15px;">杨家坝遗址发现的遗迹多为灰坑、灰沟及柱洞,遗迹类型较为单一,其中较为特殊的是大面积红烧土硬面的发现,对于判断遗址性质具有较为重要作用。结合周边考古发现可知,在遗址溯乌江而上约<span style="font-family: Calibri;">2</span>公里的盐井峡发现有盐业遗址,发现了盐井、人工平台、盐灶、摩崖石刻等遗迹,确认这是一处明清时期的制盐遗址。根据相关文献记载,发掘者推测盐井峡盐业遗址可能是宋代白马盐场下辖的武龙咸泉所在地。杨家坝遗址发现较为特殊的红烧土硬面遗迹和较为单纯的宋元遗存,且遗址地处盐井峡下游的出峡口,地理位置关键,或许可能与当时的盐井峡盐业遗址及白马盐场有一定联系。另据当地老盐工介绍,民国时期曾有专人将盐井峡遗址流出的盐水用船顺乌江而下装运至杨家坝及对岸的杨家湾进行贩卖,说明了杨家坝与盐井峡在时代更晚的民国时期仍有紧密联系。<o:p></o:p></span></p><p style="line-height: 2em;text-indent: 2em;"><span style="font-size: 15px;"><span style="font-family: 宋体;">杨家坝遗址南面为乌江的石床滩,明代万历《重庆府志》记载石床滩有龙泉盐井,</span><span style="font-family: 楷体;">“</span><span

style="font-family: 宋体;">综上所述,杨家坝遗址很可能与宋代白马盐场有一定联系,在南宋及明清两个时期与制盐产业关系密切,因此我们推测本次发掘的大面积红烧土硬面很可能就是制盐活动的遗留。然而,受限于铁路保护范围目前揭露面积有限,对该遗迹及遗址的性质判断还有待今后做进一步的发掘和科技检测工作。</span></span></p> 前两年已经把宝挖走一次了 继续
