- Title:
- The District Character and Prevenient Way of Soil Erosion on the Loess Area in the East of Qinghai Province
- 摘要:
- 青海省东部农业区即青藏高原东部边缘黄土地区是全省水土流失最严重的地区，水土流失面积约占全区总面积的50%。强度流失区和中度流失区分别占流失面积的20%和30%，其余为轻度流失区。导致土壤侵蚀发生的主导因素是大陆性气候和起伏悬殊的地形，不合理的人为活动，加剧了现代土壤侵蚀。本文通过综合分析土壤侵蚀的影响因子和形成原因，对本区土壤侵蚀分区和区域特征进行探讨，并结合各区自然条件和侵蚀特点指出了搞好水土保持的有效途径。
- Abstract:
- The east agricultural region of Qinghai Province,the east edge loess area of Qingzang plateau is the most strong erosive area.The area of soil and water loss is about 50% of the whole.The strong erosive area and the middle erosive area are 20% and 30% of the loss area.Therest is light erosive area.The chief facts leading the erosion to occur are the continental climate and great rolling landform.The unrational human activities aggravate the modern erosion. By analyzing compreahensively these facts affecting soil erosion and forming causes of it,this paper inquires the soil erosive part area and the district characteres and points out the effective way of doing soil and water conservation combining the natural conditions and erosive characteres.
