摘　　要：黑土地作为地球上最为珍贵且稀有的土壤资源之一,成为全国重要商品粮生产基地的根本。长期以来,由于存在持续高强度开发利用以及“重用轻养”等问题,导致黑土地面积不断减少,土层不断变薄,地力不断下降,污染不断加重。如果不尽快进行有效的保护,未来黑土地必将会成为制约农业可持续发展甚至威胁全国粮食安全的重要因素。因此,研究如何全面加强黑土地保护,增厚黑土地土层,提升黑土地地力,减轻黑土地污染,构建“管当前更管长远”的长效保护机制,对实现农业可持续发展、保障其粮食安全、维护生态系统平衡等具有重大意义。As one of the most precious and rare soil resources on the earth,black land has become the foundation of an important commodity grain production base in China.For a long time,due to problems such as sustained and intensive development and utilization,as well as"heavy utilization and light maintenance",the area of black land has been continuously reduced,the soil layer has been continuously thinned,the soil strength has been continuously decreased,and pollution has been continuously exacerbated.If effective protection is not carried out as soon as possible,the black land will inevitably become an important factor restricting the sustainable development of agriculture and even threatening the national food security in the future.Therefore,studying how to comprehensively strengthen the protection of black land,thicken the soil layer of black land,improve the soil strength of black land,reduce black land pollution,and establish a long-term protection mechanism of"managing the current and more long-term"is of great significance for achieving sustainable agricultural development,ensuring food security,and maintaining ecosystem balance.
