项目摘要

Measurements of species composition, biomass and primary production of benthic algae growing on different types of bottom substratum were conducted in Aug. and Nov., 2011, and Mar. and Jun., 2012 along the littoral area in the North basin of Lake Biwa. The biomass of benthic algae at the stations occupied with boulder and cobbles was larger compared to those with sand. At the sandy-substratum stations small filamentous blue-green algae appeared, on the other hand, a few large filamentous green algae dominantly appeared on the boulder, cobble and pebble-substratum stations. Each algal community structure resembled the other among the stations having similar bottom substratum property. The values of assimilation numbers of sandy-substratum stations were slightly higher than those of boulder and cobble-substratum stations. The primary production, biomass and community structure of benthic algae at the littoral area seems to be restricted by difference in the bottom substratum property.

2011年8月和11月，以及2012年3月和6月，对琵琶湖流域北部滨海区不同类型底质底栖藻类的种类组成、生物量和初级生产力进行了测定。卵石和卵石站点的底栖藻类生物量比沙地站点大。砂质底质站出现了小的丝状蓝藻，而卵石、鹅卵石和卵石底质站则主要出现了大的丝状绿藻。在底质性质相似的站点中，各藻类群落结构相似。沙地基地站的同化数值略高于卵石基地站和卵石基地站。滨海地区底栖藻类的初级生产量、生物量和群落结构似乎受到底层基质性质差异的制约。
