摘要
通过全年的生物量调查的方法，对保安湖的优势种水草生产量进行调查；并进行两个月的优势种水草的分解实验，同时结合各优势水草的含碳量和保安湖的湖水溶解有机碳(DOC)和颗粒有机碳(POC)的动态，阐明大型水生植物在保安湖生态系统碳循环中的作用。同时在整个湖泊范围内，运用分形几何学对水草中的含碳量格局进行分析。
By carrying out the macrophyte biomass investi gation in 1996, we got the annual production of dominated species in Baoan Lake. The Decomposition experiment of dominated species had been done in the lab. On the basis of considering carbonaceous content in the dominated species and the d ynamic of DOC and POC in the water, we elucidated the function of macrophyte in the carbon circulation of Baoan Lake. We also use the fractal geometry and geost atistical analysis to study the pattern of carbon in the macrophyte on a lake sc ale.
