摘要:

利用遥感原理对乌梁素海1986年以来湿地环境的演变进行分析,指出近17年来乌梁素海总水域面积呈增加趋势;明水区面积1987年以前趋势增加,到1996年趋势减少,至2002年又趋势增加;密集水草区面积与明水区面积变化特征基本相反;芦苇区面积1987年以前趋势减少,而后趋势增加;浅水区和沼泽区面积的总趋势尽管微弱增加,但变化基本平稳;1988年开始种植人工芦苇,其面积呈逐年上升趋势。文章还分析了这些变化的原因,阐述了不同类型区面积与水文气象因子和水环境因子的对应关系,最后探讨了乌梁素海水环境可持续发展和永续利用的技术途径。

Abstract:

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.
