intervale-
The valley bottomed out by the river.
山谷地勢漸低直到河邊。( 5 ) conclusion was obtained by the analyzing and studying the mechanics environment of the rock mass and the landslide on right bank : according to the analysis, the present direction of the maximal principle stress was consistent with the present tectonic stress field, the value of the principle stress increased or reduced in special place, and there was tensile stress region at the 2000m or above it on the left bank, the accumulate and adjustment was very limited in 200 years, the calculated result of the landslide indicated that the landslide on the right bank was stable under the various conditions
（ 5 ）壩址區河谷巖體力學環境及右岸古滑坡體的穩定問題分析得出：河谷巖體應力場的分析顯示，河谷巖體中主應力的方向基本上與現今區域構造應力場的方向一致，在一些特殊地帶巖體的主應力值有所降低或增高，特別是在左岸的2000m高程附近及以上，存在有明顯張應力區。在未來200年流變計算時步范圍內，河谷巖體應力的積累與調整較為有限。同時對滑坡體各種工況條件下的穩定性計算結果表明，右岸古滑坡體在各種工況條件下是處于穩定狀態的。( 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。The results showed that : the integrated ecological risk was presented symmetrically along brahmaputra, and was mitigated from valley farming area to mountain pastoral area ; the hazards of main risk sources to risk suffer in each sub - region was differently, drought was the common risk source and imperils farming and stock raising severely ; aimed at enhancing the ability of fighting drought, controlling flood and stabilizing sand engineering measures should be taken steps to prevent those hazards ; mountain hazards must be controlled in resident area and along arterial traffic ; manual work should be done to void hail in those area where hails attacked heavily ; there is need to promulgated risk knowledge to herdsmen for strengthening their risk consciousness and improve the ability of preventing risk and self - help after hazards happened in the pasturing area
扎囊縣綜合生態風險沿雅魯藏布江呈現對稱型分佈，並由河谷農業區向高山牧業區逐漸降低；各亞區的主要風險源對風險受體的危害強度差異較大，乾旱是共同的風險源，造成的農牧業生產損失最為嚴重；抗風險措施主要有在河谷地帶採取工程措施以提高抗旱、防洪和固沙能力，在半山臺地加強治理居民點及交通沿線的山地災害，在多雹區進行人工消雹；在高寒牧區向牧民傳播風險知識，以加強其風險意識，提高規避風險和災后自救能力。So it had the long distance controlling effect on the sediment in the ordos. it is generally supposed that on the ramp of cratonic basin, the sequence of the epicontinental sea in the ordos is mainly composed of the transgressive system tract and the high stand system tract. this paper shows that it is possible that the incised valley of the low stand system tract can exist on the continental shelf in the basin
鄂爾多斯地區上古生界具有克拉通盆地陸表海緩坡沉積的一般特徵，層序構成一般以海侵和高位體系域為主，本次研究認為在陸表海沉積背景下，除在大陸邊緣附近，在盆地內古大陸架上也可以發育低位體系域的下切河谷充填沉積。On space, from fengman bank in the south and the tributary of second songhua river - wende river valley, to city in the north, total nitrogen in the groundwater is increasing gradually ; and in the east and west, the dividing line is second songhua river which breakthroughs the city, to its east, taking the mangniu river valley with the centre zone, total nitrogen in the groundwater decreasing from the east to the west ; to its west, it decreases gradually from jiuzhan industrial area to gudianzi irrigation area
在空間上，南部由豐滿大壩及二松支流溫德河谷地向北部市區方向，地下水中總氮濃度逐漸升高；東西以貫穿整個城區的第二松花江為分界線，東部以?牛河支流的河谷平原區為中心地帶，地下水中總氮濃度由東向西逐漸降低；西部以九站工業區方向向孤店子井灌區所在地，總氮濃度逐漸降低。Along with several other ancient monuments, it stands on a low ridge over - looking the boyne valley, a place famed in myth and legend
它與其它幾座古代墓碑一樣，矗立在一座低矮的山脊之上，俯瞰著一個以神話傳說而聞名的地區? ?波恩河谷。The results indicated that the lrgr mean winter rainfall longitudinally distributed along river, while the unique topography of lrgr did not obviously have impact on the winter rainfall ; the winter temperature distribution was like belt, which decreased from low latitude to high latitude ; the passing - obstructing effect of lrgr cannot be clearly showed with the winter temperature distribution ; but such effect is obvious over nu - valley and lancang - valley
結果表明：縱向嶺谷區多年平均冬季降水空間上沿河流呈縱向分佈；但縱向嶺谷獨特地形對冬季降水變化的空間分佈影響不明顯；冬季氣候平均溫度大致呈東西向帶狀分佈，由低緯到高緯溫度逐漸遞減；在區域上，縱向嶺谷獨特地形的「通道阻隔」作用對冬季溫度空間分佈的影響不明顯；但在怒江和瀾滄江流域，這種影響則較為明顯。分享友人
