《宿淮阴南楼酬常伯能》是唐代诗人皇甫冉创作的作品。以下是对该诗的译文、诗意和赏析：

宿淮阴南楼酬常伯能

太阳西下，我宿在南楼上，以此答谢常伯能。
楼上乔木葱茏，下面是一片被废弃的城池和古老的渡船码头。
江湖之外的原野风初入室内，窗中海上的月亮早已知道秋天的到来。
远眺河波浩渺，一眼望去千里无垠，草原之上，牧笛响起三声，仿佛百般忧愁都被唤醒。
站在此地，等待整夜，却没有一个客人过来，我烦恼地请求你，快步穿过寂静的夜晚，来与我相会。

译文：
宿淮阴南楼回谢常伯能，
淮阴日落上南楼，乔木荒城古渡头。
At the southern tower of Huaiyin, I stay and thank Constant Gentleman,
As the sun sets, I rest at the southern tower, where tall trees flourish; below is an abandoned city and an ancient ferry crossing.

浦外野风初入户，窗中海月早知秋。
Outside, the wild wind enters the house, and through the window, the moon over the sea already knows it's autumn.
The wind outside brings the scent of the wild, and through the window, the sea's moon has sensed the arrival of autumn.

沧波一望通千里，画角三声起百忧。
Looking across the waves, I can see thousands of miles; the sound of a horn rises, awakening countless worries.
Gazing upon the boundless waves, I can see a thousand miles; the sound of a horn rings three times, bringing forth countless worries.

伫立分宵绝来客，烦君步屐忽相求。
I stand alone throughout the long night, no visitors arrive; I anxiously implore you to hurriedly come, wearing your clogs.
Standing alone throughout the night, no visitor arrives; I anxiously ask you to step forward, wearing your clogs suddenly.
