地处西北黄土高原沟壑区的陇东地区,气候湿润偏旱,自然资源丰富,是甘肃省发展农林牧业的基地之一。长期以来,因多种因素的限制,使该区自然资源遭受破坏,残塬沟壑的风蚀、水蚀尤为严重。多年的以兴修水平梯田为中心的农田基本建设,使该区塬面耕地发生了很大变化,但多数残塬及山地、沟壑仍未得到及时治理,致使自然资源优势得不到充分发挥,土地不能合理利用。
Located in the Longdong region of the Northwest Loess Plateau gully region, the climate is humid and drought-prone with abundant natural resources. It is one of the bases for the development of agriculture, forestry, animal husbandry in Gansu Province. For a long time, due to a variety of factors, the natural resources in the area have been damaged. Wind erosion and water erosion in the gully areas have been particularly serious. The farmland infrastructures centered on the cultivation of horizontal terraces have greatly changed the cultivated land on the plateau in the area for many years. However, most of the remaining highland and mountainous areas and gully have not yet been promptly governed, resulting in the natural resources being underutilized. The land Can not reasonably use.
