摘　　要：陷阱法是调查地表节肢动物的主要方法之一,但其诱捕时长和引诱剂类型均会对调查效率和结果造成直接影响。通过对布设不同时长的陷阱进行取样,根据类群数-时长变化曲线,发现随陷阱布设时间增长,地表节肢动物类群数呈先增长后平缓的变化趋势。建议在调查地表节肢动物时陷阱布设时长≥12 d;受到实验目的、人力、物力、时间等因素影响和限制,可适当缩短诱捕时长,但不宜<2 d。通过对5种不同引诱剂类型诱捕效果进行差异分析,发现甘油酒精混合液和糖醋酒精水(1∶2∶1∶20)混合液在内蒙古典型草原地区诱捕类群较为丰富,效果良好。选取最优引诱剂,在保证调查结果可靠、准确的前提下,缩短调查时长,对进一步扩大草原地表节肢动物的调查范围具有重要意义。Pitfall trap is one of the main methods to investigate the diversity of ground-dwelling arthropods. Trapping duration and trapping agent type can directly affect the efficiency and results of investigation. By sampling traps at trapping durations and drawing the richness-time curve, we examined the effects of trap placement time on the trapping efficiency of ground-dwelling arthropods. With the increases of trap duration, the richness of ground-dwelling arthropod increased first and then changed gently. It is suggested that the trapping duration of ground-dwelling arthropods should be longer than or equal to 12 days. Considering the influence and limitation of experimental purpose, manpower, material resources, time and other factors, the duration of trapping can be appropriately shortened, but not less than 2 days. By analyzing the difference of trapping efficiency of five different trapping agents, it was found that the trapping groups in typical steppe of Inner Mongolia were abundant under glycerol alcohol mixed solution, and sweet, sour, alcohol and water(1∶2∶1∶20) mixed solution, showing good trapping effectiveness. It is of great significance to select the best trapping agent and shorten the duration of trapping on the premise of ensuring the reliability and accuracy of the investigation results, which would help expand the investigation scope of grassland ground-dwelling arthropods.
