| 摘 要： | 在分析滇池生态系统的基础上，从滇池浮游植物的优势种出发，根据各种藻大的生长特性．分别给予不同的温度限制因子，以此推求其增殖速率，并根据不同时期、不同地点优势藻种的构成比，加权出该时段浮游植物总的生长率。这一改进克服了以往模拟计算中把参数取为常数的缺陷．较好地模拟了浮游植物的生长过程和ＴＮ、ＴＰ等水质指标的年内变化情况。

| Abstract: | Based on analysing the ecological system of Lake Dianchi and the growth characteris-tics of algae,the effects of dominent species and temperature factor for the growth rate of algaewere studied. Different temperature limiting factors were given to acquire their growth rate. Thecomprehensive growth rate at every period was weighted according to the dominent algae's com-position in different place and period, thus the defect of taking model parameter as constant isovercome. The growth process of phytoplankton and some important water quality norms (suchas TN, TP) were simulated:uccessfully with the improved ecological dynamic model. |
