摘要

Abstract

Fourteen stream segments were investigated throughout the Xin’an Spring in Shanxi Province

China in 2004. The variation ranges in stream size

current velocity

discharge

dissolved oxygen

and specific conductance were large. Twenty-two macroalgae species were found in the stream. Major divisions in terms of species numbers were Chlorophyta (59.1%)

Cyanophyta (22.8%)

Xanthophyta (9.1%)

Rhodophyta (4.5%) and Charophyta (4.5%). The most widespread species

Cladophora rivularis (50.0%)

also Oedogonium sp. (42.9%) and Spirogyra sp. (42.9%) were well represented throughout the stream

whereas another 10 species were found in only one sampling site. Total percentage cover varied from <1% to 90%. Red algae Batrachospermum acuatum and the charophytes Chara vulgaris have the highest percentage cover. Among the parameters analyzed

the stream width

specific conductance and dissolved oxygen were the ones that more closely related to the species number and percentage cover of macroalgal communities. The species number of each site was negatively correlated with dissolved oxygen content. The total percentage cover of the macroalgae was negatively correlated with the stream width and the specific conductance.
