A STUDY ON THE APPLICATION TO REGIONAL PLANNING IN REMOTE SENSING AND GIS TECHNOLOGY

摘要

In this paper, the procedure of the regional planning of Wuchang County using aerial photographs and GIS 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 sequential photographs and auxiliary data, the dynamic change of arable land, water surface and the expansion of Zhifang town and Jin kou town are analysed quantitatively and qualitatively. According to the factors 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 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 decisionmarking.
