蚯蚓野外采样方法评述

蚯蚓作为土壤生态系统的关键组成部分，不但可以改善土壤结构，而且与许多生物化学养分循环直接相关，对土壤质量改善和土壤生产力提高起到至关重要的作用.然而，蚯蚓野外采样方法的系统研究和评估还比较缺乏，在国内尤其少见.本文综述了目前国内外常见蚯蚓野外采样方法的操作过程、优缺点、有效性以及对蚯蚓种群特征研究结果可能产生的影响，认为在允许扰动土壤的区域，利用驱虫剂与手拣法相结合进行蚯蚓采样能够较为准确地反映蚯蚓种群和生物量的真实特征；在不能扰动土壤的区域异硫氰酸烯丙酯(AITC)溶液方法是最佳选择.

Field sampling methods for earthworm: A review.

As a critical component of soil ecosystem, earthworm can improve soil structure and relates closely to soil nutrient cycling, playing an important role in promoting soil quality and productivity. However, there is lack of systematic study on the field sampling methods for earthworm, especially in China. This paper reviewed the operational processes of commonly used field sampling methodsfor earthworm, and discussed their corresponding merits, efficacy, and potential influence on research results. To achieve a complete and accurate characterization of earthworm community size and structure, the method of chemical repellentcombined with hand sorting could work well at the sites where physical disturbance was acceptable, while the AITC (allyl isothiocyanate) method would be a favorable option at the sites where soil destruction was not feasible.
