ABSTRACT 
In this paper, the procedure of the regional planning of Wuchang County using aerial photographs and GIS 
. Zong technique are described. By interpretating and analysing the aerial photographs, the land resources of 
Wuchang County, such as arable land, water, forest, traffic and waste land, are investigated. Based on the 
e sequential photographs and auxiliary data, the dynamic change of arable land, water surface and the expan- 
sion of Zhifang town and Jin kou town are analysed quantitatively and qualitatively. According to the fac- 
959. tors of ecosystem, economy and environment, the suitable use of land resources are evaluated, such as the 
; present situation and construction, and the suitable land for planting orange trees are analysed. The data 
987. base of land resources of Wuchang County has been established on micro-computer. The mathematic model of 
land, population and economy are established and the tendency of development are established. 
The results show that a great deal of static and dynamic information can be extracted from airphotos and 
further processed by GIS and that they are very useful for the regional planning, management and decision- 
marking.
