摘　　要：目的建立武汉市中心城区水域春季的硅藻形态及相对构成比数据库。方法 2012年3、4月期间,在武汉市中心城区的主要河流、湖泊、公园水域中共选取32个采水点并进行水样采集,利用数字虚拟切片工作站(OLYMPUS-DotSlide)采集图像,对硅藻进行种属鉴别和计数。结果共检见14种硅藻藻属,各水域所含硅藻种类及相对构成比有所差异。结论本研究结果提高了硅藻的阳性检出率、计数的准确率以及溺死诊断的效率,可为溺死案件中相应水域的硅藻比对提供基础检测平台,为溺死地点的推断提供依据。Objective To investigate quantity and species distribution of diatomaceous in Wuhan central urban waters in spring. Methods 32 water samples were collected from rivers and lakes in Wuhan city. The OLYMPUS-DotSlide was used to obtain images of diatom and identify diatom species. Results 14 species of diatom was found and the diatom species contained in some rivers and lakes were different. Conclusion This study demonstrated the feasibility of digital virtual slice technology to identify diatoms and the database established can be used for investigation of drowning cases.
