摘要:
地球是个生态系统，人们将储存在其中碳源人为大量释放到大气中，挑战着这个系统的稳态。于是二氧化碳气体在地球这个大的生态系统中浓度持续增长，而其带来了一系列问题，如提高了全球的气温，提升了全球初级生产力，海洋浮游植物大量繁殖、海洋酸化、全球频繁出现藻类的大爆发现象、而且这些问题在不断加剧中。淡水蓝藻由于具有对二氧化碳竞争利用的优势(还有其它优势)，在淡水藻类群体中脱颖而出，大量生长。所以二氧化碳压力可能是导致蓝藻水华大面积、全球性、持续爆发的主要驱动力。
Abstract:
The earth is an ecological system; people released carbon source into the atmosphere, then car- bon dioxide concentration increased in the ecosystem. So it has brought a series of problems, such as increased global temperature, promoted the global primary productivity, marine phy-toplankton blooms, ocean acidification, freshwater algae blooms, and the problems got more and more serious. Competition advantages (and other advantages) of using carbon dioxide, cya- nobacteria stand out from the freshwater algae population and grow quickly. So, Carbon pres-sure is probably the mainly reason that leads to cyanobacteria blooms in global, continuing out- break.
