摘要
本文主要从原理、理论上分析研究了黄河上游水土流失与地形、地貌、土质、植被气温以及降雨量等因素的关系,从而初步建立了黄河兰州段上游水流失的预测模型。
This paper studies the relations between the soil erosion and such factors as topography, landform, soil, surface cover,temperature,rainfall,etc. ,so that the model for predicting the soil erosion at the upper section of Lanzhou of the Yellow River is to be established.
