摘　　要：　根据1987年以来的TM资料,对内蒙古乌梁素海湿地演化进程进行动态分析,了解到由于大量的农田退水进入乌梁素海造成湖泊水体富营养化,导致大型水生植物遍布全湖,生物量与生物填平作用随之急剧增加,加快了沼泽化进程。本文提出了以机械化方式收获大型水生植物转移氮、磷营养盐,从而延缓乌梁素海沼泽化的主要技术措施。Baded on the data of TM since 1987 the result of dynamic analysis of marshland evolution process of Wuliangsuhai lake revealed that owing to the great amount of drainage water from farmland pouring into wuliangsuhai lake, the lake has been eutrophicated, dense hydrophytes spread the whole lake, the biological amount and biological accumulation dramatically increase,which accelerates the speed of the marsh formation process. A practical technical measures to transfer the nutrient salts of nitrogen and phosphorus contained in the hydrophytes and postpone the marsh formation process by means of mechanization for hydrophytes harvesting was advanced.
