低覆盖度治沙理论及其在干旱半干旱区的应用初探

Theory of Low Coverage Sand Control and Its Application in Arid and Semi-arid Areas

近年来,为了防治土地沙化和水土流失,实现固沙育林的可持续发展目标,我国提出了低覆盖度治沙理论,并在沙化严重的区域试推行,在防沙治沙工作中取得了显著的成效。通过对低覆盖度治沙理论进行研究,并分析了该理论在干旱半干旱区的应用,为推进我国防治沙化工作提供参考。

In recent years,in order to prevent and control land desertification and soil erosion,and to achieve the goal of sustainable development of sand fixation and forest cultivation,the theory of low coverage sand control has been put forward in China,which has been carried out in areas with serious desertification,and has achieved remarkable results in the work of sand control.Based on the study of the theory,the application of the theory in arid and semi-arid areas is analyzed,which provides a reference for the prevention and control of desertification in China.
