Effects of Heated Effluents on the Intertidal Macroalgal Community Near Gori Nuclear Power Plant

摘要: This study is intended to clarify the effects of heated effluents on intertidal benthic marine algal community in Korea. The species composition and biomass algae at discharge canal Gori nuclear power plant southeastern coast Korea were investigated seasonally from February 2001 October 2006. As a result, 54 (7 blue-green, 12 green, 9 brown 26 red algae) found during past six years. In general, number observed was abundant winter spring less autumn. Enteromorpha compressa, E. intestinalis, prolifera Caulacanthus ustulatus common more than 80% frequency period. Seasonal fluctuations mean 1-440 g dry wt m–2 dominant spp. (contribution total proportion 28%), Sargassum horneri (14%) Amphiroa beauvoisii (14%). It evident floristic data that unique micro-environment support different communities those intake or control area. Results large numbers surveys before operation showed that, regions influenced by thermal such as plants, process ecological succession has been proceeded. assumed uni-directional water flow time overhaul largely affect development canal.
