在缺水地区,为了保证工农业生产用水和居民生活用水,往往修筑蓄水池、水库等积蓄地面水和雨水。这种办法的缺点较多,例如占地面积大;干旱地区水面蒸发量大;地面径流的泥砂含量大,因沉淀淤积库容会逐渐减小;开敞水面容易受地表污染;蓄水池和水库还是威胁下游地区安全的潜在因素等。因而在条件许可的地区,将水蓄存在地下是较为理想的。地下积蓄地面水和雨水的方法,可分为地面经流自然渗入地下和通过灌注系统灌入地下
In water-scarce areas, in order to ensure the production of industrial and agricultural water and water for residential use, reservoirs and reservoirs are often built to accumulate surface water and rainwater. There are many shortcomings of this approach, such as large land occupation; large surface water evaporation in arid areas; large sediment content in surface runoff, sediment storage due to sedimentation will gradually decrease; open water is easily polluted by the surface; reservoirs and reservoirs Or threaten the safety of downstream areas such as potential factors. Therefore, where the conditions permit, the water stored in the underground is more desirable. Underground accumulation of surface water and rain water can be divided into the ground through the natural infiltration of underground flow through the irrigation system and poured into the ground
