摘要
蓝藻在植物界中的分类地位是最为低等和原始的,其分布范围极为广泛。近年来,蓝藻在渔业生产、生物固氮、环境保护和监测以及植物分类系统的研究中,表现出愈来愈重要的作用。作者自1981～1989年的秋季,在呼和浩特市地区选择了十几个采集点进行采集,初步对呼和浩特市地区秋季淡水蓝藻进行了系统的调查与分类研究,这项工作在内蒙古尚为空白。根据这项研究,呼和浩特市地区秋季淡水蓝藻共有3个目,4个科,17个属,26个种,其中有7个种作为存疑种,尚需进一步研究。
Blue algae are some primordial plants and their status on systematic botany is lowest. They distribute over an extensive area. Recently, blue algae become more and more important in fishery, biological azotification, environmental protection and the research of classifying system. From 1981 to the autumn of 1989, a lot of specimens were collected in more than ten different qlaces in Huhehot region and the autumnal blue algae living in fresh water were classified systematically by author. This work has not been done before in Inner mongolia Autonomous Region The autumnal blue algae living in fresh water in Huhehot reging belong to 3 orders, 4 families, 17 genera and 26 species in terms of this research. These species include 7 ones that can not be named temporarily.
