{"word":"拦沙坝","introduction":"拦阻河沙、砾石的堤坝。常兴建於水库上游的支流，目的在避免水库快速淤积。这座水库的上游河沙很多，必须兴建拦沙坝，以防水库淤积。","prompt":"An illustration of a sturdy dam constructed to block and control the sand and rocks in a river, typically built on the tributaries upstream of a reservoir. The scene showcases the importance of preventing rapid sedimentation in the reservoir by stopping the flow of sand and rocks. The style is vibrant children's animation, emphasizing the construction and function of the dam with detailed textures and three-dimensional effects. The focus is on the structure itself, surrounded by flowing water and rocky debris, highlighting the concept of '拦沙坝'.","explanation":"这幅插图展现了一座坚固的堤坝，用以拦阻河流中的沙砾，常见於水库上游支流。通过控制沙砾的流动，有效防止水库快速淤积的重要性。画面风格鲜艳，突出了堤坝的建筑和功能，细致的纹理和立体效果突显了主题，周围环绕著流动的水流和岩石碎片，突显了“拦沙坝”的概念。","alt":"拦沙坝的堤坝结构插图","title":"这幅插图展示了一座坚固的堤坝，用以拦截和控制河流中的沙砾。通过控制沙砾的流动，有效防止水库快速淤积，关注点集中在结构本身，周围环绕著流动的水流和岩石碎片，突出了“拦沙坝”的概念。"}
