摘　　要：1998年松嫩流域洪涝灾害致使松嫩平原西部风沙土受到洪水冲刷、淤积和长期侵蚀,原本为中低产田的风沙土产量进一步降低。在遭受不同程度洪水侵蚀的风沙土上进行定点定位研究,以探明风沙土水毁耕地土壤理化性质及养分库容的动态变化规律。将黑龙江省松嫩平原西部风沙土遭受洪涝灾害的耕地按照淹水后土体平均含水量划分为轻度、中度、重度3级;在淹水地块进行了3年大豆培肥定位试验。探明了有机肥料的施入可以提高土壤持水性能、土壤养分以及可溶性盐含量,同时培肥地力能够改善大豆产量和品质。提出了风沙土水毁耕地以秸秆有机和鸡粪有机肥为主的培肥措施,建立了风沙土水毁耕地良性施肥体系。The flooding disaster in 1998 resulted in wind-sand soil scoured, deposited and long-term eroded in western of Songnen plain, and the yield of medium and low areas became further lower. This study research on different eroded sand soil located, in order to state the dynamics of the soil physical and chemical properties and nutrient sink. The wind-sand soil eroded by flooding disaster in Heilongjiang Songnen plain is classified into three degrees ：flooding light ,flooding middle and flooding heavily. Located trial was made in three places for three years, and results suggested that organic fertilizer can improve the status of soil water, water retaining capacity, aggregate structure, soil nutrient and soluble salt, at the same time, fertilizer measures can change the soybean yield and quality. We put forward the measures of using chemical fertilizer with bio-organic fertilizer, straw organic fertilizer, poultry dung manure to improve the fertility of water erotion land. The better system of water erosion land fertilization of wind-sand soil have set in the west part of Songnen Plain.
