透明水循环课堂教具

Create one standalone 3:2 landscape image: a tactile classroom model of watershed, reservoir, treatment plant and river made from transparent colored resin, physically connected. Visual approach: ceramic matte. Keep a single coherent scene with crisp material edges and believable spatial relationships. No collage, no grid, no logo, no watermark, and no readable text.

生成一张独立的 3:2 横幅图像：用透明彩色树脂制作的流域、水库、处理厂与河流课堂教具，各部分水路真实相连。视觉方法采用陶瓷哑光。保持单一连贯场景，材质边缘清晰，空间关系可信；不要拼贴、网格、标志、水印或可读文字。
