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。Many academicians researched their formation and accumulation mechanism and put forward manifold mechanisms, including the special mechanism of minority liquid molecular controlling the accumulation of lens reservoir by unknown gravitation, difference between liquid pressure compelling hydrocarbon to accumulate firstly in the lens reservoir, along cranny in the case of hydrocarbon replacing pore water in the lenticular body under capillary pressure, difference breakthrough employing hydrocarbon entering lens reservoir and so on
國內外學者提出了多種成藏機制，包括未知重力運動機製作用下，少數流體分子的個別特性控制透鏡狀砂巖油藏聚集；毛細管力作用下油氣替換透鏡體中的孔隙水；烴濃度差是油氣向砂體運移的主要動力；流體壓力差使油氣首先沿著裂隙向砂巖透鏡體中運移、聚集而成藏；差異突破作用使砂巖透鏡體成藏等。
