摘要
选取高程、坡度、坡向、植被覆盖度、土地利用类型和土壤类型这6个指标,用于评价帽儿山实验林场的土壤侵蚀潜在的危险性。利用ArcGIS软件对各指标属性值进行处理后获取各指标得分数据,消除因量纲不同所造成的影响,利用层次分析法确定各影响因子的权重,加权计算得到帽儿山实验林场的土壤侵蚀潜在危险性综合得分。研究结果表明:该地区土壤侵蚀潜在危险性较低,无险型、轻险型占主要地位,危险型和强险型面积较少,无极险型存在,整个区域平均属于轻险型的范畴。
A total of six indices including elevation,slope,aspect,vegetation cover,land use types,and soil types were selected to evaluate the soil erosion potential risk of Maoershan Experimental Farm. The attribute values of the indices were processed using ArcGIS software and the score of every index data was obtained in order to eliminate the influence caused by different dimensions. The AHP method was used to determine the weights of the affecting factors to compute the comprehensive score of the soil erosion potential danger in Maoershan Experimental Forest Farm. The results showed that the study area had lower risk in soil erosion,which was dominated by no risk type and light risk type. There were less great risk and strong risk area and there was no extreme risk type. Therefore,the soil erosion potential danger of the whole Maoer mountain belongs to light risk type category.
