The drivers of global change, including increases in atmospheric CO2 concentrations, N and S deposition, and climate change, likely affect the nutritional status of forests. Here we show forest foliar concentrations of N, P, K, S and Mg decreased significantly in Europe by 5%, 11%, 8%, 6% and 7%, respectively during the last three decades. The decrease in nutritional status was especially large in Mediterranean and temperate forests. Increasing atmospheric CO2 concentration was well correlated with the decreases in N, P, K, Mg, S concentrations and the increase of N:P ratio. Regional analyses indicated that increases in some foliar nutrient concentrations such as N, S and Ca in northern Europe occurred associated with increasingly favourable conditions of mean annual precipitation and temperature. Crucial changes in forest health, structure, functioning and services, including negative feedbacks on C capture can be expected if these trends are not reversed.

大气CO 2浓度增加与欧洲森林营养状况下降相关

全球变化的驱动力,包括大气中CO 2浓度的增加,氮和硫的沉积以及气候变化,可能会影响森林的营养状况。在这里,我们显示出在过去的三十年中,欧洲的森林叶片中N,P,K,S和Mg的浓度分别下降了5%,11%,8%,6%和7%。营养状况的下降在地中海和温带森林中尤为明显。大气CO 2增加氮,磷,钾,镁,硫的浓度降低与氮磷比的增加密切相关。区域分析表明,北欧一些叶面养分浓度(例如N,S和Ca)的增加与年均降水量和温度的有利条件日益密切相关。如果这些趋势没有逆转,则可以预期森林健康,结构,功能和服务的重大变化,包括对碳捕获的负面反馈。
