摘要

洱海是云南省第二大淡水湖泊,浮游植物作为湖泊的初级生产者对湖泊状况有重要指示意义.通过对洱海12个月藻类组成的调查分析,发现洱海藻类主要由绿藻门、硅藻门和蓝藻门组成,其中蓝藻门的微囊藻属和硅藻门的脆杆藻属是全年的优势属.藻类丰度和生物量随时间和空间出行显著变化,其中以秋季和南部区域最为丰富,这种时空变化特征与季节、地表径流、人口分布等多种环境因素相关.并对藻类的生长条件以及过生长后发生的水华现象进行了详细分析,随后针对洱海藻类的恢复提出了详细复现方案.这为进一步认识洱海生态系统,实施湖泊保护管理提供了科学依据.

Abstract

Erhai Lake is the second largest freshwater lake in Yunnan Province.As the primary producer of the lake,phytoplankton plays an important role in the status of the lake.Through the investigation and analysis of algae composition in 12 months in Erhai Lake,it is found that algae in Erhai Lake are mainly composed of chlorophyta,Diatom and cyanophyta,among which Microcystis of cyanophyta and Phlebothrix of Diatom are the dominant genera throughout the year.The abundance and biomass of algae varied significantly with time and space,especially in autumn and the southern region.This spatial and temporal variation was related to various environmental factors such as seasons,surface runoff and population distribution.The growth conditions of algae and the phenomenon of blooms after overgrowth were analyzed in detail,and then a detailed reproduction plan was put forward for the recovery of algae in Erhai Lake.This provides a scientific basis for further understanding of Erhai lake ecosystem and implementing lake protection and management.
