没有森林,地表水的蒸发量将显著增加,引起地表热平衡层和时流层内热分布的变化,地面附近气温上升,降雨时空分布相应发生变化,由此造成降雨减少,风沙增加等气候异常情况发生。森林减少,森林吸收二氧化碳的能力也大大减少了。森林生态系统是物种最为丰 In the absence of forests, surface water evaporation will increase significantly, causing changes in the surface heat balance layer and the tidewater layer. The temperature near the ground will increase, and the temporal and spatial distribution of rainfall will change correspondingly, resulting in the occurrence of climate anomalies such as decreased rainfall and increased sandstorm . Decreasing forests also reduces the forest’s ability to absorb carbon dioxide. Forest ecosystems are the most abundant species
