(一)长期以来,由于高扬程灌区存在“水费高,管理费用高、机电维修费用高、群众负担高”的四高问题,因而高扬程的前途始终是一个有争议的问题,也引起了上级有关部门的关注。在此基础上也曾产生过到目前为止仍然颇有影响的一种观点:提水工程应有个限度。扬程超过了一百或一百五十米就不合理了。大量的实例证明,高扬程的合理限度,绝不是也不应是一个简单而绝对确定的扬程标准,而是在获取较高的社会效益前提下,群众对水费所能承受的能力与管理机构维持简单再生产能力的平衡。换言之,只要灌溉效益大,群众对水费负担得起,管理机构通
(I) For a long time, the high lift has always been a controversial issue due to the “high water charges, high management costs, high maintenance costs of machinery and electrical machinery and high burden on the masses” in high-lift irrigation districts. Higher authorities concerned. On this basis, there has also been an opinion that so far has been quite influential: There should be a limit to the water-lifting project.

In other words, as long as the benefits of irrigation are great, the masses can afford the water charges and the regulatory agencies communicate
