摘要
从黄土高原的形成过程,黄土-古土壤性征的对比,孢粉、石器、历史、地理以及水土流失的定位观测资料,说明目前黄土高原的严重水土流失是人类破坏植被,不合理利用土地和直接毁灭土壤透水和抗冲能力的结果,而不是一个天然的地质过程。以“28字方略”为中心的水土保持措施是开发整治黄土高原水土资源和治理黄河的根本。
From the course of formation of the loess plateau, the characteristic compari-son between oless and ancient soil, and the location material of spore powder, stone artifact,history, geography and soil erosion, we can see that the present serious soil erosion is not anatural geologic course but a result of the destruction of vegeration, irrational land utilizationand the direct destruction of soil permeability and anti-erosion ability. The water and soilconcervation measure which takes the 28-word principle as the core is the basis to exploitand renovate water and soil resources of the loess plateau and to harness the Huanghe River.
