巩乃斯流域典型灌溉区水土流失预测与防治研究

Forecast and prevention of the soil erosion in typical irrigation district of Kunes River basin

在分析巩乃斯流域自然地理要素和自然水土流失特点的基础上,科学预测了该区典型灌区农田水利灌溉工程对区域水土流失的影响,结果显示:大量新建扩建水利灌溉工程将扰动地貌,破坏植被面积43.96hm2,新增水土流失1619t。根据研究区自身条件和国家相关标准规范,制定了一套科学合理的防治对策,对该区灌溉区水土保持工作提供一定借鉴作用。

Forecasts scientifically the impact of typical irrigated farmland water conservancy on the regional soil erosion on the basis of the analysis of the characteristics of elements of physical geography and natural soil erosion.The results show that： expansion of a large number of new irrigation projects will disturb landscape and destruct the vegetation in the area of 43.96hm2,and cause additional soil erosion reached 1619t.Developed a scientific and reasonable control measures according to the national related standards and the study area＇s condition.It hopes to provide some reference for the work of water conservation in the irrigation area in the future.
