摘要：本文回顾了乌梁素海湿地近20年来富营养化的研究成果。乌梁素海湿地富营养化主要状况表现为:(1)水体氮、磷平均含量已超国家地表水环境质量标准Ⅴ类要求;空间分布上,总体特征为北高南低,西高东低,局部特征则与植物分布有关;时间分布上,总体受河套地区退水和气温变化影响,局部受植物生长影响。(2)沉积物氮、磷显著富集,氮含量在水平方向上北高南低,西高东低,垂直方向上随深度增加而递减,磷含量则无一致规律。(3)藻类时空分布与氮、磷表现出较为一致的规律。近年来,藻类的过量繁殖常导致"黄苔"暴发。(4)水体有机质显著富集,与氮含量空间分布特征一致。(5)沉积物有机质主要来源于陆源输入和水生生物,与氮具有显著的同源性且空间分布特征一致;沉积物有机质显著富集,成为重要内源污染源。今后应加强乌梁素海湿地富营养化机理研究,为乌梁素海湿地恢复提供科学依据和技术支撑。
The research progress of Wuliangsuhai wetland eutrophication over recent 20 years was reviewed. The eutrophic status of Wuliangsuhai wetland was summarized as follows ： （ 1 ） The av- erage contents of nitrogen （N） and phosphorus （P） in waters exceeded the V grade of China National Surface Water Quality. Overall, the N and P contents were spatially higher in north and lower in south, and higher in west and lower in east. Locally, the features of spatial distribution were related to plant distribution. The overall characteristics of temporal distribution were influ- enced by the influent from Hetao region and air temperature. （2） N and P were enriched in sedi- ments. In horizontal direction, the N content in sediments was higher in north and lower in south, and higher in west and lower in east. But the P content did not show any pattern. （3） The tempo- ral and spatial distributions of algae were similar to that of N and P. In recent years, the exces- sive reproduction of algae often resulted in the bloom of Huangtai algae. （4） The organic matter in waters was significantly enriched and positively correlated with the N content spatially. （5） The organic matter in the sediments was mainly derived from terrestrial inputs and aquatic organ- isms. It had significant homology with N, being consistent with N in spatial distribution. The organic matter in the sediments was enriched significantly and became an important source of endogenous pollution. In future, studies on the mechanisms of eutrophication of Wuliangsuhai wetland should be strengthened, which may provide theoretical basis and technical support for the restoration of Wuliangsuhai wetland.
