( 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。We study the regular of soil water contents in 11 years artificial locust woodland. the results showed that soil water contents are semi - shady > sunny > semi - sunny. so we can draw the conclusion that the reason of differential productivity of artificial locust woodland in different site types is soil water content rather than soil nutrients
對11年人工刺槐林土壤含水量變化規律的研究表明，三個立地類型的刺槐林土壤含水量差異顯著，其土壤含水量從大到小的順序為：半陰坡半陽坡陽坡，因此就可以斷定，在黃土高原現有的土壤養分背景下，引起不同立地類型生產力差異的主要原因不是土壤養分，土壤含水量是引起黃土高原人工刺槐林生產力差異的主要原因。The all hinge of riverbed power station of the kaplan turbine ' s transient is studied in this paper whose background is the water hinge of power station in sha potou on the yellow river
