【摘要】 根据野外调查以及收集的数据资料和遥感调查结果得出,2000年山东省水土流失面积3.6×10~4 km~2,占土地总面积的22.9%。从侵蚀强度来看,大多数属于强度和中度水力侵蚀,两种类型的面积分别为1.6×10~4km~2和9.8×10~3 km~2;在山东全省17个城市中,水土流失面积最大的城市为临沂市,有6.1×10~3 km~2,水土流失面积最小的城市是枣庄市,有1.2×10~3 km~2。近十几年来,山东省水土流失状况明显好转,水土流失面积大幅下降,不同侵蚀强度的水土流失面积均有所减少。更多还原

【Abstract】 Based on the obtained data,remote sensing survey and field investigation,the results indicated that there was 3.6×10~4 km~2 farmlands exposed to soil and water loss in Shandong Province in 2000 which accounted for 22.9% of the total land areas. The soil and water loss mostly in the study area belonged to such two types of soil and water erosion as very severity and severi- ty.The areas were 1.6×104~ km~2 and 9.8×10~3 km~2 in Shandong Province,respectively.On the other hand,among the total 17 cities of Shandong Province,Linyi City had the largest area of soil and water loss,with the area of 6.1×10~3 km~2;the least area of soil and water loss,however,distributed in gaozhuang City with the area of 1.2×10~3 km~2.In recent years,the status of soil and water loss in Shandong Province showed better state with the decrease of the areas of different types of soil and water loss.更多还原
