摘要

地理环境的异质性决定了土壤侵蚀景观信息具有水平异质性和垂直异质性特点。景观信息异质性的成因类型有人类活动、地质体结构差异、高程带。根据湖北省土壤侵蚀景观结构的具体特点

建立了土壤加速侵蚀的斑-廊-基模型、土壤背景侵蚀的环-斑模型和综合性垂直分异3类土壤侵蚀景观信息结构模型。模型科学地揭示了不同强度的土壤侵蚀发生区位、致灾因子和土壤侵蚀景观的空间结构特征

通过该模型可以预测土壤侵蚀的发生、发展态势

明确水土保持治理工程区位及区位内的首要治理因子。

Abstract

The information of soil erosion landscape possess horizontal and vertical heterogeneity typicality. The heterogeneity of soil erosion landscape is owing to man's activity

diversity framework of geological body and various altitude zones. The three kinds of model

patch-corridor-matrix model

ring-patch and vertical heterogeneity model are upbuilt based on landscape of soil erosion in Hubei province. The models lay bare the regional location of different grades soil erosion and spatial structural feature

the model can help us to forecast the trend of soil erosion

to have soil and water conservation projects and primary controlling fatcor taped.
