河成階地土Normally water resources is affected by human activities and climatic change, but it is affected mainly by climatic change in runoff forming regions located in the high and middle mountainous area in the northwestern china. river runoff in the hexi inland arid region all originates from the qilian mt. area and the change of mountainous runoff resulted from global weather warming up and will bring an important effect to the development of society and economy in the hexi region. so the response on mountainous runoff and its changing trends are analyzed on the basis of the measured data of precipitation, air temperature, and discharges observed from some weather and hydrologic stations in the studied area. the results show that seasonal variation of mountainous runoff in the hexi inland region is mainly affected by the river ' s geographical location and supply source, and the yearly change by precipitation and that in the west of the region by air temperature besides precipitation. there are some obviously regional differences in the influences of climatic change on surface runoff in the hexi inland arid region, that is, rivers runoff in the west of the hexi area have been increasing and rivers in the east part have been decreasing, and the rivers runoff in the central part presented slowly increase trend, such as the heihe river, but it is not quite obvious
一般情況下，水資源的變化主要受氣候變化和人類活動的影響，但在位於我國西北內陸乾旱地區的中高山地帶，徑流的形成主要受前者的影響.甘肅省的河西內陸乾旱區是該省重要的工農業生產和經濟開發區，這里各項社會和經濟活動與出山徑流的變化都有著十分密切的關系.因此，筆者根據有關水文氣象臺站的降水、氣溫和徑流觀測資料，分析了以黑河、昌馬河、西營河等主要河流為代表的河西內陸區出山徑流的變化特徵與規律.結果表明，河西內陸區出山口徑流的季節變化主要受地理位置和河流補給來源的影響，而年際變幅則受山區降水量年際變化及變幅的影響十分明顯.目前，梨園河以西河流水量處于上升階段，梨園河以東的河流則處于下降的階段;以黑河幹流鶯落峽水文站年徑流為代表的走廊中部地區的出山口徑流正處於1990年開始的枯水段的上升段.但總體而言，河西內陸乾旱區出山口徑流的變化相對比較穩定.預計今後若干年內，河西內陸乾旱區東段河流出山口徑流的變化以偏枯為主，中段、西段河流出山口徑流的變化以平水或平水偏豐為主From the dongying formation ( ed ) to neogene, the shahejie formation was located in the late diagenetic stage a1 ~ a2 ; the oil and gas pools formed in a wide scale. at present the lower e2s3, with overmatured source rocks and low porosity reservoir rocks, gets into the late diagenetic stage b - c in the northern qibei sag where is not favorable for petroleum accumulation, but the others of the shahejie formation are locate still in the late diagenetic stage a1 - a2 and propitious to form oil and gas pools based on the diagenetic numerical modeling under the condition of overpressure, we build a multiple unit cubic equation model for porosity prediction, as the result of the application of qibei sag, the prediction error is less than 2 %, and the precision excess that of foreign same model

（ 5 ）通過對岷江疊溪古堰塞湖湖相沉積中的河流階地分析可知，階地的形成不僅僅是由於新構造運動的間歇性抬升作用，由於堰塞湖的潰決引起洪水下泄，導致河流侵蝕基準面的下降也可以形成階地。( 6 ) conclusion was obtained by the analyzing the mechanics environment and the stability of the lanslide on the right bank after the dam built : the value of the rock mass stress increased and the tensile stress region obviously reduced, the direction of the principal stress was unchangeable the dam and the landslide were stable under the dangerous condition ( the reservoir and at the same time the earthquake was viii ), but when the water lever suddenly fell and did not think of other force, safe factor evidently reduced, the dam and the landslide will be destroyed under the most dangerous condition ( the water lever suddenly fell and at the same time the earthquake was vi ) ; the stability of the landslide will be destroyed by the horizontal thrust under the most dangerous condition or ; the physical and mechanical parameter will be reduced due to long period filter, the landslide will be destroyed too
（ 6 ）建壩工程荷載條件下河谷巖體力學環境分析及右岸古滑坡體的穩定問題分析得出：建壩后河谷的巖體應力量值明顯增高，同時左岸的張應力區的范圍及量值明顯減小，主應力的方向依然與模型的底邊界垂直；大壩建成后逐漸蓄水階段以及同時考慮本區最強地震力的作用等各種不同的工況條件時，滑坡體及壩體總體上仍處于穩定狀態；水位驟降時，在未考慮其他外力作用的情況時，滑體的安全系數將顯著降低。若考慮水位驟降及本區最大地震力的共同作用，壩體將在滑坡體下滑推力的作用下產生破壞；建壩后水平推力對右岸古滑坡體穩定性的影響分析可以看出，在最危險的工況條件下，壩體及滑坡體也將處于臨界狀態；在長期滲透變形的作用下，由於滑帶的物理力學參數的降低而有可能導致壩體失穩破壞。This theme selected weihe river round tianshui, jinhe river round binxian, bahe river round lantian and luohe river round luochuan to study the evolutionary model of river terraces in the mid - tail of weihe river. we have built the cross - section of each river, and analyzed the evolution of each river terrace in the mid - tail of weihe river according to the velocity of downcuting and lateral erosion

而以往的河道研究大多數是通過地面調查和地形圖室內對比分析來研究的（少數運用航片） ，由於受人的視域范圍及調查工作路線的布置的復雜度影響，對區域宏觀尺度下的地質構造、長江沙洲、漫灘、階地及河流微觀領域的懸浮物等作綜合性的研究便成為了瓶頸。The dislocation interfaces of early stage were controlled by the slide of the ne fold. the dominant dislocation interfaces, in the dam area, is the one of the second stage, which resulted from the slide of the lava layer and lagerkluftes from nw to se because of the affect of the majiaheba faultage ' s thrusting overriding to the dam area from nw to se. the dislocation interfaces of the third stage were the result of the overprint of the structure of ne to the one of nw
早期階段形成的錯動帶受控于北東向縱彎褶皺的層間彎滑機制；第二階段形成的錯動帶在壩區佔主導地位，它們是由於北東向馬家河壩斷層由北西向南東的滑脫逆沖推覆影響壩區，並造成壩區向南東緩傾的巖層沿原生構造面向南東滑動的結果；第三階段形成的錯動帶則是由於北西向構造疊加於早期北東向構造之上而致。The same grade terrace height beside the river is surveyed at almost the same level, proved that the hidden fault under the river never moved after
