- Abstract:
- Soil erosion of karst area in Guizhou province become more severe,which has arisen broad attention.The research on the surface soil structure,soil anti-erosion and soil anti-scour in the limestone region of karst area in the middle of Guizhou province shows that arbor forest improve the soil structure and contain important function,the overlay degree of vegetation under the forest has the great influence on the soil structure.The quantitative analysis showed that soil structure is main factor influencing soil anti-erosion and soil anti-scour with both correlate coefficients and regression analysis through the significant test at level 0.01.The protection of vegetation and preventing the stone desertification from turn already urgent.
