  1. 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。

  5. With reference to calculation methods of solar radiation within domestic and abroad literature and with the help of our country ' s dem ( with its resolution is 1 km x 1 km ), we build a new model for potential solar radiation calculation combining with pci geomatica ' s platform. in the calculation, hypothesis is that insofar one clear day in more than one year as the biggest value of solar radiation of one day in many years is defined as potential value of daily global solar radiation, we also consider the infection of the slope, aspect and its geometry relations affect on solar radiation. we calculate potential solar radiation which maybe useful for research the distribution of solar energy and build large - scale grid database of our country ' s solar radiation

    本研究試圖在借國內外已有的太陽輻射計算方法的基礎上,利用全國的1 : 100萬數字高程模型數據( grid大小1km 1km )為數據源,以pcigeomatica為計算平臺,以全國多的太陽輻射日觀測數據進行模式驗證,在晴天無雲的理想條件下,根據太陽光線與實際地形間的幾何關系,研究坡度、坡向等地形因子對太陽輻射的影響,探討太陽輻射在復雜地表上的分配規律,力求尋找潛在太陽總輻射合理的計算方法,為研究太陽輻射時空分佈特徵和建立全國尺度的太陽輻射柵格數據庫奠定基礎,為大尺度上的生態學過程研究提供基礎信息。
