水利是采用各种人为的工程措施,对自然界的水进行控制、调节、治导、开发、管理和保护,以减轻或免除水旱灾害,并供给人类生产活动和生活必需的水和电。很显然,水利部门是国民经济中一个相对独立的经济部门,其构成主体是生产性的企业和组织。因此,水利是国民经济的一项产业。水利作为基础产业,是因为其在国民经济建设中具有重大作用,对其它产业起着支承和制约作用的支柱型产业。 Water conservancy uses various man-made engineering measures to control, regulate, govern, develop, manage and protect the water in nature so as to reduce or eliminate floods and droughts and provide water and electricity necessary for human activities and production. Obviously, the water conservancy department is a relatively independent economic department in the national economy, and its main component is the productive enterprises and organizations. Therefore, water conservancy is an industry of the national economy. Water conservancy, as a basic industry, is a pillar industry that plays a significant role in the construction of the national economy and plays a supporting and restrictive role in other industries.
