摘要
测定了72 种水生无脊椎动物的干湿重比,其数值一般为0.1~0.3,只有少数外骨坚硬骼的种类干湿重比超过0.3.同一物种在不同地点和不同季节,其干湿重比存在差异,周年变动范围为10 % 左右.软体动物软体部分干湿重比。
The ratios between dry and wet weight of 72 species of aquatic macroinvertebrates were measured. The most of them were in the range from 0.1~0.3; a few species with firm exoskeleton had ratios higher than 0.3. Populations from different localities of the same species vary a little, even the same species from the same sites differs with changes of season by a deviation of ±10%. In mollusks, the ratios of younger ones are much larger than those of older ones in the same species.
