中文摘要：

本文通过与《金汴京（开封）皇宫考略》一文进行商榷，提出如下观点：北宋东京皇宫分为皇、宫二城，宫城周长五里，皇城周长九里三十步（或十三步），并从南、东、西三面包围宫城；其皇宫结构与周长，为金代开封皇宫所沿袭，金重修宫殿，并非外扩皇宫；北宋东京皇城正南门为宣德门，位于今开封市新街口处，并未脱离皇城。

英文摘要：

The present paper discusses the article ＂Study of the Imperial Palaces in the Jin Period Bianjing （Kaifeng） . ＂ It points out that the imperial palaces in the Northern Song Period East Capital were divided into the imperial city and the palace-city. The lat- ter had a circumference of five li, while the former nine li and 30 （ or 13 ） steps, surrounding the latter on the southern, eastern and western sides, and the structure and circumference of the two parts were followed by the imperial palaces of Jin Period Kaifeng, with almost all palaces rebuilt but without outward expansion of the original imperial palace area. The main southern gate of the imperial city in Northern Song Period East Capital remained at present-day Xinjiekou of Kaifeng City, not separated from the imperial city.
