摘　　要：１９９３年５月２２日，在绵山清水河设６个采样断面作着生硅藻的采集，研究结果计有２２个属和７３个种、变种和变型，分属２个纲、５个目７个科，其中以极小曲壳藻杰克变种（Ａｃｈｎａｎｔｈｅｓｍｉｎｕｔｉｓｓｉｍａａｖａｒ．ｊａｃｋｉｉ）为主要优势种，以极小曲壳藻强壮变种（Ａｃｈｎａｎｔｈｅｓｍｉｎｕｔｉｓｓｉｍａｖａｒ．ｒｏｂｕｓｔａ）和喙头舟形藻（Ｎａｖｉｃｕｌａｒｈｙｃｈｏｃｅｐｈａｌａ）为亚优势种，ｓｈａｎｏｎ－ｗｅａｖｅｒ指数为３．２６，硅藻群落分布符合对数正态分布，指示水质清洁。By sampling water from six stations in Mian Mountain Qingshui RiVer in May,1993,attached Diatoms were collectal,Through taxonomic study,73 species,varicties and formeof 22 genera were noted. Dominant species were maominly Achnanthes minutissima var.Jackii,subdominant were Achnanthes minutissima var.robusta and Navicula rhynchocephala.Shannon-Weaver was 3.26.The structure of diatom community is conformed to PatrickThe result indicates that the water quality of the Mian Mountain is better.
