Abstract
[Objective]To understand the structural characteristics of the plankton community and its key environmental impact factors in the rivers of Muli mining area,and to provide data support and reference basis for the management and protection of water resources in the mining area.[Method]Collection and analysis of water and plankton in the rivers(Duosuo and Mori)that surround the opencast mine in the town of Muli.[Result]6 Phylum(21 species)of phytoplankton and 2 Phylum(15 species)of zooplankton were collected in the Dosuo River and 6 Phylum(19 species)of phytoplankton and 2 Phylum(9 species)of zooplankton were collected in the Mori River.In both rivers diatoms,green algae and protozoa were the dominant species,and the density and biomass of plankton were quantitatively higher upstream and lower downstream.The Shannon-Wiener,Margalef and Pielou indices for phytoplankton and zooplankton in Duosuo River are 1.64 and 0.58,0.86 and 0.33,0.69 and 0.42,respectively;the Shannon-Wiener,Margalef and Pielou indices for phytoplankton and zooplankton in Mori River are 1.86 and 0.21,0.87 and 0.24,0.79 and 0.36.Water temperature,pH,and nitrogen nutrients were identified as the main environmen-tal factors affecting the structure of the planktonic communities in the Dosso and Mojito Rivers by redundancy analysis(RDA)and correlation analysis.[Conclusion]The ecological protection of water in the Muli mining area should focus on nutrient pollution and strengthen the control of non-point source pollution caused by overgrazing.关键词
