| 摘 要： | 蚯蚓本研究采用大型土壤动物手拣法和器测法 ,野外调查与室内实验相结合 ,揭示了帽儿山森林生态系统蚯蚓的生态分布规律及其与环境因子的相互关系。水平分布调查表明 ,白桦林的蚯蚓生物量和个体密度远低于其它 3个林型 ;地上垂直分布调查表明 ,蚯蚓生物量与个体密度从山谷到山顶逐渐增多。地下垂直结构调查表明 ,帽儿山地区蚯蚓分布的垂直结构表聚性明显。各种调查均揭示了蚯蚓种群大小随生境条件不同而变化 ,特别是水分条件 ,适合调查地区蚯蚓生存的土壤含水量范围大致为 4 0 %～ 6 5 %。 |

| Abstract: | Lumbricida is the main species of soil animals in Maoer mountain.Employing hand-picking and apparatus-determining methods,and in combination with field survey and indoor experiment,the distribution regulation of Lumbricida and its relationship with environmental factors were investigated.The results showed that the mean population density and biomass of Lumbricida in birch were far less than those of other three types of forests.The average population density and biomass increased gradually from valley to mountain top.The Lumbricida swarmed into the surface soil layer in all sampling months except October.The size of the population changed with different habitat conditions,especially with soil water content,whose fittest range was 40 % to 65% for Lumbricida in the Maoer mountain forest ecosystem. |
