摘要 对昭通市鲁甸县人工湖、砚池山水库、桃源水库等不同水体中的藻类植物进行采集、观察及分类学鉴定,确定了8门43科105属440种。昭通市鲁甸县藻类植物丰富度比较高,其中绿藻门(16科53属204种)和硅藻门(12科24属148种)占优势。调查区无论是从属的数量还是从种的数量来分析,优势科(13科)多种属(21属)现象都比较明显,构成了昭通市鲁甸县藻类植物的主体。对昭通市鲁甸县的藻类植物进行研究,可补充昭通市藻类植物资源,为地方藻类研究提供可靠数据和资料。

Abstract Collection, observation and taxonomic identification of planktonic algae were conducted in different water bodies such as artificial lakes, Yanchi Mountain Reservoir and Taoyuan Reservoir in Ludian County of Zhaotong City. Eight families, 43 families, 105 genera and 440 species were identified. The abundance of planktonic algae in Ludian County of Zhaotong City was relatively high. Chlorophyta (204 species, 53 genera, 16 families) and diatoms (148 species, 24 genera, 12 families) were dominant. The dominant families (13 families) and multiple genera (21 genera) were obvious in both the number of subordination and the number of species in the survey area, which constituted the main body of algae in Ludian County of Zhaotong City. This paper studies the planktonic algae in Ludian County of Zhaotong City, which can supplement the algae resources of Zhaotong City and provide reliable data for local algae research.

藻類植物是一种自养型生物,主要生活在水体中,其中大多数生活在淡水水体中。在自然界中藻类植物是重要的初级生产者,对维持水生生态系统的平衡有重要作用。在自然界中藻类植物的分布受海拔、气候影响比较大,不同地点间藻类植物的种类和数量差别显著。昭通市鲁甸县的立体气候特点突出,决定了藻类植物分布的特殊性,至今很少有人从事昭通市鲁甸县藻类植物种类的调查及研究。通过对昭通市鲁甸县藻类植物的研究,明确昭通市鲁甸县藻类植物的种类组成和优势科、属等,为地方藻类研究提供理论基础。
环境监测也受到越来越多的重视,生物监测是环境监测的重要内容之一,生物监测中的浮游藻类型及各种指数可综合反映水质,对水体污染的监测具有连续性和综合性作用[1]。……
