This paper, in the light of the special geological environment and actual project situation of the three gorges reservoir area, puts forward a comprehensive analysis and evaluation system suitable for the stability analysis of the bank landslide of the three gorges reservoir area under the premise of thorough consideration of the water influence on the stability of the bank landslide, and obtains the following achievements in several aspects that have the practical application significance and certain scientific research value : ( 1 ) it is discovered that the water activity is the primary factor of the formation of the new landslide and the revival of the ancient landslide. on the one hand, the rising underwater level reduces the actual stress of landslide ; on the other hand, the long time soaking of the underwater reduces the mechanics intensity of the landslide and the slide belt, both of which reduce directly the landslide stability ; ( 2 ) in view of the special condition of the three gorges reservoir area, this paper analyzes systematically the forces acted on the landslide of the three gorges reservoir area and the force varieties acted on the divided landslide when the water level changes between 175 meters and 145 meters. thus it is more scientific and comprehensive for the analysis of the forces acted on the landslide ; ( 3 ) this paper summaries systematically 10 kinds of typical computation projects by organic combinations of different kinds of situations in the dry season ( nature statue ), rainy season ( rainstorm or rains for a long time condition ), with 175m water level in the reservoir, during the earthquake, with the water level of the reservoir adjusted from 175m to 145m and so on, and produces

本文針對長江三峽庫區特殊的地質環境與工程實際情況，在充分考慮水對庫岸滑體穩定性影響的前提下，提出了一個適用於長江三峽庫岸滑坡體穩定性分析的綜合分析評價體系，並取得了如下幾個方面具有工程實際意義和一定科學研究價值的研究成果： （ 1 ）研究結果發現，水的活動是新滑坡形成或古滑坡復活的主要因素，一方面是由於地下水位升高降低了滑坡體的有效應力，另一方面是由於地下水的長期浸泡降低滑體及滑帶的力學強度，這兩方面的因素均將直接降低滑坡的穩定性； （ 2 ）針對三峽庫區的特殊條件，系統分析了作用於三峽庫區滑坡體上的力系和庫水位在175m與145m間變化時滑體條塊的受力變化，從而使對作用於滑坡體上的力系分析更科學、更全面； （ 3 ）通過對滑體處于旱季（天然狀態） 、雨季（暴雨或長期降雨狀態） 、 175m庫水位、地震以及庫水位由175m調節下降至145m等各種不同情況的有機組合，本文系統地歸納總結出了10種典型計算工況，並具體給出了相應的作用荷載的計算方法，使在庫區岸坡滑體穩定性分析評價時對計算工況選擇及其作用荷載的計算更具規范性； （ 4 ）具體運用c + + builder開發了關于滑坡體穩定性綜合分析評價系統，使對滑坡體穩定性分析計算更方便、更準確； （ 5 ）將上述滑坡體穩定性綜合分析評價系統應用於重慶市豐都縣名山滑坡穩定性分析的具體事例中，分析結果表明，本文所提出滑坡體穩定性綜合分析評價方法對三峽庫區的滑坡穩定性分析是實用可行的。

The result of experimentation on coupling effect of water and fertilizers on spring corn in the three gorges reservoir area indicate that water stresslead the effect low of highness and lai, and the most effect is made in shooting stage ; it has a significant positive correlation between the yield of corn and biomass, and hasn ' t none significant positive correlation between the yield of corn and the weight of roots ; the coupling effect of water and n is significant, but the coupling effect of water and k is not significant, the maximum yield of corn condition fitting - water and medium n, corn absorbs n has a threshold value during the growth, and using superfluous n is able to prick up soil drought and crop drought ; water is the leading factor which effects the yield of corn, next is n and k

摘要三峽庫區春玉米盆栽水肥耦合試驗研究結果表明，水分脅迫導致玉米株高和葉面積指數降低，以拔節期受到影響最大；玉米產量與生物量呈顯著正相關關系，產量與根重無顯著正相關關系；水氮耦合效應顯著，適宜水分和中氮處理下玉米的產量最高，玉米生長發育對氮肥的吸收存在一定的閾值，過多施用氮肥會加劇土壤乾旱和作物乾旱，水和鉀耦合效應對玉米產量影響不顯著；水分是影響玉米產量的主導因素，其次是氮效應和鉀效應。

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
