摘要

在土壤侵蚀领域内首次提出土壤侵蚀景观的概念。在ARC/INFO软件平台的支持下，采用遥感-地理信息系统一体化的土壤侵蚀强度等级制图方法，获取了土壤侵蚀的图形数字信息，运用图形数字信息对土壤侵蚀景观结构进行了计算。区位商法是城市经济基础理论的代表性方法之一，引用该方法可以定量评价某一土壤生态区的土壤侵蚀水平与大区域的水平间的差异性。基于上述 3个基本事实，对湖北省土壤侵蚀景观的图形信息进行了数据挖掘，对其“多样性”和“区位商”进行计算。结果表明不同的土壤生态区其值相差较大。该定量计算方法的理论意义在于为土壤侵蚀领域的定量研究提供了新方法，其实际意义是可以实现土壤侵蚀分区和治理规划定量化。

Abstract

The notion of landscape of soil erosion is brought forward for the first time. The meansof expression on types of soil erosion and grading of intension is the paper medium long-term in soil erosion scopes. Quantitative study aims at the aspects of soil erosion mechanism and erosion quantity of small catchment or sidehill before. In the course of possession of the digital information on soil erosion figures

the integration of RS and GIS technique is used based on ARC/ INFO. The texture of soil erosion landscape is figured out by the digital information of patterning. The method of the regional location quotient is quoted

which is one of the typical methods on urban economical basic theory. The missdistance of soil erosion between one of soil zoology region with the other region can be assessed. Based on three facts discussing before

the patterning information is analyzed

and landscape diversity and the regional location quotient are calculated. The results show that there are different valuesin different soil ecology region in Hubei province. The method provided the train of new thought for quantitative study in erosion soil scopes

and it makes great sense for valuation in separated soil erosion area of Hubei province.
