摘　　要：利用广东省大沙河水库原水进行一系列藻类培养试验,采用人工模拟微宇宙环境系统,控制培养的初始营养因素水平及培养过程中的光照、水深和pH值等生态条件,研究了藻类生长态势与各种影响因素之间的关系.模型的构建采用综合因子法,定量考察了藻生长速率与初始营养状态、光照和温度之间的回归关系,提出绿藻硅藻藻华在迟滞期和对数期的生长速率模型.该模型与藻生物量模型结合可以预测藻类高峰值爆发的时间,通过实验验证,在水温30℃时与实际符合度较好.32 groups of experiments were conducted using water from subsurface water at Dashahe Reservoir of Guangdong Province, China. Under the control of original conditions of the different trophic status, light intensity, water depth and pH values, algae were cultivated within a designed micro-cosmos. The algae growth velocity and the regression were analyzed. It＇s showed that the original total nitrogen （ TN）, the original total phosphorous （ TP）, the water temperature （T） and the light intensity （I） have notable influences on the algae growth velocity. A comprehensive factor model of algae growing velocity in lag phase and log phase is established. Using this model, several experimental water samples have proved a good degree of accuracy at water temperature of 30℃.
