子午岭地区自然区域特征及其与土壤侵蚀的关系
- Title:
- The Regional Properties of Natural Environment and Relationship of It and Soil Erosion in the Ziwuling Region
- Keywords:
- the Ziwuling area; regional properties; vegetation cover; soil erosion
- 摘要:
- 在对子午岭地区进行全面考察的基础上，分析研究了子午岭地区区域自然环境的基本特征，指出：子午岭地区地质条件复杂，构造运动强烈、岩性疏松、地貌类型齐全、沟深坡陡、降水丰沛、降雨强度大、冲刷强烈，具备了各科侵蚀过程的发生条件。但由于地面覆盖着良好的植被，侵蚀很轻微。子午岭地区作为黄土高原植被恢复的样板表明，大力恢复黄土高原地区的植被，是黄土高原水土保持的核心和中心任务。
- Abstract:
- The Regional properties of natural environment and relationship between it and soil erosion have been analysed in this paper,using field investigation method.It is pointed out that geological condition of the Ziwuling area is complicated,tectonic movement is violent,geographi eal type is complex,rainfall amount and rainfall intensity are big,and washing action is strong,A1 these provide conditions of occuring severe soil erosion,But because of better vegetation cover on the surface, soil erosion is very slight in the loess plateau.
