利用辩证法的联系观点、发展观点、对立统一观点,分析了黄土高原的水土流失。自然地理要素的相互作用是其动力机制;量变逐渐积累导致质变的恶性循环是其发展过程;人地矛盾是当地的主要矛盾;人类的不合理活动是内在的原因。黄土高原脆弱而敏感的地理环境使水土流失尤为显著。治理水土流失应统筹各种矛盾,兼顾经济效益和环境效益,生态优先,因地制宜。
Using the dialectical connection point of view, development point of view and opposites unity point of view, this paper analyzes the soil and water loss in the Loess Plateau. The interaction of natural geography elements is its dynamic mechanism; the gradual accumulation of quantitative change leads to the vicious cycle of qualitative change; the contradiction between human and nature is the main contradiction in the region; and the irrational human activities are the internal causes. The fragile and sensitive geographical environment of the Loess Plateau makes soil erosion particularly significant. Soil and water erosion should be managed all kinds of contradictions, taking both economic and environmental benefits, ecological priority, according to local conditions.
