目前我国的人口数量还在不断增长,农业水灌溉面积也在逐年增加,但水资源却在逐年恶化。严峻的水资源危机要求我们必须采取有效措施,加强对水资源的管理,重视水的节约和有效利用,尤其是合理有效地控制和利用农业、工业和公共溶室等领域的用水,已显得日益紧迫。节约用水,合理控制用水,减少水资源的浪费,不仅是当前急需解决的一个突出问题,也是一项长远的战略任务。 At present, the population of our country is still increasing. The area of ​​irrigated agriculture is also increasing year by year, but water resources are deteriorating year by year.
