- Abstract:
- The wind erosion and soil physicochemical properties in afforestation with different years in the Yellow River Floodplain were measured by using the method of ’space replacing time’.The results showed that the depth of soil wind erosion decreased with increasing of the years of afforestation.Wind erosion is the mainly state in the 1-year and 3-year forest land,which belongs to middle degree erosion and light erosion.Erosion-deposition equilibrium was presented by 5-year forestland,slight erosion.Sand accumulated in 8-year forestland.There were different erosion and deposition state of different forestland in different month.Wind erosion is the mainly status in every month in the 1-year forestland,however,in the 8-year forestland,light erosion is the most serious status just in January and February.Soil bulk density and non-capillary porosity reduced with the increase of the years of afforestation.But total porosity,capillary porosity,soil water content and organic matter content appeared an increasing trend with the increase of afforestation years.However,this trend of the afforestation years was slackening off and then reaching a plateau after 5 years.Wind erosion depth,soil bulk density,non-capillary porosity in the middle rows of trees are higher than that of under the tree caused by the terrain,and total porosity capillary porosity and water content appears reserved trend.The results of this research could provide evidence for forest management,wind erosion control and soil improvement.
