由于大型水庫的修建,对在大型水庫上組織观測水位的問题,提出了新的要求,这和在河流上以及在未經整治的湖泊上組織观測时所提出的要求是不同的。这是因为在水庫上观測水位的最主要的目的,是为了确定水庫的水量,以便研究水庫的水量平衡問题。在很多情况下,用水文測騐的方法來准确地 Due to the construction of large reservoirs, new requirements have been placed on the organization of the observation of water levels in large reservoirs, which is different from the requirements put forward in the organization of observations on rivers and on unreconcealed lakes. This is because the primary purpose of measuring the water level at the reservoir is to determine the amount of water in the reservoir in order to study the problem of water balance in the reservoir. In many cases, hydrological tests are used accurately
