mosaic soil
解釋
鑲嵌土壤-
Meanwhile, most aspects about this perspective are concerned, which include quantification of the soil water background of the plateau area, the regional spatial variation of soil water background and variation along the slope, mosaic structure and seasonal changes etc. the results show that : ( 1 ) for the fundamental circumstance for vegetation development is the original debilitated slope, so the perspective of soil water background specially for the loess plateau refers to the soil water conditions on the original slope. ( 2 ) the value of soil water background appears to be a descending trend from south to north based on the difference of vegetation zones. in the forest zone, soil moisture contents beneath 3m depth from the soil surface are more than 12 % usually ; in the forest - pasture zone, the values of soil moisture content beneath 4m depth underground are more than 6 % and stable, and tend to be ascending while the depth increases ; but the values in the dry pasture zone is lingering between 4 % to 6 % from the surface layer to sub - layers
發展了「土壤水分背景」的概念，並以之為基礎對其各個方面進行了研究，使之形成一個相對獨立和完整的體系，主要包括黃土高原土壤水分的背景值、土壤水分背景的區域分異、坡面分異、鑲嵌結構及其季節分異等： （ 1 ）由於植被生長發展、演替的基礎階段是天然草被群落，故認為黃土高原的土壤水分背景在概念上是特指該區天然草被群落下的土壤水分狀況； （ 2 ）黃土高原的土壤水分背景值，根據植被地帶的不同表現出自南向北逐漸降低的規律：森林地帶3米以下土層水分背景值普遍穩定地高於12 ，森林草原地帶4米以下土層水分背景值穩定大於6 ，且均隨土層的加深水分含量逐漸增加，而草原帶的土壤水分背景值自土表至底土層一直在4 6之間徘徊。 -
( 2 ) parts of the area show apparent local climatic properties because of the influence of topography, landcover, and so on. precipitation in mountainous and forest area is usually more affluent than in vicinity, this creates a typical mosaic structure of precipitation distribution like the islands. ( 3 ) soil water is the most significant form of water resources, which is the only water for vegetation uptake
分析結果顯示： （ 1 ）黃土高原地區的降水分佈自東向西、自南向北逐漸減少，東南部可達900多毫米，西北部最低則僅約100毫米，表現出顯著的大陸性氣候特徵； （ 2 ）由於地形等因素的影響，山地森林等局部地區小氣候特徵明顯，降水量高於周圍地區，結果形成降水的島狀鑲嵌結構； （ 3 ）土壤水是黃土高原最重要的水資源之一，它是該區植被水分利用的重要資源。 -
In this paper, starting with the physical mechanics of land surface hydrologic process and the introduction of the theory in probability statistic distribution, an analytical expression of heterogeneous evapotranspiration efficiency is given which takes heterogeneous soil water content ' s subgrid scale spatial variability into account, through which the parameterization scheme of subgrid scale soil surface ' s evapotranspiration efficiency ( which is generally called mosaic method ) is modified to a statistic - dynamic scheme in which a whole heterogeneity of the grid region is considered
本文從陸面水文過程的物理機制出發，引進概率統計分佈理論，推導出一種由非均勻土壤含水量次網格尺度空間變率所形成的非均勻蒸發散率解析表達式，從而將通常的次網格尺度地表蒸散率的參數化方案（ mosaic方法） ，改進為考慮網格區整體非均勻性的統計-動力參數化方案。 -
( 3 ) the distributions of both regional soil moisture and available soil water are similar, high in the south and low in the north, and have a mosaic structure similar to the regional precipitation distribution. ( 4 ) the soil moisture of the original slope is influenced s
（ 4 ）提出「初始萎蔫濕度」的概念，並將其作為判別土壤干化發生的標準；以此為依據，計算並確定了中部黃土高原典型地區的土壤干化層發生分佈情況。
