十二、闽江上的工程
闽江流域降水丰沛，源短流急，水量与黄河流域的水量相近，平均每三年就会发生一次超每秒2万立方米的较大洪水，常年必须护岸防洪。早年的闽江护岸加固是利用普通的竹竿插入水中，扎成竹篱笆，形成天然的竹栅栏。二十世纪九十年代，水口大坝的建成，改善了闽江中游激流和险滩的航运状况，促进了闽江上游的水产养殖，为闽江下游的福州抗洪防涝提供了有力的保障。

12. Infrastructures on Minjiang River
The Minjiang River area has plenty of precipitation, which in volume is close to that of the Yellow River basin. But Minjiang is much shorter in length and water currents run rapidly. Every three years on average a big flood would occur, with the water running at more than 20,000 cubic meters per second. Efforts must be made constantly, throughout the year, to consolidate the river bank against flooding. In the early years, the method was to force plant bamboo sticks in the river bottom. The sticks are then tied up and woven into bamboo fence, forming natural bamboo hedge.
The completion of the Shuikou dam in the 1990s has greatly improved the navigation conditions at the rapids and dangerous shores in the middle reaches of the Minjiang River, facilitated aquatic farming at the upper reaches of the river, and provided a strong support for Fuzhou’s flood-combating at the lower reaches of the Minjiang River.
