- Abstract:
- Based on remote sensing data,combined with investigation,the dynamic law of soil erosion is researched,the impact of influence factors on soil erosion is discussed,and the future situation is forecasted.The results indicate that,the soil erosion area accounts for 23.44% of the total area in 2007 in Tongbai-Dabie Mountain Area,and erosion intensity is mild erosion primarily,mainly distributing in south mountainous area,such as Jinzhai County,Huoshan County,the Xinyang municipal district,Tongbai County,Shangcheng County,Xin County and so on.During 20 years the soil erosion area assumes the overall reduction tendency,and increases firstly reduces secondly,and the change difference in different region is obvious.The erosion intensity strengthens firstly and weakens secondly,and transforms from high intensity level to low intensity level overall,but in some area the area of serious and extremely erosion increases,and soil erosion and ecological degeneration is more serious.The degrees of influence on soil erosion by rainfall,soil,slope,vegetation,land utilization way and human activity is different,and it can promote soil and water conservation on one side,and it can also accelerate soil erosion on the other side,and the soil erosion mainly occurs in the farming land,economical forest land and the sparse young growth forest land in which vegetation coverage is relatively few and the slope is relatively big.If the speed can be continued in the next 20 years,the area of soil erosion will reduce annually.
