Aimed at the increasing eco-environmental problems, including water shortage, water pollution, soil salinization, water loss and soil erosion, loss of function of the channel and river, biocenose degradation, etc, which severely infected the sustainable development for irrigation area, the main works in this paper are summarized as followed: constituting the measures of water resources shortages for developing agricultural water-saving technologies and adjusting agricultural structures; constructing the water polluting control and purification system of Mushroom lake: source control and decrement-sewage collection and treatment - channel ecological interception - wetland treatment -reservoir purification; putting forward the systematic projects for soil salinization and water loss and soil erosion of the integrated application of water conservancy agriculture and forestry.; constructing the ecological impervious channel model in west bank, from all of which theoretical bases and technical support for the eco-environmental rehabilitant in Manasi irrigation area were offered. All of these works were based on data collection, technical analysis, on-the-spot investigation, experimental research and technical development about Manasi irrigation area, etc.

通过对玛纳斯河灌区进行资料查阅收集、理论分析、现场勘察、试验研究和技术开发等途径，针对玛纳斯河灌区存在的水资源短缺、水体污染、土壤盐渍化、水土流失、沟渠河道功能缺失、生物群落退化等日益突出的严重影响灌区可持续发展的生态环境问题，制定了发展农业节水技术、调整农业结构的灌区水资源短缺的措施，构建了&源头控制减量-污水收集处理-引水调控-渠道生态截留-湿地生态处理-库区生态净化&的蘑菇湖水污染控制与净化系统；提出水利、农业、林业综合应用的灌区土壤盐渍化、水土流失问题的综合治理方案；构建了西岸大渠生态防渗型渠系模式，为玛纳斯河灌区生态环境修复建设提供了理论基础和技术支持。

It can be concluded that soil erosion intensity was decreased in recent 20 years,but was not steady-going in this period.

区域的水土流失状况是水土流失宏观监测的重点与目的[1]。

On the basis of field investigation about the arbor, shrub and steppe communities in Wuqi county, the authors quantitatively analyzed the vegetation recovery and the relationship between vegetation recovery and soil erosion.

中文摘要：在对吴旗县乔木林、灌木林和草原群落野外调查的基础上，对其植被恢复及植被恢复与水土流失的关系进行了定量分析，结果表明，在吴旗县这样的自然地理条件下，通过退耕还林、封山禁牧，植被完全可以得到恢复，完全可以控制水土流失的发生。

Soil and water conservation monitoring in construction project is of great significance to soil and water loss control.

开发建设项目的水土保持监测工作对于防止新的水土流失具有十分重要的意义。

In this thesis, I generalized and analyzed, from questionnaires and some cases author experienced, some difficulties and problems one may be confronted with during the reviews and enforcements of soil and water conservation plans to serve as references for professional engineers and all other people involved, so that same mistakes will not be made again.

本研究主要藉现场实际例子，将其所发生之问题纪录，予以统整、分类、分析提出解决之道以及建议，以便提供专业技师与相关从业人员参考，避免再犯相同的错误，藉此提升水土保持计画与工程之水平、品质，以及效率，以使整个水土保持计画监督检查管理部份更臻成熟完善。

Based on the measured data of soil and water loss in the monitoring stations in different relief areas in Zhangjiakou, the spatial suitabilities of water and soil conservation measures were researched.

该文以张家口各个地貌类型区水土流失监测站实测数据为基础，研究了该区水土保持措施的空间配置的适宜性。

Official soil conservation started in Iceland with laws enacted by Althing in 1907 on "forestry and soil conservation".
