- Title:
- Status of Soil and Water Loss in Shandong Province
- Keywords:
- soil and water loss; erosion intensity; Shandong Province

- 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3.6×104 km2，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1.6×104 km2和9.8×103 km2；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6.1×103 km2，水土流失面积最小的城市是枣庄市，有1.2×103 km2。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。
- Abstract:
- Based on the obtained data,remote sensing survey and field investigation,the results indicated that there was 3.6×104 km2 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 severity.The areas were 1.6×104 km2 and 9.8×103 km2 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 6.1×103 km2;the least area of soil and water loss,however,distributed in Zaozhuang City with the area of 1.2×103 km2.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.
