摘  要:
为四洞沟景区生态环境的保护提供依据,2013年8月和2014年9月,采用点线面结合的方式,在四洞沟景区采集藻类植物样本,研究贵州赤水市四洞沟景区藻类植物的多样性及区系特征。结果表明:赤水市四洞沟景区藻类植物共计313种,分别隶属于5门8纲21目30科70属;藻类植物的F指数、G指数、G-F指数分别为14.4695、3.6816和0.7456,与贵州省内周边地区藻类植物多样性差异不显著。其中,气生、亚气生藻类植物种类较多,浮游藻类植物种类较少;藻类植物优势科为色球藻科(Aphanocapsa Nag.)、颤藻科(Oscillatoriaceae Harv.)、伪枝藻科(Scytonemataceae)和丝藻科(Ulotrichaceae),4科共含179种,占总种数的57.19%;优势属为粘杆藻属(Gloeothece Nag.)、粘球藻属(Gloeocapsa Kütz.)、席藻属(Phormidium Kütz.)、颤藻属(Oscillatoria)和舟形藻属(Navicula),5属共有藻类植物95种,占总种数的30.35%;其区系成分以世界广泛分布种及热带和亚热带种类为主,有中国特有蓝藻种类12种,分别隶属于星球藻属(Asterocapsa Chu.)和肾胞藻属(Nephrococcus Y.Y.Li)。

摘  要:
The species diversity and flora characteristics of algae in Sidongguo Scenic Spot were studied by analyzing algae samples from Sidongguo Scenic Spot in August,2013 and September,2014 by means of the point,line and side combination pattern to provide the scientific basis for protection of ecological environment in Sidongguo Scenic Spot.Results:There are 313 species,70genera,30 families,21orders,8classes and 5phyla.F,Gand G-Findex of algae is 14.4695,3.681 6and 0.745 6respectively and there are no significant differences in algae diversity between Sidongguo Scenic Spot and other surrounding areas in Guizhou.Atmogenic algae species and sub-atmogenic algae species are more than planktonic algae species.The dominant families including 179 species of algae are Aphanocapsa Nag.,Oscillatoriaceae H arv,Scytonemataceae and Ulotrichaceae,and 179 species account for 57.19% of total species.The dominant genera including 95 species of algae are Gloeothece Nag,Gloeocapsa Kütz,Phormidium Kütz,Oscillatoriaand Naviculaand 95 species account for 30.35% of total species.The floristic elements are worldwide distribution species,tropical species and subtropical species mainly.12 Chinese endemic cyanophyta species belong to Asterocapsa Chu.and Nephrococcus Y.Y.Li respectively.
