摘要
坡度对土壤侵蚀的影响最大,是水土保持工作中首先要考虑的因素之一。用传统方法计算研究区坡度组成和平均坡度的效率低、精度低;而应用ArcGIS软件的空间分析功能对研究区进行坡度分析的效率高、精度高,减少了人为主观因素的影响,为水土保持工作提供一种新技术、新方法。
The slope had the biggest influence on the soil erosion, and it was one of the primary factor in soil and water conservation. The traditional method was low efficiency,low accuracy in the estimation of Mope constitution and average slope,ff we carried on the slope analysis based on ArcGIS to the study area,the efficiency and the accuracy was high,reducing the influence of the artificial factors,making use of the ArcGIS to carry on the slope analysis was a new kind of technique,new method for the water and soil conservation.
