- Abstract:
- Taking meadow soil in northeastern China as research object,freezing and thawing environment in the test region and the outdoor rainfall erosion process in the spring thaw period were analyzed.The results showed that:temperature generally experienced three stages of cooling,stability and warming,corresponding to the surface soil,it experienced three process of freezing,stable freezing and thawing;Surface soil both experienced freeze-thaw role in the process of freezing and thawing.Late October to early December and middle-late February to early-middle March were the strong period of alternate freezing and thawing effects of the surface soil,especially the melting stage was the critical period to control soil erosion in the spring thaw;after freezing and thawing,soil moisture content decreased by 19%,soil bulk density decreased by 8.9%;The overall soil erosion rates showed an increasing trend;when rainfall intensity was small and thaw depth was shallow,erosion rates increased marginally,slope rill mainly was wide-shallow rill;when rainfall intensity strong,rain erosion rate volatility increase.
