Planktonic Algae Community Distribution and Eutrophication Assessment of Xi Quanyan Reservoir
The distribution and composition of the planktonic algae community in Xi Quanyan reservoir was investigated, it showed the dominant species were diatom and chlorophyta. According to the comprehensive trophic state of the multiple monitoring results of the different sampling points in the entrance, centre and exit of the Xi Quanyan reservoir, calculate the Comprehensive Trophic State Index to gain the average of the whole year: the entrance is 56.2077, the centre is 54.4001, and the exit is 55.1305, which means that the reservoir is in the slight condition. And to analysis of variance for the different sampling points, the F value is 3.548, less than F0.05, which means that the difference of the eutrophication level is not significant among the each sampling points. By the matched data t test, the differences of eutrophication level among the 3 water periods are very significant: wet season>common season>dry season.
