本文应用遥感原理解释了1986年以来乌梁素海各类型区的变化趋势。指出总的趋势是增加，即1987年以前清水面积增加，1987 ~ 1996年减少，1996 ~ 2002年又增加。但巨型水草区的情况与清水区基本相反，即天然芦苇面积在1987年前减少，1987年后增加;浅水区和沼泽区仅略有增加; 1988年开始种植人工芦苇，面积呈逐年增加趋势。分析了各种变化的原因，阐述了不同类型区的变化与水文气象、水环境因子参数的关系。最后，探讨了乌梁素海水环境可持续发展和可持续利用的技术途径。
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.
