臺灣中部山澗底棲砂矽藻之研究

A Study on the Benthic Diatoms Communities of Mountain Streams in Central Taiwan

The communities of benthic diatoms have generally received less attention when compared with the communities of planktonic forms. Lackey (1964) and Patrick (1966) have discussed some aspects about the ecological problems of benthic diatoms. Both of them showed that the type of water mass, depth, rate of current, turbidity, aeration, water quality, temperature, light intensity, and substrate texture greatly affect the pattern of the community of benthic diatoms. To the writer's knowledge, there is no report on the benthic diatoms communities in central Taiwan (Fig. 1). Based on the results of this collection, the writer is trying to describe some characteristics of the benthic diatoms communities of mountain streams in central Taiwan.
