摘要

分析了陕北黄土高原区土壤类型

选取分维数、破碎度和优势度等景观指数作为土壤类型格局指标

并利用Fragstats分析了各土壤类型格局指数。将陕北黄土高原区水土流敏感性分布图与土壤类型图

在ArcGIS下经过数据的提取、分析、计算出了各土壤类型的水土流失敏感性值。分析了水土流失敏感性与土壤类型格局的相互关系

结果表明

水土流失敏感值随土壤类型分维数和破碎度的增加而随之升高

却随土壤类型优势度增加而降低。

Abstract

Through analyzing soil type on the Loess Plateau of Nort hern Shaanxi Province

the fractal dimension

fragmentation

and dominance are selected as the indexes of soil type. The indexes of soil type are analyzed using Fragstats and the value of the sensitivity of soil erosion for the soil type is calculated using ArcGIS. The relationship between sensitivity of soil erosion and pattern of soil type is then analyzed. Results show that the value of the sensitivity of soil erosion increases with the increase in the fractal dimension of fragmentation

but decreases with the increased soil dominance.
