太湖流域低洼地区,为了防止洪水淹没农田,自古以来就采用修筑圩堤的办法,将土地分片包围起来,称做“圩”,圩内除了陆地外,还包括河网和湖荡等水面积,它起着水上交通、调蓄雨水和灌溉水源的作用。自从有了电力排灌站后,圩内水面积的排灌作用就更加得到充分发挥,但实践中遇到一个问题,圩内水面积比重多大为宜?我们认为水面积比重并非越大越好,而是和排涝标准、排涝动力大小、圩内水面积的预降深度等因
In the low-lying areas of the Taihu Lake basin, in order to prevent flooding of farmland, the construction of levees has been adopted since ancient times to enclose the land in slices and called “polders”. In addition to land, the polders also include water areas such as river networks and lakes , It plays the role of water traffic, regulating rainwater and irrigation water. Since there was a power irrigation and drainage pumping station, the irrigation and drainage of the water area in the polder is more fully utilized. However, in practice, we have encountered a problem, what is the appropriate proportion of the water area within the polder? We think the proportion of the water area is not as large as possible, but rather And drainage standards, drainage power size, pre-draw depth within the water area and other factors
