近年来,土壤的退化问题已经得到了全球性的普遍关注。举有关权威部门的调查显示,截至20世纪90年代,由于管理不当造成的农田退化数量达到5.62亿公顷,并且在此阶段的农田竟然以每年500万到600万的速度退化,可见目前土壤的退化状况不容乐观。尽管,这种情况在在一些发达国家个地区可以得到有效的遏制,但是在非发达国家和地区,土壤的退化不仅没有得到有效制止还在不断地恶化。当然,现阶段的我国也在面临着这个严峻的问题。土壤有机质的损失就是土壤退化的最为重要的表现。不容置疑的是,土壤有机质的流失与徒弟的利用方式有很大的关系,但是值得注意的就是在土地的耕种过程中,会由于土壤中原有的有机质因在空气中暴露被氧化而加速碳的流失。土壤的退化严重影响着土壤中有机质的功能和可持续的管理。因而,本文以土壤有机质的功能和可持续发展作为研究的主题展开研究,旨在提高土壤的科学管理水平,保持土壤有机质的功能,保证我国农业的健康持续发展。
In recent years, the problem of soil degradation has gained global attention. According to a survey conducted by the authoritative department, as of the 1990s, the number of farmland degradation caused by mismanagement reached 562 million hectares and the farmland at this stage was degenerated by 5 million to 6 million annually, showing the current degradation of the soil The situation is not optimistic. Although this situation can be effectively curbed in some developed countries, the degradation of soil in non-developed countries and areas has not only been effectively stopped but also deteriorated continuously. Of course, our country at this stage is also facing this serious problem. The loss of soil organic matter is the most important manifestation of soil degradation. Undoubtedly, the loss of soil organic matter is closely related to the apprentice’s utilization method. However, it is worth noting that in the process of land cultivation, carbon will be accelerated due to oxidation of the original organic matter in the soil due to exposure to air Lost Soil degradation severely affects the functioning and sustainable management of organic matter in the soil. Therefore, this paper studies the function and sustainable development of soil organic matter as the research topic to improve the scientific management level of soil, maintain the function of soil organic matter, and ensure the healthy and sustainable development of agriculture in our country.
