嘉陵江中下游地区由于特殊的地理位置,在清末至民国时期社会持续动荡,战乱不断,在这样的背景下,防御性民居建筑迅速发展,成为一种极具地域特色的传统民居样式。根据建筑形态的不同,嘉陵江中下游地区防御性民居大体可分为碉房结合式、寨堡式两大类,并各自发展出多种式样。 In the middle and lower reaches of Jialing River, due to its special geographical position, the society continued to be in turmoil and war continued during the late Qing and the Republican Period. Against this background, the defensive residential buildings developed rapidly and became a traditional residential style with great regional characteristics. According to different architectural forms, the residential areas in the middle and lower reaches of the Jialing River can be roughly divided into two categories, that is, combination of housing and distribution, and Walled Fortifications, and each has developed a variety of styles.
