  1. Formless, the long slope fell away before them, descending into the dark

    無形中，長坡開始傾斜向下，伸入黑暗之中。
  2. The density with the biodiversity increasing shows " m " model. ( 3 ) the correlation analysis shows : elevation, slope, development stage and biomass are main factors which affect the biodiversity pattern in the research region. the biodiversity of the quercus aliena var. acutesrata community shows the patterns with the elevation and slope affecting : on sunny slope, the species diversity increases with the elevation increasing below the attitude of 1640m and its climax is at this attitude ( the diversity index h = 1. 68 ), upward this point, the diversity index descends slowly. the evenness shows ascend trend with the elevation upward, its climax point at 1800m ( the evenness index jsw = 0. 78 ), then descending after this point

    （ 5 ）通過分析，銳齒棟群落生物量與生物多樣性呈現如下關系:在海拔1500一170枷范圍內，銳齒棟群落生物量與物種多樣性之間呈單峰曲線關系;在海拔1700一1900m范圍內，生物量與物種多樣性之間呈不明顯的波動關系;在海拔1900一2100m范圍內，生物量隨物種多樣性的增加而增大，通過對不同高程內生物量與物種多樣性分析發現，隨著海拔的上升，最大生物量對應的物種多樣性略有增加趨勢;在相同海拔和坡向條件下，生物量與物種多樣性之間也呈典型的單峰曲線關系;群落凈生產力與物種多樣性之間總體上也呈單峰曲線關系。
  3. 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。
  4. On the other hand, the coastal system ' s natural adaptive response ( resilience and resistance ) to sea - level rise would induce or increase the potential risk. the changes of the coastal risk to sea - level rise are related to the coastal environment ( geology, geomorphology, coastal height, coastal slope and local ascend and subsidence trend ). the coasts with high elevation, steep coastal slope, rocky cliff, and ascending stabilization are considered to be of higher autonomous adaptive capacity, and the lower autonomous adaptive capacity areas generally occur at lower - lying beach areas and delta coasts where coastal slope is low and the crust is descending

    另一方面，海岸帶對海平面變化的自然適應能力（ 「彈力」和「阻力」 ）將使其對海平面變化的「敏感性」減少或增大，海岸自然適應能力與海岸帶的海岸環境（地質、地貌、海岸高程、海岸坡度，地殼升降運動等）有關，海拔高、海岸坡度大、地殼長期穩定上升的基巖海岸的自然適應能力較強，反之，海岸坡度平緩、地殼長期下降、地勢平坦的平原海岸和三角洲海岸的自然適應能力較弱。
