摘要

本研究於2007年3月16日調查南台灣嘉明湖底質與底棲無脊椎動物，共記錄底棲無脊椎動物2綱4目4科6種(taxa)3,375隻，包括雙翅目3種，貧毛綱、毛翅目、鞘翅目皆1種。其次，由不同水深底質分析顯示，深水區底質強熱減量最高，淺水區則有較大底質粒徑與較少粉泥黏土含量。底棲動物空間分布上，貧毛綱動物隨水深增加而數量減少，其他種類則無較明顯的差異。

A preliminary survey of sediments and benthic macro-invertebrates was conducted for mountain Lake Chia-Ming in the southern Taiwan on 16 March 2007. A total of 3,375 specimens of the macro-invertebrates were collected. They were consisted of six taxa: three taxa of the order Diptera and a taxon for each of the three orders Oligochaeta, Trichoptera and Coleoptera. Sediments differed at different depths; the ignition loss was the highest in deep water, and a higher median size particles and less siltclay contents in shallow water. Oligochaetes decreased in density with the increase of depth, while no obvious depth gradients were found for other invertebrates.
