放养前后鱼塘沉积物中氮、磷、有机质、色素的变化及环境意义
潘红玺, 胡洪云

摘要:
通过对鱼塘沉积物中营养盐、有机质及色素在放养前后的测试.对比分析了在人类活动(养殖)的影响下,由于鱼塘水体快速富营养化而引起底质上述指标的变化过程,其中快速沉积环境极有利于沉积色素的保存,具有较好的环境营养状况指示意义,同时有机质、色素和营养盐之间存在着密切的相关关系,这为利用色素方法研究短时间序列环境演变,尤其是在近代人类活动影响下的环境变化提供了一定的依据。

Abstract:
Factors and processes such as intense human activities and rapid eutrophication. controlling the concentrations of organic substances, nutrients and organic pigments in sediments were analyzed before and after fish culturing in four fishponds. Results show that rapid sedimentation rate is more favorable for reservation of pigments that can be a significant indicator for trophic state of water bodies. In the meantime, there are close relations among organic substances, nutrients and organic pigments in sediments. These can be useful in sedimentary environmental explanatioa by way of organic pigments index.
Key words:  Fishpond  sediments  pigments
