我国海洋滩涂主要污染物的研究概况

随着经济的发展和生活水平的提高,海洋滩涂因其资源丰富且易开发,受到了越来越多的关注。然而,由于过度开发、环境污染及异常海况变动造成海洋滩涂生态正在恶化并日趋加剧。在介绍海洋滩涂主要污染物类型的基础上,本文对海洋滩涂沉积物中污染物的组成、来源、空间分布及污染水平进行概述,列举滩涂污染生态风险评估主要方法,剖析滩涂污染引发的主要问题,总结近年来滩涂治理的思路和措施,旨在为新型沿海滩涂管理及资源开发提供一定的理论基础。

Review on main pollutants in marine tidal flat, China

With the economic development and improvement of living standard, the exploitation and usage of marine tidal flat have drawn much attention, as it is rich in natural resources and easily exploited. However, the marine mudflat ecology has been destroyed due to overexploitation, environmental pollution, and abnormal sea conditions. Based on the introduction of the main types of pollutants in marine tidal flats, the present research does the following: 1) summarizes the main composition, source, spatial distribution, and pollution level of marine beach sediment pollutants, 2) illustrates some major ecological risk assessment methods to assess pollution; 3) mentions problems caused by pollutants; and 4) propose some strategies to control/treat these pollutants. This paper can provide some theoretical bases for management of the new coastal beach and development of resources.
