通过对黄土高原不同降水类型区人工乔木林地0~1000cm土层土壤湿度测定和分析,试图揭示和评价黄土高原主要类型人工林地土壤干燥化特征及其区域分布规律,为黄土高原人工林地水分可持续利用和人工植被重建提供科学依据。
Through the determination and analysis of soil moisture in 0 ~ 1000cm soil layer of artificial tree forest in different precipitation areas in the Loess Plateau, attempts were made to reveal and evaluate the characteristics of soil desiccation and its regional distribution on the main types of plantations in the Loess Plateau, Use and reconstruction of artificial vegetation provide the scientific basis.
