摘要:
以安溪县遥感影像为基础，选取高程、坡度、植被覆盖度、坡向、土地利用类型、土壤类型作为评价安溪县土壤侵蚀潜在危险度的因素。计算出各个因素对于土壤侵蚀潜在危险度的得分值，运用特尔斐法（Delphi）与层次分析法（AHP）相结合的方法求出各个因素的权重值，基于ArcGIS 9.2平台上利用数学模型加权平均计算出土壤侵蚀潜在危险度综合得分。研究表明，安溪县全境的土壤侵蚀潜在危险度综合得分值为54，属于强险型的范畴。
Abstract:
With remote sensing image of Anxi county, six factors including altitude, gradient, vegetation coverage, slope aspect, land use type, soil type were used for assessing potentiality of soil erosion. After calculating the value of soil erosion potential danger of various factors and the weights of all factors which were calculated by the Delphi method and AHP method, we can calculated composite score of soil erosion potential danger by using the mathematical model and ArcGIS 9.2 platform. The results indicated that the composite score of soil erosion potential danger in Anxi was 54, which is the high level.
