摘    要:黑土是一种自然肥力很高的耕作土壤,主要成片分布在我国东北的松嫩平原。以黑土为主体的松嫩平原是国家重要的商品粮基地,对国家的粮食供给发挥着极其重要的作用。黑土资源作为农业利用是发挥其资源优势的最佳利用方式。由于自然和人为因素的共同作用,黑土的质量发生了严重的退化,数量也急剧减少。本文在分析其现状和退化原因的基础上,探讨黑土的农业可持续利用,为东北地区农业的持续发展提供参考。

关 键 词:黑土资源  可持续利用  东北地区

Abstract:Black soil is a kind of cultivated soil with high natural fertility, which stretches like a stripe across the Songnen plain in Northeast China, and contributes a lot to the food supply for the northeast plain even for the whole country. According to the natural and social economic characteristics of black soil, the black soil for agriculture is the most suitable. Because of complicated function of natural and artificial factors, the quality and quantity of black soil decreased and degenerated heavily. In the paper , the status in quo and the reasons for the decrease and degeneration are analyzed, and the sustainable use of the black soil is discussed,which provide a reference for the sustainable development of a-griculture in Northeast China.
