Abstract: The Jianghan Plain, taking its name from the Changjiang and Hanshui Rivers. is located between 29°26’ -31°23’N and 111°30’-114°32’E. and has an area of more than 36 000 square kilometers. The Plain. in the central south of Hubei Province. forms part of the Lianghu Plain (the Middle Reach Plain of Changjiang River) and the Donting Lake Plain in Hunan Province. It has a subtropical monsoon climate, with a frost-free period of 243-275 days and a mean annual precipitation of 980-1300mm. Low and flat and crisscrossed by rivers and lakes. it is the major farming area of Hubei Province. known as" ia land of fish and rice". Since the Ming Dynasty. the plain has been one of improtant commercial productive bases of China for grains and aquatic products. In this paper, land types in the Jianghan Plain are classified through the analysis of its physical environmental charactenstics. Some new quantitative methods for the analysis of land type structure are introduced.and the scheme for comprehensive physical regionalization is worked out on the bases of land type structure and the areal differentiation in this plain. 

Key words: Land type, Land type structure, comprehensive physical regionalization. Jianghan Plain
