关中地区仰韶-龙山聚落遗址分布演变的特点,龙山时期有无出现大规模人口迁出的现象,它们与当时的环境背景有无关系,还需要更多的资料来证明。文中以漆水河流域为例,利用文物普查资料,结合统计学,ARCGIS空间分析方法,研究上述问题。结果表明:从宏观上来说,漆水河流域龙山时期聚落较仰韶时期衰落,但比东部地区情况要好;遗址的迁徙变化更为频繁;漆水河流域遗址整体高程增高和呈远离河流的趋势,与这一时期频发的洪水有一定的关系。从微观上来说,漆水河流域各个支流和河段在遗址数量与规模组合、高程与距河流远近组合与整体演化并不一致。按数量与规模组合的不同可以将各支流和河段分为三组,从三组河流的变化趋势来看,确实存在一种东西向遗址演变模式的不同,但这种不同是否体现这一时期关中地区人口迁出这一现象还不能做最后的结论。按高程与距河流远近组合的不同可以将各支流和河段分为两组,似乎是洪水事件对不同地形地貌区影响不同的结果。最后,西部诸河数量与规模组合的与众不同似乎也可以在关中地区洪水事件发生时间的不同中得到解释。
The characteristics of the distribution of the Yangshao - Longshan settlement sites in the Guanzhong area, whether there were any large-scale population movements during the Longshan period, whether they have anything to do with the current environmental background, and more data are needed to prove this. Taking the Qishui River Basin as an example, this paper uses the census of cultural relics, and combines the statistical and ARCGIS spatial analysis methods to study the above problems. The results show that from the macroscopic point of view, the settlements in the Longshan period of the Qiushui River Basin decline compared with the Yangshao period, but the situation is better than that in the eastern part; the migratory changes of the sites are more frequent; the whole elevation of the Qiushui River Basin site and its trend away from rivers, And this period of frequent floods have a certain relationship. From the microscopic point of view, all the tributaries and river sections of the Qiushui River basin are combined in the number and size of sites. The combination of elevation and distance with the river is not consistent with the overall evolution. According to the different combination of quantity and scale, the tributaries and river sections can be divided into three groups. According to the change trend of the three groups of rivers, there is indeed a different mode of evolution of the EWS. However, whether this difference reflects this period The phenomenon of population migration in the Guanzhong area can not make the final conclusion. Dividing the tributaries and river sections into two groups according to the combination of elevation and distance to the river seems to be the result of different impacts of flood events on different topographic and landscape areas. Finally, the unusual combination of numbers and scales in the western rivers seems to be explained by differences in the timing of flood events in the Guanzhong area.
