黄土高原植被建设对土壤干层影响研究进展

Research Progress of the Influence of Vegetation Construction on Soil Dry Layer in the Loess Plateau

为深入了解土壤干层研究现状,为下一步研究土壤干层对植被生态与土壤水分的影响奠定基础,运用文献调研法对土壤干层基本特征、影响因素与危害等方面进行总结剖析,明确当前恢复土壤水分及修复土壤干层主要措施,在人工植被恢复建设中,因地制宜,选择合理的植被配置和土地利用方式,通过人工集流等技术措施,有效地利用水资源,减少土壤干层发育。并提出如何高效率恢复土壤水分,防止土壤干层进一步发育仍是未来的研究重点。

In order to deeply understand the research status of dried soil layer and lay the foundation for the next step of studying the influence of dried soil layer on vegetation ecology and soil moisture,we used the literature research method to summarize and analyze the basic characteristics,influencing factors and hazards of dried soil layer,and clarified the current main measures to restore soil moisture and repair dry soil layers.In the restoration of artificial vegetation,measures should be taken to suit local conditions,and reasonable vegetation configuration and land use methods should be selected,and technical measures such as artificial flow collection can effectively use water resources and reduce the development of dry soil layers.It was pointed out that how to efficiently restore soil moisture and prevent the further development of dry soil layers is still the focus of future research.
