Community Structure of the Phytoplankton and Its Relationship with Environnental Factors in Lower Reaches of the Yellow River
摘要
Abstract
[Objective] The research aimed to study community structure of the phytoplankton and its relationship with environmental factors in lower reaches of the Yellow River. [ Method ] From April to June in 2011, phyioplankton was conducted qualitative and quantitative researches in Lijing in lower reaches of the Yellow River. By combining population characteristics of the phytoplankton, its relationship with environmental factors was discussed. [ Result] 114 species and 5 phylum of phytoplsnkton were observed in the whole river section. The abundance of the phytoplankton was 0.90 × 104 -303.35×104 ind/m3, and mean was 27.20 × 104 ind/m3. The biomass of the phyloplankton was 0.008 -5.890 mg/m3, and mean was 0.641 rng/m3. Shannon-Weaver diversity index, Pielou evennese index and Simpson's diversity index were respectively 1.59, 0.36 and 0. 55. SPSS data analysis indicated that transparency was uppermost environment factor affected the phytoplankton abundance. Phytoplankton abundance had positive correlation with transparency, and the regression equation was y = - 393. 8 + 115. 5x -11. 1x2+0.35x3(n = 18, R2 =0.952, F = 92.665, P<0. 01). [Conclusion] Tne community structure of phytoplankton, was unstable, and transparency was the uppermost environmental factor affected phytoplankton abundance in the lower reaches of Yellow River.关键词
