Dynamics of phytoplankton community structure and its controlling factors in Jiulong River Watersheds and Jiangdong Reservoir, Fujian

Abstract

摘要 本文通过现场大面调查,重点测站高频率、长期的跟踪监测等实验手段,以九龙江流域西溪和北溪作为主要研究区域,以九龙江北溪江东库区为重点监测水域,利用显微镜镜检并结合光合色素高效液相色谱分离分析法,以及利用浮游植物功能类群的分类方法对上述区域浮游植物组成及类群空间分布、季节变化及影响因子开展了系统的研究。此外,成功分离培养了2009年甲藻水华原因种--佩氏拟多甲藻(Peridiniopsispenardii),并初步研究了不同N/P比值对其生长的影响。取得如下主要结果: 九龙江北溪不同水文期浮游植物群落结构及其影响因子 分别于2011年枯水期(2月)、丰水期(5月)和平水期(10月),系...Abstract Phytoplankton blooms are becoming more prevalent throughout Jiulong River Watershed, especially in Jiangdong Reservoir over recent years, which are responsible for causing human health problems as Jiulong River is the main source of drinking water supply for Xiamen (Amoy) City, Fujian Province. It is essential to collect data of general structure of phytoplankton community, e.g. its comp...学位:理学博士院系专业:环境与生态学院_环境科学学号:2262009015327
