安塞县水土保持实验区,位于延安市西北35km黄土丘陵沟壑区第二副区。区内沟壑纵横,地形破碎,土质疏松,植被稀少,耕垦指数大,暴雨多,年输沙模数约14kt/km~2。解放后水土保持工作取得了一定成绩。但以往的治理工作措施单一,缺乏综合治理,治理速度较慢。当地广种薄收的习惯还没有根本改变,因而农业生产水平很低,群众生活困难。
Ansai County Experimental Soil and Water Conservation Area, located in Yan’an City 35km Northwest Loess Plateau hilly and gully area second vice district. Longitudinal and ravine areas, crustal terrain, loose soil, sparse vegetation, cultivation index, heavy rain, the annual sediment transport modulus of about 14kt / km ~ 2. After the liberation of soil and water conservation has made some achievements. However, the previous measures for governance were single, lacked comprehensive governance and slowed down the governance process. The habit of wide variety of thin harvests in the country has not fundamentally changed yet, so the level of agricultural production is very low and people’s livelihood is difficult.
