Study on the Influence of Typical Land Use Type Change on Soil Erosion Resistance in Northeast Black Soil Region

This paper explores the soil anti-scourability characteristics of land use types in northeast black region, takes surface (0-10 cm) three main (including natural grassland, sylphus pine plantation and cultivated land) typical region as research object, analyzes difference coefficient different types, defines influence physical chemical properties root on anti-scourability. Identify key factors affecting scourability. The results showed that: (1) loss under changed sharply first 2 min scour, gradually stabilized with extension scour time; On whole, grassland was smallest, while that largest. (2) scourability follows: > forest land; Compared after reclamation, anti-scour property Pinus sylvestris significantly improved, reduced. (3) geometric characteristic parameters roots were higher than those vegetation, volume density had greatest effect coefficient. effects diameter classes fine 1.5-2 mm>1-1.5 mm>0.5-1 mm>0-0.5 mm. study can provide a theoretical basis for evaluating consolidation water conservation ability vegetation region.
