The height of the annual flood crest of the Amazon at Iquitos has increased markedly in the last decade. During this same period, there has been greatly increased deforestation in the upper parts of the Amazon watershed in Peru and Ecuador, but no significant changes in regional patterns of precipitation. The change in Amazonian water balance during the last decade appears to be the result of increased runoff due to deforestation. If so, the long-predicted regional climatic and hydrological changes that would be the expected result of Amazonian deforestation may already be beginning.
过去十年间，亚马逊河伊基托斯段的年度洪峰水位显著升高。在同一时期，秘鲁和厄瓜多尔亚马逊流域上游的森林砍伐面积大大增加，但区域降水模式没有明显变化。过去十年亚马逊水量平衡的变化似乎是由于森林砍伐导致径流量增加的结果。如果是这样，那么人们早已预测到的、亚马逊地区森林砍伐可能带来的区域气候和水文变化，可能已经开始显现。
