Influence of land-use changes on soil erosion based on geo-information Tupu theory in Zhujiang Delta
This paper improved the traditional method of researching soil loss changes based on land-use dynamic changes,geoinformation Tupu theory was introduced in to study the heterogeneity of soil erosion caused by land-use changes.With the example of Zhujiang Delta,we investigated the land-use changes and soil erosion changes over the period from 1998 to 2006.The results showed:the soil erosion intension aggravated in recent years,the average amount of soil erosion in 2006 was as much as 1.5 times of that in 1998;the change of land-use was the main reason for the change of soil erosion,and the diversity of soil erosion varied obviously with the transformation of land-use patterns;especially,soil erosion changed sharply with the mutual transformation between developing area or sand land and other land-use types correspondingly.
