摘要: 对山西省辛安泉泉域弧形串珠藻的物候期进行了研究。2005年1月至10月对标本进行了4次采集(每个季节1次),同时对每个采样点的环境因子如气温,水温,流速,pH,溶氧,电导进行了监测和记录。在显微镜下对弧形串珠藻的10个主要形态特征进行了观察和测量。研究结果表明,所有的环境因子都有不同程度的季节变化,而且弧形串珠藻的某些形态特征也表现出了明显的季节变化,在春季生长良好,夏季生长相对较差。同时将环境因子对其的影响也作了相关性分析,结果表明,尽管弧形串珠藻的生长发育在一定程度上受环境的影响,但最主要的影响因素还是其自身的生物发育规律。

Abstract: The phenology of Batrachospermum acuatum was studied. The specimens were collected four times from January 2005 to October 2005(one sampling per season). The air temperature, water temperature, current velocity, pH, dissolved oxygen, specific conductance were monitored at every sampling time. Ten main morphological characteristics of B.acuatum were observed and measured under the microscope. The results showed that all the environmental factors had seasonal patterns to different extent and some of the morphological characteristics had significant seasonal fluctuations, indicating the differences in their seasonality. B.acuatum grew well in spring but not so good in summer. The relationship results showed that despite the development of B.acuatum was affected by environmental factors to some extent, the key factor was its own biological rhythm.

Key words: Batrachospermum acuatum, China, environmental factors, seasonal dynamics, Xin&rsquo, an Spring
