上海松江区广富林遗址的环境分析

Analysis of the Environments of the Guangfulin Site in Songjiang District,Shanghai

前言广富林遗址发现于1959年,后曾试掘,发现2座良诸文化墓葬和春秋、战国时期的文化遗存①。1999年以来,上海博物馆考古研究部在广富林遗址进行有计划的勘探和发掘。该遗址按象限可分为四个区,通过发掘,可以确认n区以良诸文化墓地为主,工区以良诸文化、一类新的新石器时代晚期遗存和战国至汉代文化遗存为主③。这类新的新石器时代晚期遗存以往在环太湖地区从未发现过,经过数年的考古发掘和研究,对其内涵和性质有了初步认识。

The ancient environments of the Guangfulin site can be reconstructed and the mutual influence of environmental change and cultural development can be studied by means of grain size, pollen, organic carbon, magnetic parameter, geo-chemical and micro-paleontological analyses. The results indicate that before man＇ s activities there, the air temperature was a little lower at Guangfulin; during the Liangzhu Culture period, it was warm and humid; in the Guangfulin Culture period, the climate gradually became cool and dry and the environmental condition was adverse; and in the Warring States period to the Han Dynasty, the air temperature was relatively high. It is noteworthy that there was a distinct drop of air temperature in the Guangfulin Culture period, which should be studies in depth as to its effect on the fall of the Liangzhu culture and the cultural change taking place there about 4000 BP.
