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。Cultivated area ( area under cultivation ) ： refers to farmland which is plowed constantly for growing crops, including cultivated land, newly cultivated land in the current year, farmland left without cultivation for less th an three years and fallow land in the current year, rotation land, rotation land of grass and crops, farmland with some fruit trees, mulberry trees and other trees and cultivated seashore land, lake land, and etc
