闹德海水库是供给阜新市饮用水的主要水源,近些年来由于植被破坏、缺乏综合性治理,水土流失日渐严重,既影响到水库库区的排沙保容,又影响了当地农业的可持续发展,并严重影响了水体质量,增加了二次水质处理的成本。本文结合当地具体条件,提出了以建造水平梯田、截水沟和田间路三种形式对水土流失进行综合整治,可有效的防止水土流失,减少水质污染。
The Naodehai Reservoir is the main source of drinking water supply to Fuxin City. In recent years, due to the destruction of vegetation and the lack of comprehensive treatment, the soil and water loss is becoming increasingly serious. This not only affects the sediment holding capacity of reservoirs but also affects the local agricultural Sustainable development, and seriously affected the quality of water, increasing the cost of secondary water treatment. Based on the specific conditions in the area, this paper proposes that the comprehensive improvement of soil and water loss should be based on the construction of horizontal terraces, intercepting ditches and field roads, which can effectively prevent soil erosion and reduce water pollution.
