Abstracts

In order to prived a reference for the ecological study on medium and small size rivers of the world, this paper aimed at supplement the community structure information of aquatic protozoa and assessment on aquatic environmental health of the Yongjiang River. The structures characteristics and the seasonal changes of sarcodina and ciliated protozoan community were investigated and analyzed at 13 sampling sections. The results showed that there were 21 sarcodina species and 64 ciliate species and the different among the protozoan species at sampling sections were obvious. The maximum diversity index H' of sarcodina and ciliated community were less than 2.3. The community similarity among different sections was lower. Community pollution values of protozoan community were between 2.131 to 2.238. It displayed that the Yongjiang River was polluted heavily. Rebundancy analysis showed that environmental factors could promote the abundance of sarcodina and ciliated protozoan. The water quality evaluated by protozoan biological index was in accord with the results from former studies by using other aquatic biological indicators.
