Abstract

Abstract: To study the distribution of toxic microalgae in surface water of Chuxiong urban area and the algae diversity, after collecting water samples from Longjiang Park, Taoyuan Lake, Flower and Bird Market, Qinglong River and Tongguzhai in Chuxiong City, we used optical microscopes for direct observation and observation after enrichment of water samples to analyze the types and diversity of microalgae in the water. The results showed that the toxic microalgae observed included Houttuynia and Microcystis; In addition, other algae included Chlorella vulgaris, Corydalis, and another 21 microalgae; The simpeson index of algae in each water body is between 0.944 and 0.995, but the Shannon-Wiener index is different greatly. Most of the microalgae in the surface water of Chuxiong urban area are non-toxic algae, and only Anabaena and Microcystis are toxic microalgae. This finding will be beneficial to the effective use of algae resources in Chuxiong urban area and the prevention of water environment safety risks caused by algae.

Key words: toxic microalgae, anabaena, microcystis, microalgae diversity
