ABSTRACT

This study evaluates the impact of land use and occupation changes on potential groundwater recharge in a Brazilian savannah watershed. The results show that potential groundwater recharge was directly influenced by changing scenarios in the watershed. The impact of land use and occupation changes was assessed by considering current land use and the replacement of all agricultural crops by soybeans (scenario 1) and natural savannah (scenario 2). We conclude that the processes of land occupation of the watershed should be understood in order to minimize reductions in the potential groundwater recharge in a watershed located in the Brazilian savannah biome.

摘要

这项研究评估了土地利用和占用变化对巴西大草原流域潜在的地下水补给的影响。结果表明，潜在的地下水补给直接受到流域情景变化的影响。土地利用和职业变化的影响是通过考虑当前的土地利用以及用大豆（情景1）和天然稀树草原（情景2）替代所有农作物来评估的。我们得出结论，应该了解流域的土地占用过程，以最大程度减少巴西大草原生物群落中一个流域的潜在地下水补给量减少。
