| 摘要: |
| 根据2008-2009年的湖泊渔业资源调查,分析松嫩平原20个湖泊鱼类群聚结构特征.结果表明,20个湖泊鱼类群聚由44种鱼类组成,隶属于4目9科34属.21种鱼类的优势度指数在10000以上,17种鱼类为优势种.群聚Margalef指数(dMa值)为0.908-3.096(1.615±0.615),Simpson指数(λ值)为0.090-0.568(0.222±0.110),Gini指数(D值)为0.432-0.910(0.778±0.107),Shannon-Wiener指数(H值)为1.012-2.690(1.878±0.431),Pielou指数(J值)为0.407-0.915(0.777±0.107).dMa值与λ值、D值、H值和J值的相关系数分别为-0.670、0.665、0.867和0.340;λ值与D值、H值和J值的相关系数分别为-0.631、-0.924和-0.896;D值与H值和J值的相关系数分别为0.924和0.896;H值和J值的相关系数为-0.639.总体上,20个湖泊鱼类群聚结构处在不稳定中. |

| Abstract: |
| On investigations of fishery resources during 2008-2009, the characteristics of the structures of fish assemblages from 20 lakes in Songnen Plain were analyzed. From total of 67249 fish individuals and 6773.6 kg fish weight collected in 20 lakes during 2008-2009, we found 44 species of 34 genus, 9 families, 4 orders, which included 107 surveys by gillnet, trawl net and pull net. The index of dominant degree were over 10000 by 21 species that formed-sized fishes by 9 species and small-sized fishes by 12 species. Dominant species were 17 species that formed large-sized fishes by 8 species and small-sized fishes by 9 species. Margalef index (the dMa value) were 0.908-3.096 (1.615±0.615), Simpson index (λ value) were 0.090-0.568 (0.222±0.110), Gini index (the D value) were 0.432-0.910 (0.778±0.107), Shannon-Wiener index (the H value) were 1.012-2.690 (1-878±0.431), and Pielou index (the J value) were 0.407-0.915 (0.777±0.107), The correlation coefficients (λ value) a(the dMa value with the A value, the D value, the H value and the J value were -0.670, 0.665, 0.867 and 0.340, respectively, the λ value between the D value, the H value and the J value were -0.631, -0.924 and-0.896, respectively, the D value with the H value and the J value were 0.924 and 0.896, respectively, and the H value with the J value was -0.639 (P<0.01). The structures of fish assemblages from 20 lakes are not stable overall. |
