Other Abstract

研究植被景观对土壤侵蚀的影响对旨在控制水土流失的流域生态恢复工作来说十分重要。该文利用遥感和GIS技术对岷江源头区的农林复合景观和土壤侵蚀强度的变化进行分析,并从景观角度分析了该区域农林复合景观变化对土壤侵蚀强度变化的影响。从不同景观类型对土壤侵蚀强度的控制能力大小看:针叶林>落叶阔叶林>针阔混交林>灌丛>草地>农用地。对于除农用地以外的其他植被景观类型来说,增加其平均斑块面积和形状的复杂性会在一定程度上减少土壤侵蚀强度。而对于农用地来说,斑块形状的简单化以及均匀镶嵌的分布形式则是减少土壤侵蚀强度的有效手段。

The study about the effect of vegetable landscape on the soil erosion is important for the ecology reconstruction which aims at controlling soil erosion.Dynamic variations of agrofforest landscape pattern and soil erosion intensity were analyzed using remote sensing and GIS techniques.And the effects of land scape variation on soil intensity were analyzed from the view of land scape.Taking the mitigating effect on erosion intensity into consideration,landscape classes could be arranged in the order:coniferous forest>deciduous forest>mixed forest>shrub>grassland>cultivated land.At the same time,for most landscape classes,except for cultivated land,increasing the mean patch size and complicating the shape of patch will be helpful to relieve the erosion intensity.However,for cultivated land,simplifying the shape of patch and scattering the patches have the same effect.
