摘要

川中丘陵区地表以紫色沙页岩风化形成的紫色土壤为主

基岩风化剥蚀过程与流失过程交替进行.该区垦殖率高

植被盖度低

地形破碎

土地利用结构复杂

土壤侵蚀严重。根据川中丘陵区的景观特征和土地利用格局

认为地块应为该区土壤侵蚀研究的基本单元;探讨了在不同尺度单元上开展土壤侵蚀监测、评价和预测预报的方法。

Abstract

Soil in hilly regions in them iddle of Sichuan Province ismainly a type of purple soilwhich has been developed from the purple shale rock. The vegetation cover is scattered

and the steep slopes are intensively cultivated

leading to severe soil erosion.In addition

the land use pattern is very complex.The present paper introduced a conception of land block as basic unit for erosion monitoring and the potential multi-scale method for erosion assessment on different spatial scales.
