离、植被覆盖度等因子，利用指数变异法客观确定各因子的相对重要性并构建指数模型，得出研究区新石器时代的环境宜居性分布规律。研究结果表明，研究区遗址大都分布在海拔1000m~1200m、坡度3°~9°、距水系距离为0~800m、坡向为阳坡以及植被覆盖度较好的区域，一级聚落均分布在古代环境宜居性较高的区域。与仅使用地形因子建立的指数模型相比，加入植被覆盖度和聚落等级因子的模型对不宜居的沙漠和遗址分布空白区域划分的宜居性等级低，对遗址分布密集的宜居区域划分的宜居性等级高，宜居性等级划分结果与各等级遗址密度分布的客观事实更为吻合，综合因子模型对区域宜居性等级划分更为精确。分析新石器时代人居环境宜居性对探索史前文明与人地关系有重要意义。 |
| 英文摘要 | Chinese culture features a long history with abundant historical remains. The distribution of ancient historic sites is closely related to their geographic environment. The environment livability research of the sites is of great importance to explore their spatiotemporal evolution and development patterns, which could also better assist the archaeological research. In this paper, typical sites in northeast Yulin, Shanxi Province, China were selected as the study area. These sites were first ranked into settlement levels using the Self-Organizing Feature Map (SOFM) neural network. Then the relative importance of settlement determinants including elevation, slope, aspect, distance from water and vegetation cover were quantified using the index variation method and an index model was developed to derive the distribution pattern of the sites’ environment livability in the Neolithic Age. The results show that these studied sites were located mostly in areas characterized by altitudes between 1000m -1200m, 3°-9° slope gradient, 0-800m distance from water, sunny slope aspect and dense vegetation cover. Level one settlements were mainly located in the areas with a high environment livability level. Compared to the model which considers the terrain factor only, the comprehensive model that incorporated vegetation cover and settlement level factor shows a better consistency between the livability level and density distribution of the sites in each level. In the model, the livability level is low in the desert and blank site area, while it is high in the densely distributed area. This comprehensive model could also classify the livability level more precisely. Analyzing the environmental livability in Neolithic age is critical to explore the prehistorical civilization as well as the man-land relationship. |
