生物技术在沙化土壤修复中的应用

Application of Biotechnology in Desertified Soil Remediation

过去由于耕地过度开垦、草场过载放牧等原因,我国土壤出现严重的沙化、退化现象,变得更加贫瘠。土壤生产力下降的同时,水土严重流失,不仅不利于农业生产,而且会引发沙尘暴等灾害,危害人们的正常生活。在当前可持续发展理念下,为防止生态环境进一步恶化,保护我国农业生产有序推进,需加大力度开展沙化土壤修复工作,将其进行恢复和重建。基于此,分析沙化土壤形成的原因及危害,并探讨沙化土壤中生物技术的应用。

In the past,due to excessive cultivation of arable land and overgrazing of grasslands,China's soil experienced serious desertification and degradation.The soil became even more barren,and soil productivity decreased.At the same time,there was also serious soil erosion,which not only hindered agricultural production but also caused sandstorms,endangering people's normal lives.Under the current concept of sustainable development,in order to prevent further deterioration of the ecological environment and protect the orderly progress of agricultural production in China,it is necessary to vigorously carry out the restoration and reconstruction of desertified soil.Based on this,analyze the causes and hazards of sandy soil formation,and explore the specific application of biotechnology in sandy soil.
