  2. In the second section, three ( 2 co2 ) scenarios only considering climate change alone ( c scenario ) were generated first, using outputs of the giss, gfdl and ukmo gcms, combined with the baseline. then, climate change scenarios including change in climate variability ( c + v scenario ) were produced, based on 3 hypotheses and the weather generator ( wgen ) in dssat. finally, the ceres - wheat model was run under both the ( c + v ) scenarios and the baseline, and the combined effects of climate change and its variability with doubled co2 on whiter wheat production in the studied region were assessed, based on the results simulated comparison

    在上述第2部分,首先利用baseline和國際上通用的3種大氣環流模型( gcms )即giss 、 gfdl和ukmo的有關網格點值,生成了研究區域3種不考慮氣候變率變化的( 2 co _ 2 )氣候變化情景(以下簡稱c情景) ;然後,提出了未來氣候變率可能變化的3種假設,並應用dssat (農業技術轉化決策支持系統)中的wgen (隨機天氣發生器) ,分別生成了研究區域( 2 co _ 2 )條件下兼顧氣候及其變率的氣候變化情景(以下簡稱c + v情景) ;再后,在上述( c + v )情景下分別運行ceres - wheat (作物-環境資源綜合系統-小麥) ,還考慮了大氣co _ 2濃度的直接影響,並與baseline條件下ceres - wheat的模擬值進行比較,在此基礎上評價了( 2 co _ 2 )條件下氣候及其變率變化對研究區域冬小麥生產的影響。
  3. Then the combined gradual effects of climate change and its variability on whiter wheat production in the studied region were analyzed, based on the results simulated by ceres - wheat and all the results at the representative sites were displayed graphically using the gis technology. the main conclusions of this study were as the follows : 1. the temperature has increased during the wheat growing season since the late of 1960s in the huang - huai - hai plain and, it became more evident after the end of 1980s

    研究區域小麥生長期的氣候,自20世紀60年代末已開始變暖,變暖趨勢在80年代以後日益明顯;隨著溫度的上升,太陽輻射總量逐漸減少,溫度變率呈增大的趨勢;雖然降水總量沒有明顯變化,但自20世紀80年代以後,降水變率亦呈增大趨勢,其不穩定性甚於溫度變率的變化。
  4. In this paper, starting with the physical mechanics of land surface hydrologic process and the introduction of the theory in probability statistic distribution, an analytical expression of heterogeneous evapotranspiration efficiency is given which takes heterogeneous soil water content ' s subgrid scale spatial variability into account, through which the parameterization scheme of subgrid scale soil surface ' s evapotranspiration efficiency ( which is generally called mosaic method ) is modified to a statistic - dynamic scheme in which a whole heterogeneity of the grid region is considered

    本文從陸面水文過程的物理機制出發,引進概率統計分佈理論,推導出一種由非均勻土壤含水量次網格尺度空間變率所形成的非均勻蒸發散率解析表達式,從而將通常的次網格尺度地表蒸散率的參數化方案( mosaic方法) ,改進為考慮網格區整體非均勻性的統計-動力參數化方案。
  5. Spatial variability of soil moisture on steep slopeland in loess hill region

    黃土半乾旱丘陵區陡坡地土壤水分空間變異性研究
  6. The relationship between cef and china summer rainfall and that between cef and tropical cyclone frequence ( tcf ) in the northwest pacific ( nwp ) are investigated. lt is found that the several branches of cross - equatorial flow have different interannual variability. periodicity and interdecadal variability. the five channels in the lower troposphere in the monsoon region of the eastern hemisphere have different relationships with china summer rainfall. the results also show that there are obvious relation between the interannual variatin of cef and tcf from july to october in the northwest pacific

    確定了東半球季風區對流層高低層各支越赤道氣流通道的位置,並探討了越赤道氣流與我國夏季降水和西北太平洋上熱帶氣旋發生頻數的年際變化之間的關系。結果表明:季風區夏季的幾支越赤道氣流具有不同的年際變率、周期以及年代際的變化特徵。夏季季風區對流層低層的5支越赤道氣流的強度與我國夏季降水呈不同的相關型。
  7. The main purpose of our paper is to build the coupling pelagic - benthic one - dimensional box model for yscwm, and use it to study the seasonal variability of the vertical structure of each variables, energy flow characteristics, the contribution of microbial loop and the income and expenses of nutrient elements of the ecosystem in this region

    本文的主要研究目標是構建黃海冷水團水域水層-底棲耦合生態系統垂直一維模型,並利用此模型對該海域生態系統各生態變量垂向結構的季節變化特徵、物流能流結構特徵以及微食物環的貢獻和營養鹽的收支循環等問題進行動力學研究。
  8. In the third section, the emphasis was put on evaluation of the gradual effects of climate change in future 50 years. all the three sections drew an outline of global climate change affecting the whiter wheat production at present and in future in the studied region. in the third section, the gradual climate change scenarios considering both climate and its variability in future 50 years ( i. e., 2010, 2030 and 2050 ) were generated, using outputs of the giss transient run and the baseline, adopting the same method described in the second section mentioned above
