本文通过分析区域新构造运动形势,明确浙江余杭良渚遗址群属于断块下沉的古海湾区,区域地貌和第四纪沉积物的特征受新构造运动差异性的影响。作者从新构造运动观点论述考古遗址群的环境变迁,由于地壳的持续下沉,加剧海侵的危害,更多内涝形成,洪水向下游不易渲泄,以及大面积的地下水位上升,影响农作物的生长,人类居住环境恶化,从而导致了良渚文化的衰落。
In this paper, by analyzing the tectonic movement in the region, it is clear that the Liangzhu site in Yuhang, Zhejiang belongs to the ancient Gulf area where the fault blocks have subsided. The regional topography and the characteristics of Quaternary sediments are affected by the differences in neotectonic movement. From the viewpoint of neotectonic movement, the author discusses the environmental changes of archeological sites. Due to the continuous sinking of the crust, the danger of transgression, the increase of waterlogging, the difficulty of venting the flood to the lower reaches and the rise of large-scale groundwater table, affecting the growth of crops, The deterioration of the living environment of human beings led to the decline of Liangzhu culture.
