| 中文摘要: |
| 2013年7月至2014年6月对滆湖控藻网围内、外和工程示范区3个区域浮游植物进行了采样调查,分析了浮游植物的群落结构特征及其与环境因子的关系。共鉴定出浮游植物158种,隶属7门80属。控藻网围内有11种优势种,网围外9种,工程示范区5种,网围内与网围外优势度最大的优势种均为不定微囊藻(Microcystis incerta),工程示范区优势度最大的为螺旋颗粒直链藻(Melosira granulate var. angustissima)。浮游植物现存量网围外 > 网围内 > 工程示范区。两两比较LSD结果显示,浮游植物生物密度年均值在控藻网围内、外存在显著差异(P<0.05),控藻网围内、外与工程示范区则均存在极显著差异(P<0.01)。浮游植物生物量年均值在控藻网围内、外与工程示范区之间都存在极显著差异(P<0.01),但是网围内与网围外则无显著差异。冗余分析(RDA)以及两变量相关分析(Pearson)结果均显示水温、Chl.a、CODMn是影响滆湖浮游植物群落结构的主要环境因子。 |

| Phytoplankton community structure in three regions of Gehu Lake was investigated and analyzed from July in 2013 to June in 2014.The three regions include inside and outside of bio-manipulation pen and demonstration project area. A total of 158 phytoplankton species, belonging to 7 phyla and 80 genera, were identified.There were 11 dominant species of phytoplankton in inside of bio-manipulation pen, 9 dominant species of phytoplankton in outside of bio-manipulation pen and 5 dominant species of phytoplankton in demonstration project area. The main dominant species inside and outside of bio-manipulation pen throughout the year was: Microcystis incerta, and in demonstration project area was Melosira granulate var. angustissima.The order of standing crop is: outside of bio-manipulation pen > inside of bio-manipulation pen>demonstration project area. LSD from multiple comparison showed that density of phytoplankton had significant difference between inside and outside of bio-manipulation pen(P<0.05).Extremely significant difference was found between inside of bio-manipulation pen and demonstration project area(P<0.01), between outside of bio-manipulation pen and demonstration project area(P<0.01). Biomass of phytoplankton had extremely significant differences between inside of bio-manipulation pen and demonstration project area(P<0.01), between outside of bio-manipulation pen and demonstration project area(P<0.01).There was no significant difference between inside and outside of bio-manipulation pen. RDA and Pearson showed that water temperature(WT), Chl.a and CODMn were the main environmental variables affecting the community structure of phytoplankton. |
