黑龙江中游浮游植物多样性动态变化及水质评价
Dynamics of phytoplankton diversity and water quality evaluation in the middle reaches of Heilongjiang River
摘要
Abstract
The characteristics of phytoplankton were investigated in the middle reaches of Heilongjiang River in May (spring), July (summer) and September (autumn) of 2010. The dynamics of phytoplankton diversity were examined and water quality analyzed using three phytoplankton diversity indices, by gray relational analysis, and by single-factor water quality assessment methods. The species composition of Bacillariophyta was highest in the middle reaches of the river. Phytoplankton were abundant and with high diversity (the value of/Hwas 3.66-3.86 ; the value of J was 0.83-0.88). The lowest values of three diversity indices were measured at two sampling sites (HM-1 and HM-6) in the spring. The diversity of phytoplankton revealed seasonal dynamics, being higher in summer than in spring and autumn. Gray relational analysis indicated that the relational degree was closest to level I of the graded environmental quality standards for surface waters. The calculated values of relational degree were 0.788, 0.903, 0.851, 0.856, 0.864, 0.791 and 0.879 at sites HM-I, HM-2, HM-3, HM-4, HM-5, HM-6 and HM-7, respectively. Combining the gray relational analysis with single-factor water quality assessment methods, and diversity indices, indicated that the water quality was within the OS standard 'clean' in the middle reaches of Heilongjiang River, and that the water quality was level Ⅰ- Ⅱ This quality provides a suitable habitat for rare aquatic species, for spawning of fish and shrimps, or as a feeding ground for larvae. The river could also provide conditions for the restoration of fishery resources and for protection of aquatic resources.关键词
