摘要
土地退化问题是社会发展到一定阶段,伴随开发利用土地资源而生的一种限制农业生产、影响生态安全、威胁自然环境的重大科学问题。针对这一科学问题,国内外学者和协会均开展了相关研究,对土壤的显性退化给予了足够的重视,针对各类显性退化问题开展了富有成效的科学研究,取得了显著的成效。然而,截止目前对土壤的隐性退化还缺乏足够的重视,对其发生机理缺乏认知、对其危害性认识不足,对发生机理尚未探明。
Land degradation is a major scientific problem that limits agricultural production, affects ecological security and threatens the natural environment, which comes along with the exploitation of land resources at a certain stage of social development. In response to this scientific problem, scholars and associations at home and abroad have conducted relevant researches, paid enough attention to the explicit degradation of soil, carried out fruitful scientific researches on various explicit degradation problems, and achieved remarkable results. However, up to now, there is still a lack of sufficient attention to the hidden degradation of soil, a lack of knowledge of its occurrence mechanism, a lack of understanding of its harmfulness, and a lack of understanding of the occurrence mechanism.
