  4. The study showed that n and p runoff concentrate in storm is higher that norm. with the cover level increasing and different utilization manners, losses of n and p nutrient showed notable divergence. ( 2 ) with the increasing of rainfall and rainfall intensity, losses amounts of runoff silt in fallow field, com field and orchard field showed rising, while was stable in grass field

    黑土徑流泥沙流失量，總的趨勢是隨降雨量、降雨強度增加，休閑地、玉米地、果園的流失量有增加的趨勢，而草地泥沙流失量無增加的趨勢，基本衡定；徑流泥沙流失量及泥沙n 、 p流失隨植被覆蓋的增加而降低。
  5. 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。
