Study on the Present State of Soil Erosion in Daqing Area and the Countermeasures

With the economy developing,the ecological environment of Daqing has deteriorated badly in recent years.The soil erosion is very serious.The desert and alkaline land area is expanding year by year.The prairie area diminishes and the yield decreases.Grass quality drops obviously.The recessive succession of vegetation occurs.This paper analyzes the factors of soil erosion in Daqing area.The analysis indicates that the climatic conditions are the primary factor of soil erosion.The irrational resource utilization has also accelerated the corroded progress and aggravated the harm degree.The feasible countermeasure was put forward: chooses the appropriate pioneer species to carry on the vegetation repair.
