摘要
测定了 72种大型水生无脊椎动物的能量密度 ,其中 6 9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 2 2 .99- 2 5 .0 8kJ/g(干重 ) ,软体动物的能量密度为 16 .72 - 2 2 .99kJ/g(干重 ) ,昆虫及其幼虫的能量密度变异较大 ,为 10 .4 5 - 2 5 .0 8kJ/g(干重 )左右 .
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.
