摘要: 根据野外初步观察,提出陕能黄土高原北部半干旱边缘地带的侵蚀营力结构问题进行讨论,分析了营力性质构成及营力结构的地域分异,对综合分析本区的土壤侵蚀问题有一定意义。还对研究相对薄弱的风蚀问题进行了初步论述,认为风蚀是本区生产发展的限制性因素之一,亟应采取积极有效的措施予以防止。

Abstract: Based on the fieldwork, this paper deals with the structure of exogenic force in the north terrain of 1oess hi11y gulied p1ateau in north Shaanxi Province. The author thinks that the structure research is a key to recognize the feature of the local landform and its development. The composition and distribution of the structure have been analysed. The 4 types of the districts of the compositional model of the structure of the exogenic force are given as following:
1. Water-Wind-Gravity-Human process,
2. Water-Gravity-Wind-Humau process,
3. Water-Gravity-Human-Wind process,
4. The process of the balanced exogenic forces.
Finally, as an emphasis, the wind erosion is discussed. The author emphazes that more attention should be paid to prevent the wind erosion.
