| 摘 要： | 为了解不同沉陷程度农田土壤生态系统中大型土壤动物群落结构,于2007年夏季对我国中部潞安集团井工开采区沉陷农田生态系统中不同等高线处大型土壤动物群落组成进行了调查,采用野外手捡法共采集大型土壤动物477只,隶属于3门7纲15目22科。其中,蜘蛛目、鞘翅目、直翅目和膜翅目为优势类群,占总捕量的83.64%;常见类群4类,占总捕量的13.22%。研究结果表明:不同沉陷程度对农田大型土壤动物个体数、类群数均有不同程度影响,农田大型土壤动物个体密度随着沉陷深度的增加呈现增加趋势,沉陷区土壤生态环境的变化引起大型土壤动物的局部迁移。Jaccard相似性系数表明沉陷区中部(2 m、4 m和6 m等高线处)三者间相似程度较高,正常农田(CK)与沉陷区底部(7 m等高线处)之间相似程度最低,达到极不相似程度。研究认为不同沉陷程度对大型土壤动物的群落结构有明显影响,将大型土壤动物作为沉陷区农田土壤质量评价中生物性状指标具有重要意义。 |

| Abstract: | Soil fauna, as an important form of soil ecosystem, can be used as a proxy for soil ecology in characterizing eco-environmental changes. Soil macro-fauna community structures in different soil ecosystems in coal mining subsidence areas of central China were investigated in the summer of 2007. A total of 477 individual soil macro-fauna were hand-collected in the field and classified into 22 families, 15 orders, 7 classes and 3 phyla. The dominant groups were araneae, coleoptera, orthoptera and hymenoptera, amounting for 83.64% of total collected macro-fauna. About four common groups accounted for 13.22% of the total fauna. Results showed a significant effect of coal mining subsidence on the individual density and group number of soil macro-fauna communities. Individual density significantly increased with increasing depth of subsidence. Change in soil eco-environment of subsidence areas triggered local migration of soil macro-fauna. Jaccard coefficient analysis showed high similarity among soil macro-fauna communities in 2 m, 4 m and 6 m depths. The lowest observed similarity was between common farmlands and bed soils of subsidence regions. The findings suggested that soil macro-fauna communities were strongly influenced by land subsidence. It was important to introduce soil macro-fauna to improve soil biological quality and assessment in subsidence farmlands. |
