1988年,我们对全省国家管理的205处万亩以上的大中型水库供水及河流引水灌溉工程,进行了老化损坏情况的调查.并与1981年三查三定的资料以及1985年与1986年两次抽样调查的结果进行了比较.表明近几年来全省灌区工程老化严重,而且继续恶化,效益逐年衰减,这对巩固农业生产、增强农业后劲已构成严重威胁.为此,本文提出控制灌区工程老化损坏的对策,供探讨.
In 1988, we conducted a survey on the aging damage of the large and medium-sized reservoir water supply and river diversion irrigation projects managed by 205 counties under the state administration in the whole province, and compared with the data from 1981 to 2003 and the data from 1985 to 1986 The results of two sampling surveys are compared, which shows that in recent years, the irrigation projects in the whole province have been seriously deteriorated and worsened continuously, and their benefits have been declining year by year, which has posed a serious threat to the consolidation of agricultural production and enhancement of agricultural stamina.Thus, Engineering aging damage countermeasures for discussion.
