| 中文摘要:在湖泊环境研究中，淤泥质沉积物取样是一项很重要的工作，样品的取心率和原状性直接影响了环境研究的结果。重力取样器是获取湖泊、水库等水域浅层湖泊沉积物的一种经济有效、操作简单的常用工具。因此研究重力取样器的取样技术对环境研究具有积极的意义。研究了重力取样器的取样技术，并在此基础上成功设计了一种便携式的重力式取样器，非常适合环境研究机构的沉积物取样工作。 |

| Abstract:Sampling undisturbed lacustrine sediment is a critical job for environmental research. The recovery and undisturbedness of samples have direct effect on the environmental research results. Gravity corer is an efficient, cost-effective and easy-to-operate tool to sample shallow lacustrine sediment in lakes and reservoirs etc. water areas. Thus, it will improve the environmental research to study the sampling technology of gravity corer. This paper explains the specific sampling technology of gravity corer. On the basis of such research, it also presents a portable gravity corer, which is regarded as a suitable sediment sampling tool for environmental research sectors. |
