2010/12/2
Soil wind erosion is a serious issue in upland fields, because winter fallow treatments produce awful erosions in Kato area, Japan. This research evaluated the abilities of cover crops that planted at...
A New Instrument for Testing Wind Erosion by Soil Surface Shape Change
Wind Erosion Soil Surface Shape Change
2009/12/2
Wind erosion, a primary cause of soil degeneration, is a problem in arid and semiarid areas throughout the world. Many methods are available to study soil erosion, but there is no an effective method ...
液化玉米秸秆基固沙剂控制土壤风蚀试验（Experiment on Sandy Fixation Material Based on Liquefied Corn Stover to Decrease Wind Erosion）
玉米秸秆 液化 聚氨酯 土壤风蚀 固沙剂
2010/5/5
以室内风洞试验机为主要设备，研究了液化玉米秸秆及液化玉米秸秆基聚氨酯作为固沙剂对筑渣土的保护效应。研究结果表明，二者均能粘结土样表面的大小颗粒形成保护层，提高建筑渣土的抗风蚀性；当液化玉米秸秆的喷施量较低时，随着风速的提高，对土壤的保护作用逐渐消失，土壤的侵蚀度迅速增加；液化玉米秸秆基聚氨酯作为固沙剂的效果要明显优于液化玉米秸秆，当其喷施量为120.37g/m2时，起沙风速超过20m/s，当固沙效...

2010/12/2
Soil wind erosion is a serious issue in upland fields, because winter fallow treatments produce awful erosions in Kato area, Japan. This research evaluated the abilities of cover crops that planted at...
Soil erodibility is an important index to evaluate the soil sensitivity to erosion. The research on soil erodibility is a crucial tache in understanding the mechanism of soil erosion. Soil...
Spatial changes of wind erosion-caused landscapes and their relation with wind field in China
2007/8/24
Based on the results of remote sensing investigations of the landscapes of 1995 and 2000, the national distribution of sandy desertified land and its interaction with other landscapes are ...
Abstract: Based on remote sensing and geographic information system, the spatial distribution of nation-wide wind erosion is studied, and the 1:100 000 national map of soil erosion by wind in China is...
