| 摘 要： | 河北省曲周盐演化改造区通过治理改造,土壤环境状况得到极大改善,土壤中蚯蚓种相对较丰富,有3个科、6个属、6个种,正蚓科的赤子爱胜蚓、暗灰异唇蚓和链胃蚓科的日本杜拉蚓在该地区的数量较多.种群密度20.50条/m2,生物量6.01g/m2,基本达到普通农田生态系统的水平;从年龄结构上看该地区蚯蚓种群属稳定型,成蚓和幼蚓量基本相当;全年蚯蚓的数量分布规律是盛夏＞初春＞深秋. |

| Abstract: | Soil environment has been greatly improved through transforming saline alkali land in Quzhou county, Hebei Province. Earthworms in this area are relatively abundant and there are 3 families, 6 genera and 6 species. Allolobophora trapezoides, Eisenia foetida of Lumbricidae and Drawida japonica of Moniligastridae are the dominant species. The average population density of earthworms is 16.53 /m 2, and the biomass is 4.81 g/m 2. This has reached normal level of farming ecosystem. It showed by the age structure that the population structure of local earthworms is in a stable situation. The number of earthworms during the year is in the order of summer>early spring>autum. |
