    結果表明如果按徑流總量計算資源承載力則較大;而按季徑流量計算則較小,這說明喀斯流域的資源承載能力較低,資源量已成為該地區阻礙社會、經濟發展的主要因素之一。
  2. Based on an analysis of causes and basic characteristics of drought in north and south areas of china, it is pointed out that drought in north areas, such as the yellow river basin and the huaihe river basin, was characterized by the severe systematic demand - supply contradiction resulted from the shortage of water resources, and successive drought disasters intensified by hot and dry weather, and that drought in south areas was characterized by the occurrence or successive occurrence of dry years due to hot and dry weather and the seasonal water shortage induced by their geographic and climatic features and insufficient water supply capacity

    摘要以區域乾旱徵分析以及乾旱災害應對策略研究為目的,闡述我國南、北方兩種不同地域類型的區域乾旱成因和基本徵,指出黃淮海區域的乾旱徵主要表現在天然資源短缺引發的系統性深度供需矛盾,以及晴熱少雨氣候加劇這種矛盾而產生的持續乾旱災害;南方地區的乾旱徵主要表現在晴熱少雨氣候導致或連續出現,以及地理氣候徵和供工程容量不足等因素產生的內季節性乾旱缺
  3. The main conclusions are as follows : the hco3 - ion content of zhujiang river changes notably in one hydrological year, especially in wet season and dry season. as for the content of inorganic carbon, that of the xijiang river is the highest, then the beijiang river, and then the dongjiang river. the xijiang river ' s inorganic carbon source was major from karst process in the drainage basin

    得出如下的結論:珠江體hco _ 3 ~ -離子含量在一個中發生顯著變化,別是豐期與期之間波動幅度較大;無機碳含量西江含量最高,其次是北江,東江最低;西江無機碳主要來源於巖溶作用,由於受河流沖刷效應影響,豐期hco _ 3 ~ -離子含量升高;東江流域無機碳主要來源於硅酸鹽巖的碳酸鹽風化過程,豐期hco _ 3 ~ -離子含量無顯著變化;北江無機碳來源於巖溶作用和硅酸鹽巖的碳酸鹽風化過程,受稀釋效應影響,無機碳含量隨量增加而降低。
  4. 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,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,筆者根據有關文氣象臺站的降、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,而際變幅則受山區降際變化及變幅的影響十分明顯.目前,梨園河以西河流量處于上升階段,梨園河以東的河流則處于下降的階段;以黑河幹流鶯落峽文站徑流為代表的走廊中部地區的出山口徑流正處於1990開始的段的上升段.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.預計今後若干內,河西內陸乾旱區東段河流出山口徑流的變化以偏為主,中段、西段河流出山口徑流的變化以平或平偏豐為主
  5. Aimed at the feature of great fluctuation of water flow - rate in rivers and taking the monthly average flow - rate at low water with 90 % guaranty in recent ten years as design flow - rate, the permissible amount of major pollutants discharged into yellow river by lanzhou namely the stochastic environment capacity of waters, was determined by using a stochastic computation mode on the basis of lognormal distribution theory

    摘要針對河流量變化大這一點,採用以對數正態分佈理論為指導的隨機計算模式,以近十90 %保證率最月平均流量為設計流量,確定黃河蘭州段主要污染物的容許排污量,即隨機環境容量。
  6. This paper systematically analyzes the environmental effect of the ebinur lake area dynamic change and its influence on the railway along the lake, and the research establishes water balance equation of the ebinur lake, chooses the two characteristic phases, 1991 1992, 1998 1999, for computing, and concludes that since 1990s, water storage whether in low water period or in high water period is less than that of 1960s, whose lake area was 800km2, and this area basically can reach the target of optimal eco - environment benefit

    本文系統地分析了艾比湖湖面動態變化的生態環境效應及其對沿湖鐵路線的影響。並通過艾比湖量平衡方程式的建立,選擇1991 1992時段) 、 1998 1999(豐時段)兩個徵時段進行計算分析,得出20世紀90代以來,不論是時段儲量,還是豐時段儲量,均小於20世紀60代湖泊面保持800km2所需量,而此面基本可以達到湖區生態環境效益最佳的目標。
  7. This paper firstly applied sequential cluster method to set up the classification standard of precipitation state based on the fact that there are much uncertainty and imprecise characteristics in the precipitation course ; then this paper presented a method which is called markov chain with weights to predicted the future precipitation state by regarding the standardized self - coefficients as weights based on the special characteristics of precipitation being a dependent stochastic variable ; and applied this method to a real hydrological observation station with nearly 50 years precipitation information in shanxi province at last, an ideal result was obtained

    摘要首先基於降過程存在大量不確定性、不精確性的點,應用有序聚類的方法建立降狀況的分級標準;然後針對降量為相依隨機變量的點,採取以規范化的各階自相關系數為權重,用加權的馬爾可夫鏈模型來預測未來降的豐變化狀況;最後以山西省某文站近50的降資料為實例對該方法進行了具體的應用,獲得了較為滿意的結果。
