TRADITIONAL CHINESE REGIONAL ARCHITECTURE

North China: Generally speaking, much of the northern area of China is dry, dusty and barren land. It suffers from continental temperature ranges which cause differences of 65°-70°F between summer and winter. The limited and unpredictable rainfall results in uncertain agricultural output. The Yellow River, which runs through the region, is a determining factor in the lives of the Chinese who live on its banks. The river bed is higher than much of the surrounding land and must be controlled and watched constantly. Under these geographical conditions, the land is often ravaged by the extremes of flood and drought bringing great famines. A large section of the North is comprised of the loess highlands in the provinces of Honan, Shansi, Shensi and Kansu. The soil in this area is of fine yellow-grey grains which have been laid down in thicknesses of from a few feet to two hundred and fifty feet. As the loess is blown into the region from the northwest, it forms vertical cleavages which result in steep cliffs. Not only is the soil extremely fertile, it also holds moisture well and thus in this region of little rainfall, crops can still be grown. The loess soil has also been used by the Chinese to solve their housing problems. A second major region of the North, which is important to this study, is the North China Plain which has been built up from the silt of the Yellow River. The Plain is often raked by severe duststorms from the loess region. Here in this flat land, the Chinese had to devise an architecture which protected them from the harsh extremes in climate.
South China: Throughout the dynasties the Chinese have expanded southward and have developed the valley of the Yangtze River. As early as the reign of Ch'in Shih Huang-ti (221-210 B.C.), the rulers and military forces fought to subdue and colonize the fertile land of the South in order to bring prestige and glory to their thrones. Because of the successive invasions of the barbarians, the Chinese fled to this region to seek peace and a new start. A final reason for the continuous mass migrations to the South was to escape the oppression of the government and the large landowners. The land in the South was very fertile which appealed greatly to the settlers and, in contrast to the North, the South became comparatively more prosperous. In this tropical and subtropical climate the growing season is much longer than in the North and allows for double cropping in most areas. From the beginning the South became a food supplier for the North. The rainfall, especially from typhoons and monsoon rains, is heavy although unpredictable.
