一、缘起 水是生物之源。作为地球上最大生态系统的森林,也是降水的产物。因此,森林和水之间,就有个生态平衡问题。 森林在发育成长过程中,要消耗一定数量的水份。但森林并不是一个单纯的水份消耗者。更为重要的是,森林能调节天上水、地表水、地下水的正常循环,充当了“绿色水库” First, the origin of water is the source of biological. The forest, the largest ecosystem on Earth, is also a product of precipitation. Therefore, there is an issue of ecological balance between forests and water. In the process of growth and development of forests, it consumes a certain amount of water. But the forest is not a pure water consumer. More importantly, the forest can regulate the normal circulation of sky water, surface water and groundwater and act as a “green reservoir”
