摘要
东北黑土区是我国重要的粮食产区,但近年来随着水土流失的不断加剧,土壤肥力也不断流失,粮食产量下降,制约经济发展。本文通过实地调查及资料查阅,阐述了典型黑土区水土流失的现状及特点,并从自然因素和社会因素两方面对水土流失的成因进行分析。在此基础上,有针对性地提出相应的农业措施、生物措施、工程措施等治理方式,以期为黑土区水土流失的防治提供有效参考。
Northeast black soil region is an important grain-producing area in China,but in recent years,with the increasing soil and water loss,soil fertility is also constantly losing,and grain production is declining,which restricts economic development.Therefore,this paper describes the current situation and characteristics of soil and water loss in typical black soil area through field investigation and data consulting,and analyses the causes of soil and water loss from two aspects of natural factors and social factors.It is found that natural factors are the premise and social factors are the dominant factors.On this basis,the corresponding agricultural measures,biological measures and engineering measures are put forward in order to provide effective reference for the prevention and control of soil erosion in black soil region.
