6、多。人们提出了几个假设来解释这一效应，其中包括最近的气候变化，但这个问题仍然存在争议。现在， 一项新的研究工作，将对来自超过500个偏远湖泊和溪流的时间序列数据所进行的分析与一个简单模型结合了起来，发现所溶解的有机碳浓度实际上是与大气沉降物中硫酸盐和海盐含量的下降密切相关。因此， 溶解的有机碳浓度也许正在向19世纪酸雨第一次岀现之前典型的浓度水平回归。2.

8、和。最近一系列研究报告提岀，如果由人类活动造成的二氧化碳生产不加限制地继续下去，那么未来将会发生 严重的海水酸化。以前的研究工作主要针对酸化对各海洋物种的影响。现在，在挪威的Raune Fjord所进行的一项实验研究中，研究人员利用环境尺度的中型受控生态系统对二氧化碳吸收在一个自然群落生态系 统中的效应进行了估计。结果说明，海洋浮游植物的二氧化碳消耗因该气体浓度增加所产生的空间压力而 明显增加，而营养摄取却没有变化。如果这个结果能够应用于整个海洋，那么这一生物反应效应也许就是 大气二氧化碳浓度的一个重要限制因素。3.
