| 摘 要： | 土壤侵蚀分布具有明显的时空变化特征，研究其时空变化规律对于科学地进行土壤侵蚀防治具有重要意义。应用遥感和GIS技术，监测青岛市土壤侵蚀现状和动态变化情况，1995～2000年水土流失面积减少了430．55km^2，并作出了青岛市1995年和2000年两期的土壤侵蚀强度类型动态变化转换矩阵，此成果可为土壤侵蚀防治、政府公告和生态环境建设服务。

| Abstract: | Distribution of soil erosion has obvious characters of space-time change.Researching its space-time change law has important significance for scientific prevention of soil erosion.In this paper,GIS and remote sensing are used to supervise the current status and dynamic changes of soil erosion in Qingdao,The area of soil erosion from 1995 to 2000 had been reduced 430.55 square kilometer,and the transition matrix about dynamic change was devised for soil erosion intensity types of 1995 and 2000 in Qingdao.The results serve as prevention of soil erosion,governmental bulletin and ecological environment construction. |
