摘要：本文针对现阶段河套灌区农业面源污染日趋严重、乌梁素海富营养化加剧和水环境变差
的现状，基于“源头控制，过程阻断、末端治理”的湿地治理理念，建议在乌梁素海水环境治理中
综合采用自然生态与人工强化的技术手段，通过在河套灌区原有土质排水沟的基础上增设生态
护坡和控制性建筑物等工程措施构建生态排水沟，最大程度削减排入乌梁素海的污染物总量，
减轻乌梁素海富营养化程度，从根本上改善乌梁素海水环境，并对生态排水沟构建的关键技术
开展研究。

Abstract:In view of the current situation of increasingly serious agricultural non-point source pollution, intensi⁃
fied eutrophication and deteriorating water environment of Ulansuhai Lake in Hetao Irrigation District, this paper pro⁃
poses to adopt natural ecology and artificial strengthening technical means in the environmental treatment of Ulansu⁃
hai Lake based on the wetland management concept of "source control, process blocking and end treatment". By add⁃
ing ecological slope protection and control buildings and other engineering measures to construct ecological drainage
ditch on the basis of the original soil drainage ditch in Hetao irrigation District, the total amount of pollutants dis⁃
charged into Ulansuhai Lake can be reduced to the greatest extent, the eutrophication degree of Ulansuhai Lake can
be reduced, and the seawater environment of Ulansuhai Lake can be fundamentally improved, and the key technolo⁃
