本文採用地質和地球物理相結合的研究思路，運用多種技術手段和方法；在充分利用已有構造圖資料和構造要素資料的基礎上，運用地層層序邊界不整合分析法、地層厚度對比分析法，結合地震資料的精細解釋、古構造和古地貌的恢復、構造演化史研究、含油氣系統的研究，和區域和局部、平面和剖面、時間和空間的結合研究，對塔里木盆地和田古隆起構造演化及油氣關系進行了綜合分析，認為： （ 1 ）和田古隆起為一沉積?剝蝕性古隆起；形成於志留-泥盆紀；其構造演化可分為三個階段，即加里東期的抬升剝蝕階段、海西期的沉積階段和喜山期的破壞階段，最終由古隆起演變為一斜坡帶。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
