补充资料：包气带
| 包气带 aeration，zone of 从地下水面到地面的地带。挖井时常见到井壁的上部往往是干的，含水很少。往下挖，井壁逐渐变湿，但井中仍然无水。再向下挖，井壁和井底有水渗出，井中很快形成水面，这便是地下水面。地下水面以上便是包气带，以下是饱水带。按水分分布特点，包气带可分成3个带：① 近地面段为毛细管悬着水带。这个带同大气有强烈的水分交换，水分的增加、减少或消失，同降雨的下渗、土壤的蒸发和植物的散发有关。水分的垂直分布随时间而变化。②毛细管支持水带。地下水面以上由毛细管水上升而形成，在这一带中土壤的含水量自下而上逐渐减少，这个带的深度随地下水位的升降而变化。③介于上述两个带之间的中间包气带。当地下水位深时，中间包气带一般水量较小，变化慢，垂直方向水分分布均匀。当地下水位浅时，毛细管悬着水带同毛细管支持水带连接起来，中间包气带随之消失。 |
