而海面風是影響溢油油團漂移軌跡和養殖業的重要因素，因此，對舟山海域的海面風進行研究，建立適合此區域的數值預報模式，可為研究該區域海面風作用過程提供數值預報工具，使我們對近海區域海面風場作用中物理因子的影響程度有更定量的認識，並對物理過程和影響機制有更深刻地了解。 -
Then, with the help of gis, i selected 8 soil fertility factors mentioned above and soil texture as parameters, used blocks generated by overlaying each factor theme as assessing unit, modified nemoro fomular, and then i assessed the overall soil fertility quality of wujin city, we know : the soil fertility quality of the city is generally medium or worse, in it, the district of riverine polder the district of menghe even fields the district of taige even fields and the district of hilly lands are on " worse " level, and the district of zhengheng polder the district of lakeside polder and the district of taoge even fields are on " medium " or " better " level
接著在gis支持下，選取以上8項土壤肥力要素並加上土壤質地作為參數，以各要素圖層疊加產生的圖斑作為評價單元，修改內梅羅公式，對武進市土壤肥力質量進行綜合評價，得出：土壤肥力質量中等偏下，其中，沿江圩田區、孟河平田區、太涌平田區和低山丘陵區主要處于「較差」水平，而鄭橫圩田區、沿湖圩田區、洮?平田區主要處于「中等」及「良」水平。 -
Built according to the effect curve reflecting the relationship between fertility factor and crop production, the subordinative function solves the quatitative problem from the gradual change of ambiguous variable. it tallys with the actual situation to define the fertility factor weigh by using hierarchy analysis and combine it with expert ' s knowledge
通過肥力因子與產量的效應曲線建立隸屬函數，解決了模糊變量漸變過程中的定量化問題；引入層次分析結合專家知識確定肥力因子權重，更符合客觀實際，使評價結果更準確。 -
In light of current using situation and drawing on the experience of many scholars researched methods and viewpoints, this thesis made com land, fallow land, orchard, grass land as experimental field in black soil region jlau, which carried out experiment by applying different amounts of n and p fertilization in corn field. by means of collecting the samples of rainfall runoff, erosion silt and surface layer soil before and after rainfall for one year nature precipitation in field, we study the effect of surface runoff on n and p nutrient and fertility degeneration. the results showed : ( l ) there are lots of factors which affect soil erosion and losses of n and p, in which rainfall and rainfall intensity were more important, while rainfall intensity is the most important meteorological phenomena factor
針對當前黑土利用現狀，本文借鑒眾多學者的研究方法和觀點，在吉林農大黑土區選擇利用方式不同的玉米地、休閑地、果園、草地，在玉米區進行了不同數量的施肥，通過野外試驗，採集一年自然降雨產流及泥沙樣品，同時採集降雨前後的耕層土壤樣品，研究了黑土區地表徑流對氮磷養分特徵及肥力退化的影響，結果表明：土壤侵蝕和氮磷的流失受諸多因素的影響，降雨量、降雨強度是重要因子，而降雨強度是影響農田地表徑流養分流失的最重要的氣象因子，特別是暴雨，暴雨徑流中氮磷濃度較平時高得多；隨作物生長，覆蓋度逐漸增加以及不同利用方式下表現的覆蓋度差異，氮磷流失都表現為顯著的差異。 -
At present there are more reports on soil erosion by experts from home and abroad, but most of these reports were about simulation and research based on a single factor. there are little reports on soil erosion on entire watershed, adopted comprehensive research measures according to the principle of ecological system, especially on soil erosion from the intensive farming system on slope lands, watersheds exploited for agroforestry industry, as well as appraisal reports on soil fertility index
目前國內外學者有關水土流失的報道很多，但大多數以單一因素和模擬試驗研究較多，而從生態系統角度出發，採用綜合方法，在小流域尺度上研究水土流失規律較少；對小流域坡耕地綜合農業措施水土保持效應和小流域綜合開發利用過程中水土流失規律研究以及侵蝕土壤肥力評價的研究則更少。 -

Using the methods of summation by giving a mark and main component analysis, the result indicates that the methods of main component analysis is identical better with reality than the methods of summation by giving a mark, the differentiation trend of types of site conditions of cornus officinalis chiefly receives the accuse in soil fertility factor and the general configuration of the earth ' s surface factor
結果表明：主分量分析法與打分求和法相比，以主分量分析法劃分的類型與實際吻合更好；山茱萸立地條件類型的分化趨勢主要受控于土壤肥力因子和地貌因子。 -
The f factor, which possesses an additional genetic unit, is also called sex factor or fertility factor.

Every soil fertility factor was recorded both in the early 1980s and 2000 at the same sample plot. all socio - economic data were derived from interviews with the production team leaders in charge of the sample plots, and were also gathered in both periods. after describing the trends in changes in soil nutrients from the early 1980s to 2000, the dissertation sets up an econometric model to measure the possible impact of socio - economic factors on soil fertility
本研究樣本數據的特點之一是每個樣本地塊都有80年代初和2000年兩個時期的4個土壤肥力因子的觀測值，同時兩個時期的土壤采樣季節、技術以及實驗分析方法等基本相似，這保證了土壤肥力數據具有完全的可比性。 -
