| 摘要: |
| 测定了 72种大型水生无脊椎动物的能量密度,其中 69种是第一次测定.底栖动物的能量密度随物种、季节、地区、年龄等的不同而存在差异.绝大多数寡毛类的能量密度为 22.99-25.0 8kJ/g(干重),软体动物的能量密度为 16.72-22.99kJ/g(干重),昆虫及其幼虫的能量密度变异较大,为 10.45-25.08kJ/g(干重)左右. |

| Abstract: |
| Energy densities of 72 species of macroinvertebrates in China were measured with microcalorimeter, among which 69 species were first calculated.The energy densities of oligochaetes were 22.99-25.08 kJ/g (dry weight), those of molluscs were16.72-22.99kJ/g (dry weight), and those of insects and their larvae varied markedly, with the range from 10.45 to 25.08kJ/g (dry weight).The density of a species differs to some extent with the changes of season, locality and age. |
