【摘要】：干表層(DSL,Dry Surface Layer)是干旱半干旱地區(qū)土-氣界面的重要組成部分,影響著陸地水分循環(huán)。文章以土壤物理學、土壤水動力學、土壤熱力學和水文地質(zhì)學的基本理論為指導,在綜合分析前人資料的基礎(chǔ)上,結(jié)合室內(nèi)物理試驗的部分觀測成果,界定了干表層的概念,探討了此概念的內(nèi)涵與外延;辨析了干表層和(下伏)土壤干層兩個概念的關(guān)系;闡明了干表層與地下水位埋深的關(guān)系,干表層對降雨入滲、蒸發(fā)和植被的影響。
[Abstract]:Dry surface layer dry Surface layer is an important part of soil-gas interface in arid and semi-arid areas, which affects the terrestrial water cycle. Under the guidance of the basic theories of soil physics, soil hydrodynamics, soil thermodynamics and hydrogeology, based on the comprehensive analysis of previous data and some observations of indoor physical experiments, the paper defines the concept of dry surface layer. The connotation and extension of this concept are discussed, the relationship between dry surface layer and (underlying) soil dry layer is analyzed, and the relationship between dry surface layer and buried depth of groundwater level, the influence of dry surface layer on rainfall infiltration, evaporation and vegetation is expounded.
