在水生系统中，浮游植物的丰度受到营养物质可获得性的强烈影响。对于温带湖泊，已经清楚地表明，湖泊之间浮游生物叶绿素a浓度(Chla)的变化具有很强的相关性！磷(TP)水平(Dillon&RrGLER 197 4，McCauley等人，草原二人组。(1989年)。进一步的实验操作表明，磷往往会限制藻类的生长(Schindler 1977)。这使得湖泊管理者可以操纵总磷水平来控制藻类的生物量。然而，在RHE Chla-TP关系中仍然存在比管理者希望的更高水平的残余变异性(Carpenter等人)。1985年)。尽管许多研究试图将这种残留变化与其他湖泊特征联系起来(Currie 1990，QuiR6S1990)，但还没有确定一般的解释。
In aquatic systems, phyroplankron abundance is strongly influenced by nutrient availability. For temperate zone lakes, it has been clearly shown that the variation among lakes in plankron chlorophyll a concentrations (Chl a) is strongly relared ro rota! phosphorus (TP) levels (DILLON & RrGLER 197 4, McCAULEY et al. 1989, PRAIRIE er al. 1989). Further experimental manipulations have shown that phosphorus often limits algal growth (SCHINDLER 1977). This has allowed lake managers to manipulate TP levels to conrrol algal biomass. However, there still remains a higher level of residual variability in rhe Chl a-TP relationship than managers might wish (CARPENTER et al. 1985). Although many studies have attempted ro relate this residual variability to other lake characteristics (CURRIE 1990, QuiR6S 1990), no general explanation has yet been identified.
