摘要
调查陕北淡水涡虫，不仅对于深入研究陕北地区涡虫的分类区系及其它内容具有重要作用，而且对本地区大、中、小学动物实验也很有益处。本文通过对陕北淡水涡虫分类和区系的初步调查，发现有两科两属，且通过分析，认为这种动物资源在陕北有一定数量的分布，但有减少的趋势。同时提出对涡虫生境冷涌泉的保护意见。
The classification and district of turbellarians in freshwater in Northern Shaanxi has been preliminary invertigated. Two genera in two families have been founded. It is concluded that there is a certain amount of this animal resource distributing over Northern Shaanxi, but there is a trend of reduction in the amount.Finally, an idea about protection of cold spring, the living circumstance of turbellarians, was suggested. This investigation would be beneficial not only to the studying of the classification, the district and other things of turbellarians in Northern Shaanxi, but also to the Zoological experiments in schools of this area.
