摘要： 目的 观测沈阳市内浑河河段中硅藻数量及种群的变化规律，为法医学溺死鉴定及判断落水地点提供技术帮助与科学证据。 方法 2011年全年对沈阳市内浑河河段布观测点，每月采集水样并观测硅藻数量及种群的变化规律，每周采集水样并观测硅藻优势种群的变化规律。 结果 沈阳市内浑河河段中硅藻数量、种群及优势种群均随时间、地点而变化；硅藻数量及种群数12~2月最低，之后逐渐升高，5月达高峰，略有下降10月达第二高峰期，之后迅速减少；硅藻优势种群4~11月同一采样点相邻两周间变化明显，7~8月同一周内不同采样点变化不明显。 结论 河水中硅藻变化规律复杂，受环境、水文等多种因素影响，在法医学溺死鉴定及落水地点推断过程中，应充分考虑硅藻数量及种群的变化规律。

Abstract: Objection To observe the change rules of quantity and species of diatoms in Hunhe River in Shenyang and to provide technology and scientific evidence for drowning identification and the location of drowning in forensic investigation. Methods In 2011, different locations for collecting water samples were chosen in Hunhe River in Shenyang. Water samples were collected and variation of quantity and species of diatoms were observed every month. And variation of dominant species of diatoms was observed every week. Results The quantity, species and dominant species of diatoms in Hunhe River in Shenyang varied with different time and locations. The quantity and species of diatoms were lowest from December to February and gradually increased, reaching peak in May and second peak in October, and then gradually decreased. The dominant species of diatoms varied significantly adjacent two weeks at same location from April to November, but had little changes at different locations in same week from July to August. Conclusion The change rules of quantity and species of diatoms are complicated and affected by various factors such as environment and hydrology. The change rules of species and quantity of diatoms should be considered in forensic investigation of drowning identification and the location of drowning.
