[Abstract]:In this paper, ten large and medium shallow lakes in Jiangxi Province are studied. They are Poyang Lake, Junshan Lake, Pearl Lake, Red Lake, Saihu Lake, Qili Lake, Taipo Lake, South and Northern Lake, Xinmiao Lake and Chen Jia Lake. Phytoplankton and eutrophication were investigated in October 2013 and July 2014. The main results are as follows: 1. A total of 220 species of phytoplankton, including 28 genera and 57 species of cyanobacteria, 49 genera of 122 species of Chlorophyta, 18 genera of 27 species of diatom, 4 species of 4 genera of Phaeophyta, 2 genera of 2 genera of Chlorophyta and 4 species of 4 genera of Prorophyta, were identified in two investigations of 10 lakes. Phylum xanthophyta 2 genera 2 species, Cryptophyta 1 genus 1 species, species composition mainly chlorophyta, followed by cyanobacteria. The brief situation of each lake is as follows: 79 species of phytoplankton 5 phyla, 49 genera, 6 phyla, 67 genera, 94 species, 8 phyla, 76 genera, 122 species, 5 phyla, 50 genera, 84 species, 7 phyla, 83 genera, 142 species, 6 phyla, 55 genera and 88 species of Poyang Lake, South and North Lake, respectively, are identified. There are 101 species of Sihu 6 phyla, 59 genera and 101 species, 7 phyla, 51 genera, 92 species of Taipo Lake, 55 species of 39 genera, 5 phyla of Xinmiao Lake, 99 species of 64 genera, 8 phyla of Pearl Lake. The average abundance and biomass of phytoplankton in Chenjia Lake were 1.03 脳 108 cells / L = 7.656 mg / L and 1.59 脳 10 ~ 7 cells/L,2.134 mg/L, / L, respectively, and 1.67 脳 10 ~ 7 cells/L,2.348 mg/L, in Junshan Lake, respectively. South and North Lake are 9.7 脳 107 cells/L,9.545 mg/L, Poyang Lake 1.13 脳 106 cells/L,0.477 mg/L, Qili Lake 7.87 脳 107 cells/L,8.770 mg/L, Lake and 5.69 脳 107 cells/L, respectively. 6.871 mg/L, Taipo Lake 2.31 脳 108 cells/L,8.436 mg/L, Xinmiao Lake 7.79 脳 107 cells/L,5.820 mg/L, Pearl Lake 1.75 脳 107 cells/L, The dominant species of 1.334mg/L.3.2013 in October (autumn) were diatoms and green algae, and in July 2014 (summer) they were mainly cyanobacteria and green algae. The range of evenness index of phytoplankton in autumn and summer is 0.38-0.74N 0.34-0.74, and the range of Shannon index is 1.2-2.80.22-2.56.4. The ratios of autumn and summer abundance of Shui Hua cyanobacteria to total abundance were 37 -9425 and 95, respectively, and the ratio of biomass to total abundance was 3- 4550 and 18-61, respectively. The characteristics of Shui Hua cyanobacteria in autumn and summer are that the abundance of cyanobacteria is larger than that of biomass, but the proportion of biomass in summer is significantly larger than that in autumn, indicating that the probability of occurrence of cyanobacteria Shui Hua in summer is higher than that in autumn. The transparency ranges from 0.13-1.66 m in autumn and 0.29-1.6 m in summer, and the total nitrogen in autumn ranged from 0.212 to 1.27 mg/L and from 0.670-3.928 mg/L in summer. Total phosphorus ranged from 0.05-0.42 mg / L in autumn, 0.02-0.14 mg/L; in summer, 2.863-8.514 mg/L in autumn and 2.193-23.206 mg/L in summer. The concentration of chlorophyll a was 4.35-100.02 渭 g / L in autumn and 7.76-105.25 渭 g / L 路L ~ (-6) in summer. The eutrophication degree of large and medium shallow lakes in Jiangxi Province in summer is higher than that in autumn. Eutrophication in autumn accounts for 50 lakes, summer accounts for 90. The nutritional status of red lake in autumn and summer was medium nutrition, medium nutrition in Pearl Lake, moderate nutrition in Junshan Lake, moderate eutrophication in Lake Seihu, and mild eutrophication in Pearl Lake. Poyang Lake is medium nutrition, moderate eutrophication; Taipo Lake is mildly eutrophic, moderate eutrophication; Chen Jia Lake is medium eutrophication, moderate eutrophication; Xinmiao Lake is medium nutrition, moderate eutrophication; Qili Lake was mildly and moderately eutrophic, while the South and North Lake were moderately eutrophic and moderately eutrophic. The COD and pH of the lake were positively correlated with the abundance and biomass of Shui Hua cyanobacteria in autumn, the transparency SD was positively correlated with the abundance and biomass of Shui Hua cyanobacteria in summer, and the total nitrogen TN was positively correlated with the biomass of Shui Hua cyanobacteria in summer. The results showed that the increase of total nitrogen in summer could promote the growth and reproduction of Shui Hua cyanobacteria.
