Whatever happened to the Harappan Civilisation?哈拉帕文明究竟发生了什么?

New research sheds light on the disappearance of an ancient society新研究揭示了一个古代社会的消失

A research team led by Petrie, together with Dr Ravindanath Singh of Banaras Hindu University in India, found early in their investigations that many of the archaeological sites were not where they were supposed to be, completely altering understanding of the way that this region was inhabited in the past. When they carried out a survey of how the larger area was settled in relation to sources of water, they found inaccuracies in the published geographic locations of ancient settlements ranging from several hundred metres to many kilometres. They realisedthat any attempts to use the existing data were likely to be fundamentally flawed. Over the course of several seasons of fieldwork they carried out new surveys, finding an astonishing 198 settlement sites that were previously unknown.

皮特里带领的-个研究团队与印度巴纳拉扌斯印度大学的拉文达纳·辛格博士一起,在他们早期的调查中发现,许多考古遗址并非在它们的真正位置,这完全改变了人们对此地作为遗址的看法。他们调查周边地区过去如何临水而居时,发现那些已经公布的古代定居点的地理位置存在不准确之处,与实际距离相差几百米至几千米他们意识到直接使用现有的数据很可能导致根本性的错误,经过几个季节的野外实地考察,他们开展了一项新的研究,发现了多达198个不为人知的聚居点。

Now, research published by Dr Yama Dixit and Professor David Hodell, both from Cambridge’s Department of Earth Sciences, has provided the first definitive evidence for climate change affecting the plains of north-western India, where hundreds of Harappan sites are known to have been situated. The researchers gathered shells of Melanoides tuberculata snails from the sediments of an ancient lake and used geochemical analysis as a means of tracing the climate history of the region. ‘As today, the major source of water into the lake is likely to have been the summer monsoon，’ says Dixit. ‘But we have observed that there was an abrupt change about 4,100 years ago, when the amount of evaporation from the lake exceeded the rainfall 一 indicative of a drought.’ Hodell adds: 'We estimate that the weakening of the Indian summer monsoon climate lasted about 200 years before recovering to the previous conditions, which we still see today. ，

目前,来自剑桥大学地球科学学部的亚玛·迪克西特博士和大卫·霍德尔教授联合发表的研究报告用确凿的证据表明,气候变化影响了印度西北部平原地区,那里正是数百个哈拉帕定居点的所在地。研究人员从一个古老的湖泊沉积物中采集了瘤拟黑螺蜗牛壳,用地球化学分析法追踪该地区气候的演变过程。“如今,流入湖泊的水源主要来自夏季的降雨。”迪克西特说道,“但是我们注意到大约在4100年前,情况发生了急剧的变化,当时湖泊的蒸发量超过降雨量——这预示着干旱”霍徳尔教授补充说:“我们估计印度夏季的降雨气候出现了200多年的持续减弱之后才恢复到以前的状况,我们今天仍然能看到。

It has long been thought that other great Bronze Age civilisations also declined at a similar time, with a global-scale climate event being seen as the cause. While it is possible that these local-scale processes were linked, the real archaeological interest lies in understanding the impact of these larger-scale events on different environments and different populations. ‘Considering the vast area of the Harappan Civilisation with its variable weather systems，’ explains Singh, ‘it is essential that we obtain more climate data from areas close to the two great cities at Mohenjodaro and Harappa and also from the Indian Punjab•’

长期以来,人们一直认。为其他青铜器时代的文明也在相似的时期衰落,全球气候变化被视为主要原因。尽管很可能这些局部的变化有所关联,但是考古学家真正的兴趣在于研究大范围环境变化对不同环境和人口的影响。辛格解释说:鉴于哈拉帕文明区域广阔,气候多变,我们必须从摩享约达罗和哈拉帕这两大城市附近的地区以及印度旁遮普获得
