为了通过较大面积的中间试验,探求黄土丘陵区土地资源的合理利用,从根本上防治水土流失,改善农业生产条件和生态环境,提高农业系统的总体功能,为陕北黄土丘陵区的系统开发和农业自然资源的合理利用提供科学依据和技术措施,并作出区域示范,我所和安塞县人民政府合作,在安塞县茶坊——县南沟八个大队建立了水土保持实验区。通过对实验区农业资源综合考察和农林牧生产规划,使我们深刻认识到:造成该区水土流失严重,农业生产落后,人民生活贫困的根源在于土地利用不合理。
In order to explore the rational use of land resources in the loess hilly region through a large area of intermediate tests, to fundamentally prevent and control soil and water loss, improve agricultural production conditions and ecological environment and improve the overall function of agricultural system, And scientific utilization of agricultural natural resources to provide scientific evidence and technical measures and to make regional demonstrations. In cooperation with Ansai County People’s Government, we established a soil and water conservation experimental zone in the eight brigades of Nangang, Chafang County, Ansai County. Through the comprehensive investigation of agricultural resources and the planning of farming, forestry and animal husbandry production in the experimental area, we have realized profoundly that the root causes of serious soil erosion, backward agricultural production and people’s living poverty in this area lie in irrational land utilization.
