日本山区的水资源量比较丰富,但是由于受气候和地形条件的限制,水资源的开发利用困难。为了提高山区水资源的开发利用率而开展小型、微型水利工程的开发与应用研究是必然选择。对近几十年来,日本研究开发的结构各异、类型多样的山溪取水工程的取水方式进行了介绍;对广泛应用于日本山区多沙性河流的栏栅式取水工程的结构特征、取水特点以及由栏栅式取水工程群与蓄水池(水库)构成的水资源开发利用模式进行了综合评述,为我国同类型山区的水资源开发利用提供参考。
There are plenty of natural water resources in the mountainous areas of Japan, but it is difficulty to develop and utilize the water resources because of the limitation of the climate and topographical condition. In order to enhance the development and utilization rate of water resources in these areas, it is necessary to study on developing small scale or miniature hydraulic engineering. The different structures and diverse types of mountain stream diversion works which were developed in the recent several dozens of years in Japan are introduced, the characteristics of structure and water intake of bar-screen typed mountain stream diversion works which are widely applied in sandy rivers in the areas, as well as the pattern of water resources development and utilization that is based on the groups of mountain stream diversion works and reservoirs are reviewed comprehensively. It is suitable for the water resources development and utilization in the similar mountainous areas of China.
