河曲、保德、偏关三县是我省西山二十八县典型的黄土丘陵沟壑区。共同特点是,风大沙多,沟壑纵横,土壤干旱瘠薄,水土流失严重。由于植被覆盖率低,生态失去平衡,风沙、干旱、霜冻、雹灾给农业生产造成很大威胁,产量低而不稳。要彻底改变黄土丘陵区落后贫穷的自然面貌,根本大计在于大力开展植树造林。现结合河曲县基本情况,就这一带的小沟小壕造林,谈谈看法。一、挖潜力,抓紧小沟小壕造林河曲县总土地面积197万亩,其中,宜林面积67万亩。全县水土流失总面积162万亩,占总土地面积的82.2％。县内有县川河、朱家川河、悬沟河、邬家沟河四大流域和 Meander, Prudential, partial off three counties in our province Xixiang twenty-eight counties typical loess hilly and gully areas. Common feature is that the wind and sand, ravines aspect, soil arid infertility, soil erosion is serious. Due to the low coverage of vegetation and the loss of balance of ecology, wind-blown, drought, frost and hail threats pose a great threat to agricultural production, resulting in low and unstable yields. In order to completely change the natural appearance of the backward impoverished people in the loess hilly region, the fundamental plan is to vigorously carry out afforestation. Now with the basic situation of Hequ County, a small trench in this area small trench afforestation, to talk about. First, tap the potential, pay close attention to small trench moat afforestation Hequ County, the total land area of ​​1970000 mus, of which, 67000 acres of forest area. The total area of ​​soil and water loss of 1620000 mu, accounting for 82.2% of the total land area. County County River, Zhujia River, hanging ditch River, Wujiagou four river basins and
