山西省亩均水资源占有量仅２５６ｍ３，比最干旱的以色列国还少１４ｍ３，水已成为山西省经济发展的严重制约因素。因节水事业发展的历史较短，在一些概念和涵义上、试验研究等方面尚未形成共识，作者愿从以下方面提出个人的认识，希望能引起共识、促进节水事业发展：（１）节水涵义；（２）节水涵义的延伸；（３）节水体系与农业节水地位；（４）节水以雨水资源为基点等方面。
Shanxi Province has only 256 m3 of water per mu, which is 14 m 3 less than that of the driest state of Israel. Water has become a serious constraint on economic development in Shanxi Province. Due to the short history of the development of water-saving projects, there is no consensus on some concepts and implications, experimental studies, etc. The authors would like to raise personal awareness in the following aspects in hopes of arousing consensus and promoting the development of water-saving projects: (1) Water meaning; (2) an extension of water conservation meaning; (3) water saving system and agricultural water saving status; (4) water saving with rainwater resources as a starting point and so on.
