【摘要】 受人类活动和全球变化的影响,河口和近海海域的低氧以及酸化等环境问题日益突出,近年来已成为科学研究的热点问题并受到社会广泛关注。本文通过梳理底栖有孔虫壳貌微观特征对海域低氧及酸化环境指示的研究现状,总结了壳体特征(壳径和壳重)、壳孔特征(密度、孔径、形态)、壳饰(牙突、瘤状物、脐翼)、壳面溶蚀及壳体重新钙化所引起的房室畸变等指标应用的理论基础和方法技术,并分析了影响结果的各种干扰因素,指出了在研究中若干需要注意的问题和研究方向,提出了一些具有可操作性的建议,为更好地将其应用于近岸海域低氧和酸化环境的研究中并推进至地质历史时期此类古环境的演化研究提供参考。更多还原

【Abstract】 The phenomena of hypoxia and acidification in river estuary and offshore areas are increasing influenced by the anthropogenic activities and global change.The problem has being a hot topic in scientific researches and aroused an extensive attention.This is a review about the marine hypoxia and acidification indicated by microscopic features in the benthic foraminiferal tests,and summarized the theoretical basis and methods of these indicators using on the test features(diameter and weight),pore features(density,size and shape),test ornamentation(teeth and/or tubercules,flaps),test dissolution and abnormal tests caused by the recalcification,and identified the interference factors in the results.We have pointed out several problems needed to pay more attention in the future researches,raised some operable advices and research orientations.The paper also aimed to more exactly use the indicators mentioned above in the future studies of our coastal hypoxia and acidification environment,and be used in the similar palaeoenvironmental evolution.更多还原
