In this paper remote sensing principle is used to explain the changing trend of different types of areas in Wuliangsuhai since 1986. It points out the general trend of total water area is increasing, that is, clear water area increased before 1987, decreased from 1987 to 1996 and increased again from 1996 to 2002. However, the case of giant water-grass area is basically opposite to that of clear water area; namely, natural reed area decreased before 1987, but increased after 1987; shallow water area and swamp area only increased slightly; and artificial reeds began to be planted in 1988, presenting an increasing trend in area year by year. Then we analyze the causes for all the changes, and expound the relationship between the changes of different types of areas and the parameters of hydrometeorological and water environmental factors. Finally, we discuss the technical means for sustainable development and perdurable utilization of water environment in Wuliangsuhai.
