Abstract:

摘要: 在北部湾防城港沿岸采集土壤样品,通过测量样品137Cs比活度及有机质含量,确定了137Cs背景值,分析表层土壤中137Cs分布特征,并探讨样品中137Cs活度与有机质含量的关系。结果表明:研究区土壤中137Cs背景值为626±15 Bq/m2,自然因素和人为活动对137Cs在海岸带表层土壤中的再分配起到重要作用,不同表层样中137Cs比活度高低表现为:自然林地>水稻田>旱田>草地>河口海湾。把研究区土壤表层样及P01剖面样中137Cs含量与有机质含量进行相关性分析,结果表明:两者相关性显著,相关系数分别为0.414和0.732。通过探讨研究区137Cs背景值及沿岸表层土壤137Cs分布特征,可为进一步定量研究北部湾沿岸土壤侵蚀和堆积状况以及评价防城港红沙核电站运行后对环境的影响提供科学依据。
