Ecological study on plankton and water quality bioassessment of the Jiulong River Estuary

Abstract

本文以环保公益性行业科研专项“入海河口区水质标准和水环境质量评价方法研究(NO:201309007)”2013年9月~2014年4月4个季节的调查数据为基础,对九龙江口浮游生物的种类组成、时空分布、优势种、环境影响因素等进行了研究;基于环境因素和地理水文概况进行了区域划分,探讨了不同分区浮游生物的群落结构特点并对其水质进行了生物学评价。 主要的研究成果如下: 1、九龙江口浮游植物的种类组成和数量变化 本次调查共鉴定浮游植物150种(含变种和变型),隶属于5门63属,其中以硅藻占主导地位。浮游植物种类数的季节变化趋势为秋季>冬季>夏季>春季,丰度的变化趋势为春季>秋季>冬季>夏季,夏季表层...Based on the samples collected from the four-season survey of Jiulong River Estuary during September, 2013 ~ April, 2014, the ecological characters of plankton were investigated. The species composition, temporal-spacial distribution, dominant species, and environmental factors in the Jiulong River Estuary were analyzed. According to environmental factors and geographical characteristics, the Jiul...学位:理学硕士院系专业:海洋与地球学院_海洋生物学学号:2232012115134
