| 我国是世界上远盲蚓属蚯蚓分布最多的国家，明确该属200余种蚯蚓在我国的地理分布和生态适应性对蚯蚓的生态功能研究具有重要意义。本文以历史资料记载的物种和本研究团队2006至2016年间实地调查获取的样本为研究对象，通过全面采集该属物种的地理分布信息，绘制了远盲蚓属蚯蚓在我国的分布图。此外，通过提取各分布点对应的生物气候数据，使用主成分分析的方法揭示了影响远盲蚓属蚯蚓在我国区系分布的气候因素。结果表明：（1）远盲蚓属蚯蚓在我国的分布现状主要受水分和温度的影响，在水分因子中，极端水分条件、水热是否同步和年降水量均同等重要，在温度因子中，影响程度由高到低为，极端温度、水热是否同步、平均温度；（2）水热条件较好的区域（例如，华南区）比水热条件相对短缺的区域（例如，华北区和西南区）更有利于远盲蚓属蚯蚓的分布。 |

| The most abundant Amynthas earthworm species was located in China. It is critical to shedding light on the distribution and ecological adaptability of Amynthas for exploring earthworm ecological functions. The previously reported Amynthas species and our own collected species during 2006﹣2016 were studied. The distribution information was gathered for all the specimens, and the Amynthas species distribution map was drawn (Fig. 1). The bioclimate parameters were extracted from the worldClim website following a Principal Component Analysis to clarify the key factors which affect the geographical funa of Amynthas in China. The result shows: (1) The precipitation and temperature are the crucial aspects. The influence magnitudes of precipitation factors were equivalent. The order of affection under the temperature aspect is extreme temperature hydrothermal synchronization > annual mean temperature (Appendix 1); (2) The areas with better hydrothermal conditions (e.g. South China Region) are more conductive to the distribution of Amynthas than those with poorer hydrothermal conditions (e.g. North China Region and North China Region) (Fig. 2). Our results suggest that there are still numerous Amynthas new species waiting to be discovered, and new species records reported in the novel area is exceedingly useful. Importantly, the precipitation and extreme temperature produce the most significant effect on the distribution of Amyntas species which tremendously developed in South China Region due to the perfect ecological suitability. |
